What is an audio interface?

An audio interface is a piece of hardware that expands and improves the sonic capabilities of a computer. Some audio interfaces give you the ability to connect professional microphones, instruments and other kinds of signals to a computer, and output a variety of signals as well. In addition to expanding your inputs and outputs, audio interfaces can also greatly improve the sound quality of your computer. Every time you record new audio or listen through speakers and headphones, the audio interface will reproduce a more accurate representation of the sounds. They’re an absolutely essential component in computer-based audio production. They’re used for recording music and podcasts, and in video post production for recording voice-overs and sound design.

Why would I use an audio interface?

Audio interfaces are used when more a professional level of audio performance is required from a computer, and when one or more professional microphones, instruments and other kinds of signals need to be routed into or out of a computer.

How is an audio interface different from a sound card?

When an audio interface is used with a computer, it acts as the computer’s sound card. In this sense, an audio interface is very similar to a consumer sound card. However, the similarities end there. A good audio interface not only enables you to connect an assortment of different analog and digital signals, it also provides a more accurate digital clock and superior analog circuitry that improves the overall sound quality. You can achieve an entirely different level of audio than you would by just using the stock sound card that comes with a computer.

How does an audio interface connect to my computer?

Some audio interfaces connect to computers through common USB ports, while others use more esoteric connections like PCMCIA slots. When you’re choosing an audio interface, it’s very important to determine the specific kind of port that’s available on your computer. This will help you find an audio interface that will be compatible with your computer, and narrow down the number of possible models from which you can choose.

There are lots of audio interfaces available that connect through the USB 1.0 and USB 2.0 ports. There are also many audio interfaces that connect through FireWire ports. If you’re using a notebook computer, there are interfaces available that connect through various kinds of ExpressCard slots, and if you’re using a desktop computer, there are models that connect through a variety of PCI card slots. If you know what kind of port you’re going to use on your computer, you can start shopping for the ideal audio interface to suit your needs.

Which one is the best port to use to connect an audio interface to a computer?

This depends on your specific needs. If you plan on tracking and overdubbing with multiple microphones or instruments simultaneously, you’re better off using a high-speed port such as FireWire. If you don’t plan on recording with more than two microphones at a time, you’ll likely be fine just using a USB 1.0 interface. The more demanding your needs, the higher the bandwidth of an interface you’re going to need. The hierarchy of interface bandwidth speeds from lowest to highest goes from: USB 1.0, USB 2.0, FireWire, PCMCIA/ExpressCard, PCI.

How many inputs and outputs am I going to need on my audio interface?

That depends entirely on the kind of work you want to do with your audio interface. If you plan on recording with multiple professional microphones, you need to look for an audio interface with multiple XLR microphone inputs. If you’re going to be recording voice-overs for video production, you may need an audio interface with only a single XLR input. If you’re going to DJ with a computer, it’s a good idea to choose an audio interface with four line-level outputs (two outputs are used to send your stereo mix to the house sound system, the other two outputs are used to privately cue songs).

What features does an audio interface need in order to connect professional mics?

If your primary need is the ability to connect microphones to a computer, you should look for an audio interface with XLR microphone inputs. Professional microphones connect with three-pin XLR jacks. XLR connectors are desirable because they lock into place and provide a more secure audio connection. An audio interface outfitted with microphone inputs will typically come with anywhere from one to eight XLR inputs.

Many audio interfaces come with jacks called “combo” inputs. This kind of jack combines a three pin XLR input with a 1/4” TRS input in one socket. Combo inputs tend to confuse people, because they look different than XLR and 1/4” TRS inputs, yet they accept both kinds of plugs. It’s important to familiarize yourself with combo inputs, so you know what they are when you’re deciding which interface to purchase.

What is “Phantom Power” and why would I need it?

Some microphones require a little flow of electricity in order to operate, while other kinds of microphones are capable of picking up sound without any power at all. Certain kinds of microphones run on batteries, while other kinds of microphones are fed power from the device that they’re plugged into. It’s called “phantom power” when the device that the microphone is plugged into supplies it with electricity. Most audio interfaces that feature mic inputs will also supply phantom power. Because only certain kinds of microphones require phantom power, audio interfaces have a switch to turn it on and off. Phantom power tends to intimidate beginners because it just sounds spooky. Fear not. Using phantom power is about as complicated as flipping a light switch to turn on a table lamp. Besides being called phantom power, it is also referred to as “+48V.”

What are line-level TRS inputs and outputs, and why would I need them?

Line-level inputs and outputs can be very useful; however, to use them properly you must first understand the distinction between mic-level and line-level. Microphones output a very weak signal. The signal is so weak that it needs to be boosted up by a preamp when connected to a mic input. Line-level audio signals are much stronger than mic-level signals, and require no additional amplification. Therefore, line-level signals need a different kind of input than microphones do.

Line-level inputs and outputs on audio interfaces usually show up as 1/4” TRS jacks or 1/4" TS jacks. 1/4” is the diameter of the plug and TRS stands for Tip, Ring and Sleeve; TS for Tip, Sleeve. TRS connections are desirable because they provide a balanced (grounded) connection, which is better at rejecting noise that long cable runs can pick up, or reducing "ground" hum. An example of when you would use line-level inputs is when you’re recording the audio from a keyboard. Most professional keyboards have stereo line-level outputs. You can connect these directly to the line-level inputs on an audio interface. When you’re connecting studio monitors (powered speakers) to an audio interface, you plug them into the line-level outputs. You can also use line-level inputs and outputs to connect external effects, compressors, limiters and all kinds of stuff. Other connectors include 3/8" mini and RCA (phono) connectors. 

What are MIDI ports, and are they important to me?

MIDI ins and outs are found on many audio interfaces. They allow you to send MIDI information into and out of a computer. If you’re not familiar with MIDI, just think of it as a simple language that enables pieces of music-oriented hardware to communicate with each other. For example, if you connect the MIDI Out of your audio interface to the MIDI In on a digital piano, you can send a command from your audio software on your computer that tells the digital piano to play a C flat.

People use MIDI ports for all kinds of things. Like in the example mentioned previously, they’re often used to connect external MIDI instruments. You could create a MIDI sequence on a synthesizer, and then bring this sequence into your audio software with the MIDI interface on your audio interface. The beauty is that the MIDI sequence is just a series of commands, so when you record it into your DAW you can completely change it and turn it into something new. MIDI ports are also used to connect hardware control surfaces, keyboard controllers and a wide range of other equipment and devices.

What are S/PDIF connectors, and why would I need them?

S/PDIF is simply a digital audio format. Just think of it as a digital version of an analog audio connection. S/PDIF stands for Sony/Phillips Digital Interconnect Format. One of the reasons S/PDIF tends to confuse people is that it’s used on different kinds of jacks. The most common kind of S/PDIF connector is a coaxial jack. Unfortunately, this just adds another layer of confusion, because a digital coaxial jack looks exactly like a common analog RCA phono jack. It gets more confusing because a single analog RCA jack can only pass a mono audio signal, while a single coaxial S/PDIF jack can pass a stereo signal. If you weren’t confused enough, the S/PDIF format can also be sent through optical TOSLINK connectors, which look nothing at all like coaxial RCA jacks.

The good news is that you don’t have to worry about any of this stuff. S/PDIF connectors are found on many audio interfaces, and they can be really useful. S/PDIF jacks usually come in pairs, with one for input and the other for output. In order to put them to use, you just need other equipment with S/PDIF input and outputs to connect to them. For example, using S/PDIF inputs and outputs is a common way to connect external effects modules.

What are ADAT connectors, and how do they help my recording?

Like S/PDIF, ADAT is just another kind of digital audio format. While S/PDIF is limited to passing stereo digital audio signals, ADAT is capable of passing eight independent channels of digital audio. This is what makes ADAT inputs and outputs such a useful thing to have on an audio interface. If an interface has an ADAT input, you can buy a separate piece of equipment that will give you eight additional XLR microphone inputs into your computer. The components to which you connect ADAT ports are sometimes referred to as “Lightpipe expanders.”

ADAT inputs and outputs tend to confuse people, too. The term ADAT used to refer to a specific kind of digital-audio media. In the 1990s, ADAT machines were a very popular kind of multi-track recorder. They recorded digital audio onto Super VHS cassettes. ADAT tapes and machines have completely disappeared from the pro audio world, but thankfully the digital format that they utilized lives on in today’s audio interfaces.

An ADAT jack is an optical connection, and fiber optic cables are used to connect ADAT Lightpipe expanders. It should be noted that the terms ADAT, Lightpipe and TOSLINK are sometimes used interchangeably. Some interfaces allow you to switch a TOSLINK connector between ADAT and S/PDIF.

What are Word Clock inputs and outputs, and why would I need them?

All digital audio equipment runs on an internal clock. The confusion about this technology kicks in right away because the clock isn’t a physical device; it’s just a series of digital pulses. Even though clocks are just digital pulses, they are not all created equal and like regular clocks, run at slightly different rates from each other. When connecting two digital devices, both need to see only one clock to avoid problems that manifest as clicks and pops in the analog audio. Higher-quality audio equipment will often come equipped with a more accurate clock. An accurate clock makes a piece of equipment sound better. Higher-quality audio interfaces will sometimes feature Word Clock inputs and outputs, so you can sync them with other equipment. Word Clock sync is not the same thing as SMPTE time code sync. The reason you sync Word Clock from device to device is to maintain the collective sonic performance of the gear. It has nothing to do with syncing sound to picture.

If you have a piece of gear that has a superior clock and a Word Clock output, you can attach it to your audio interface’s Word Clock input and assign the external clock as its master. Several pieces of gear can be synced to a single master clock. This will make every digital operation in the separate devices fire in perfect unison, and make your recordings sound better. Here’s an analogy. Picture a large farm with a massive sprinkler system running to irrigate its crops. If the sprinklers are not synced to a master clock, they will all be rotating and spraying water randomly. If the irrigation system is synced to a master clock, every sprinkler will rotate and shoot out water in prefect sync. If you had a really fine-tuned clock as the master, every droplet of water would hit the plants at the same exact moment. It’s not uncommon for an audio devotee to spend over $1,000 just on a dedicated clock for their studio.

What is “Direct Monitoring,” and is it something I should have?

Any time you record sound into a computer with an audio interface, you are going to experience some degree of “latency.” If you’re not familiar with latency, think of it as the delay in time from the moment you make a command until the moment your command is carried out. If you strike a bell with a mallet, you will hear the sound of the bell ringing instantly. However, when you need to pipe commands through a computer, things don’t happen as immediately.

When you plug a microphone into an audio interface and say “Check 1-2-3,” that sound has to travel on a long journey before you can hear it in your headphones:

  1. The sound is picked up by the capsule in the mic;
  2. Then it is sent through the mic cable into the audio interface;
  3. It’s converted into digital audio and sent to the computer;
  4. The computer routes the digital audio to the DAW audio software;
  5. The audio software receives, processes and sends it back out;
  6. The digital audio travels back to the audio interface;
  7. The audio interface converts the digital audio back into analog and sends it out to the headphones.

That’s a pretty long trip just so you can hear “Check 1-2-3” in the headphones, right? The resulting latency can sometimes distract musicians and make it difficult for them to perform. This is where the direct monitor knob comes in. When you use direct monitoring, you hear the analog audio that is being plugged directly into the interface, as opposed to hearing it after it’s been sent out to the computer and back. This nearly eliminates the latency, and makes the musician happier. Direct monitoring is usually only found on USB 1.0 audio interfaces, because their slower speed makes them more latency prone. Unfortunately, this functionality isn’t referred to as “direct monitoring” by every manufacturer. Some interfaces have direct monitoring controls, but call it by another name. If you see a USB 1.0 interface with a knob that has “mix” on one side and “computer” on the other, then it has a direct monitoring feature.  

What accessories should I get for my audio interface?

Audio interfaces often serve as the heart of a recording studio. Most of the essential tools used in a studio will be connected to the interface directly and indirectly. Of them all, powered studio monitors tend to be the most common tools used with audio interfaces. The cables will vary in length, depending on your setup, with terminations that are appropriate for each item. These might be ¼” TS to ¼’ TS, ¼” TRS to ¼” TRS, ¼” TRS to XLR, XLR to XLR, etc.

With powered monitors in place, you’ll be able to properly hear what you’re working on. When you need to monitor your work privately, a good pair of studio headphones is an essential tool.

The need to plug professional-quality microphones into a computer is the most common reason people purchase audio interfaces. Naturally, having a few good studio microphones to use with your audio interface is a good idea. Mix it up and buy a variety of mics. Having a solid dynamic microphone is a great place to start. Adding a large diaphragm condenser microphone will really expand your sonic palette and let you make good use of your phantom-power switches. Small diaphragm condenser microphones are really great for capturing cymbals and various instruments. And a ribbon mic will round out your mic collection with its ability to capture smooth mid frequencies.

The cable that you use to connect the microphone to the interface can make a difference. Spending a little more on a nicely made XLR cable usually proves to be a wise long-term investment (providing that you don’t abuse it too much).

Very helpful article for a beginner.  Please consider updating it at least annually...

Very nice article. Nicely explained and organized to be understood. I would suggest adding in the "Items discussed in article" audio interfaces themselves. 

Superb article for beginners! Great Job!

Extremely informative article and cleared up a number of terms that I misunderstood.  Thank you for sharing your knowledge, this is an essential read for anyone new to the world of audio interfaces and keen to produce music or podcasts on home computers.

Simple but informative.  B&H does a great job!  If ever in NYC visit there store; it's a candy land of electronics and equipment.

I bookmarked your excellent article!
It was very informative, even for an old salt, audio recording engineer like me.
Consider expanding this article with a couple of signal flow charts for mics, monitors,
recording systems, etc. for newbies and oldies to create a budget for a small studio.
I was still recording on dual 24-track machines running at 30-ips with pro-grade DBX
& Dolby noise reduction when Analog Video Discs and CD's came on the market.
It's certainly a different world now -- editing digitally is way cooler than splicing
a 2" master tape while the Artist & Producer are watching over your shoulder
from 15-feet away -- holding their breath, because even a first gen copy was not
an acceptable subsitute for the original by most engineers and artists.
We all wanted the CD to be as close as possible to our studio masters.
Today, the buyer is lucky if they buy something that resembles the original and
hasn't been VBR'd to death. Again thank you for your primer on digital.

thanks for the information

Hi,

Could you please suggest me which type of audio interface I need yo buy  to connect my Yamaha PSR E333 portable Piano with my notebook(Dell inspiron 11 3000).  My Piano have TRS output I believe. Your suggestion must be appreciated since it will guide me to establish my own song production unit.

Regards,

Sudheer

Hi Sudheer -

The TRS headphone output may be connected to this interface:

The Scarlett 2i2 from Focusrite is a 2 input, 2 output portable USB recording interface featuring two Focusrite preamps, housed in an anodized aluminum unibody chassis that is solid enough to take on the road. The preamps offer transparent, low-noise and low-distortion performance with sufficient available headroom for using moving coil, condenser or ribbon microphones. Phantom power is switchable.

The front-panel Neutrik combo connectors can used to connect both line and instrument level signals as well as microphones. This makes it perfect for recording the output of a synthesizer or stage piano, while a flick of a switch caters for the output of an electric or acoustic guitar. Halo signal indicators help with maintaining correct levels. Red indicates a clipping signal, and with reduced gain the lights will momentarily turn amber before returning to green.

A large monitor dial provides control over the output level being sent to monitor speakers, while a high-quality amplifier provides a clean yet loud signal to headphones. A direct monitor switch routes audio directly from the inputs to both the headphone and speaker outputs, allowing for zero-latency monitoring. The included Scarlett Plug-In suite provides EQ, compression, gate and reverb processing, and is cross-platform compatible with all major DAWs.

Light and compact portable interface that easily fits in a laptop bag
Two Focusrite microphone preamps (same design as those on the Saffire PRO 40 and Liquid Saffire 56)
Excellent digital performance with 24-bit resolution at sample rates of up to 96KHz
Rugged anodized aluminum unibody chassis provides protection against the harsh environment of the road
Bus powered - no need of an additional power supply
Includes Ableton Live Lite 8 software, as well as the company's Scarlett plug-in suite providing EQ, compression, gate and reverb and compatible with all major DAWs
Gain knobs with surrounding halo indicators for each input (red indicates a too hot signal)
Direct monitor switch on the front panel allows for hearing what is being recorded through speakers or headphones, without the signal having to go through the computer (avoids latency)

Dear Mark,

How about Behringer XENYX Q802USB.

Regards,

Sudheer

Hi Sudheer -

The Behringer Xenyx Q802USB Premium 8-Input 2-Bus Mixer is a great little mixer, but it is not a true audio interface for use with your computer.  It will not integrate as smoothly with your DAW and not offer the best performance overall when compared to the Focusrite device I recommended above..

Please contact us via e-mail if you have additional questions:  AskBH@BandH.com

I'm interested in knowing more about the Tascam UH-7000 USB 2.0 Interface.

I hear that it has DSP and includes a compressor, EQ, Reverb, etc., and has superior quality. I would use it strictly for voice recordings.  My concern is: Can you hear

via a headset the compressor, or EQ being tweaked as you are talking and will the final setting be recorded onto a DAW audio track versus adding effects after the recording?  If this is possible it would eliminate having to have another piece of equipment ala channel strip in the chain.  I would like to use a Shure SM7B which the Tascam should have enough output to drive it - I hope.  Look to hear from you regarding this.  Thank you!  Phil

Hi Phil -

You should not need any additional hardware with the Tascam UH-7000 as it's preamp stage will play nicely with the Shure SN7B

Please contact us via e-mail if you have additional questions:  AskBH@BandH.com

Very thorough article.... So, I thought you might be best to answer a question I have not found answered on the web. What could cause a 4 input audio interface to only signal in the first 2 channels? It's connected via usb to an i7 core computer. I've tried changing cables, mikes, instruments, skipping inputs, changing power options... the last 2 input channels just don't register sound in the Adobe flash media live encoder 3.2 but the interface unit does indicate that it registers sound. Got any ideas?

Hi Gato -

The solution may be very straightforward once we know more about your set-up. Let us know what OS and version you are using; interface brand and model; and the drivers you have installed. Please e-mail us at the address below:

Hi Author of this great article. I hope you can help me here. I have a M-Audio interface (Fast Track). I also have Guitar rig software. Every this is working fine when I use the headphone connection of the M-Audio interface (I mean I can hear clear sound when using head phone connection of M-Audio interface). I mean sound is very clear and OK through head phone of the interface. But when I use the RCA cable connected to studio monitor it does not sound good (through there is sound but it's very low).

I checked every set up but can't help. Can you please tell me how could I get a clear sound in my monitors through the studio monitor speakers.

Kind Regards

Raj

Hi Raj -

The interface offers very little gain for the monitors.  Make sure your cables are intact and not damaged and the volume is adjusted on your active monitors.

I was just wondering if anyone might know why I am not able to hear my recording at all unless I have my audio interface hooked up?  I recorded something earlier with my keyboard via audio interface.....then later tried to listen to it with just my laptop's built-in speakers and wasn't able to hear a thing (my software even notified me that I wouldn't be able to hear it unless I connected my audio interface).  Is there any way I could change it to where I can hear it on my laptop too?  I even tried exporting the song to a file and tried to play it and got nothing.  Thanks so much to anyone who helps!

Hi Hayl -

This is not an unusual occurrence with older versions of ProTools and other DAWs.  Please contact the manufacturer of your interface and/or DAW for details and a possible work around.

Nice article and info on audio interfaces, and very helpful..

Recording guitar through a Line6 UX1 interface to computer and it has just 1/4" TRS/TS jacks for connecting in to it.. And in this endeavor, I find it would be useful to connect one of the Analog outs on the audio interface (line6 UX1) to the computer's sound card which has those S/Pdif ins/outs and they are easily selectable in the software controls, to use for whatever, like monitoring the guitar sound, hopefully without latency. So I'm wondering which S/Pdif connector/patch cable to use for meshing in with the UX1 to computer. The sound card on this computer is a SoundBlaster X Fi

The only other way to do that without latency (in my recent experience), is using the Mic input which is 3.5mm jack on the back of the sound card/ rear of computer, and setting the line/mic on the software controls for the sound card to "mic" rather than "line" and then the monitor dial on the audio interface will work right and there isn't any latency at all. But I want to try the S/Pdif connector instead since it is supposed to be better sounding than the 3.5mm mic input on the computer sound card, but will need the correct S/Pdif cable with a connection that can go in a 1/4 jack on the recording interface. There is a /stereo monitor in/ on the UX1 but it hasn't put out any sound to the computer so far when connecting like the analog outs have done on the UX1, using my current equipment the way it is..

Hi Dan -

Consider using this device for the conversion you are proposing:

The GTV-DD-2-AA GefenTV Digital Audio Decoder from Gefen accepts audio encoded in Dolby Digital (at up to 5.1 channels) from your multi-channel S/PDIF or TOSLINK digital audio source and converts it to L/R analog audio. It allows you to listen to digital audio sources, such as DVD & CD players or digital computer audio, on your legacy analog sound system. Plug-and-play installation means no special configuration or software are required.

You will need cables as well:

The HPR-003X2 Dual 1/4" TS Male to Dual RCA Male Stereo Audio Cable (3') from Hosa Technology is a professional audio cable that is ideal for touring and live sound applications where a device with stereo unbalanced 1/4" outputs needs to be connected to a device with stereo RCA phono inputs. The cable has top-quality REAN connectors for excellent durability and superior signal transfer.

3/6/14 Don't know if this is still viewed, but just got a Steinberg Sequel 3 prgram and need an audio interface.  this was extremely helpful.  would an electci guitar be considered mic level or line level, no power or effects on the guitar, at least initially.  Effectds in he loop would definately bump it up to line level, correct?  Once again, thanks a lot for the useful complete primer on this digital stuff, Mark

Hi Mark -

A guitar is considered "Low-Z" and interfaces usually offer this input for guitars and other insrtruments.  It is not a Mic or a Line output

The UR22 from Steinberg is a two input, two output USB 2.0 audio interface that features dual D-PRE microphone preamps coupled with 24-bit/192 kHz converters. The portable device is housed in an all metal chassis and also functions as a MIDI interface, allowing for connection of external MIDI devices. With a dedicated high- impedance switch, a separate headphones jack and phantom power supply, the unit is perfect for mobile musicians, touring DJs, or the small personal writing studio.

A Hi-Z switch on input two allows for direct recording of electric guitar or bass without the need of a DI box. Latency-free hardware monitoring is available and a Mix knob allows for blending the direct signal and the output of the host. Independent headphones and main output controls provide for adjusting the monitor and phones level individually.

Hi Gary -

The AudioBox 22VSL from PreSonus is a portable 2 input/2 output USB 2.0 audio and MIDI interface that allows for monitoring with low-latency effects. It features two combo microphone/instrument inputs with Class-A XMAX microphone preamps, and ships with Studio One Artist DAW software.

The compression, limiting, semi-parametric EQ, high-pass filter, reverb, and delay effects are the same as found on the company's StudioLive 16.0.2 mixer. Additionally, the AudioBox Virtual Studio- Live "kernal mode" cuts monitoring latency to under 2 1/2 milliseconds, which is virtually inaudible.

The unit is USB bus-powered and housed in a ruggedly built, metal chassis. Phantom power can be switched globally. Clip lights are provided for both channels

Hi,

I just bought an M-Track M Audio with 2 inputs, which means I can use 2 equipments simultaneously. Oh, and it also has MIDI input and output. I mainly use it for vocals and guitar. From my computer, when I plug in my interface, it detects 2 input sources, mono1, and mono2. So there's no problem there if I want to sing and play my guitar simultaneously.

However, if say, I want to connect a drum or a keyboard using MIDI input, can my computer track all three of the inputs at the same time? or should I just have to do it the old school way, by recording it one by one? I'd search for the info far and wide but still can't get the answer.

First off, thanks for a great article. I hope I can get some answers regarding 1. How to get my speaker monitors to hook up to my computer, 2. How to hook up home recording for keyboard, vocal, guitar?.
I have Mac Pro and mac book. I have studio monitor speakers-BUT they require power source, they are studio monitor speakers that require Pre amp power, ( any pre amp recommendations please) so what piece of equipment needed to go from monitor speakers>Pre amp>??>??>?? Mac book . This set up would be for " core audio", so I can edit audio thru various audio editors (peak, adobe audition, GarageBand, etc) and be sble to listen to playback through monitor speakers. Second set up would be one say to record electric guitar via amp>??>??>??>mac? So I mic the guitar amp then run mic XLR cable to>??>??>> to get sound of amp recorded thru speakers via mac book? I really enjoy shopping at B and H so I just started to read some of the tutorials.

Please advise

Thank you

Здравствуйте! Помогите пожалуйста с выбором саундкарты или интерфейса! У меня программа"Samplitude Musik Studio MX" на ноутбуке Asus в Vista! Мне необходимо записывать аранжировки с кейборда Roland G-70 Workstation,чтобы сохранялись теже звуки. Плюс записывать инструменты и голос с конденсаторных и со студийных микрофонов ! Что бы Вы мне посоветовали ? Я заранее благодарен ! Так как в технических параметрах не силён ! Знаю только про Usb2! И что саундкарты работают не со всеми программами .Еще раз спасибо!с уважением Александр .

Hello! Help please with the choice soundcard or interface! I program "Samplitude Musik Studio MX" on the Asus in Vista! I need to write arrangements with keybord Roland G-70 Workstation, saved to cover those sounds. Plus record instruments and voice with condenser and with studio microphones! What would you advise me? I am thankful in advance! Since the technical parameters is not strong! I only know about Usb2! And that saundkart not work with all programs. Thanks again! Respectfully Alexander.

Very good article finally, a great read. I learnt many things.

I bought a Shure microphone (PG58) for recording vocals but realised I need an audio interface to link the output to macbook pro. I have Sony STRDH820 AV receiver, wondering if it can work as audio interface? If yes, how I set it up? As it seems it doesn't have an XLR input.

I do not have big budget at this beginning stage to spend on an expensive audio interface. My aim is to set-up a home studio. If the answer to above Q is no, could you suggest if iRig microphone interface (under 20 quid), ll maintain the quality of my shure microphone when connected to macbook.

Thanks

Hi ! Sorry to bother hopefully I can get this issue solved. I have a Scarlett 2i2 and when all set up with mic and headphones I can hear sound from mic but not sounds from the computer, like the instrumental of the song or any computer sound for that matter! Also: I messed around with setting on both DAW and interface as well as computer sound (widows7) earlier to get rid of latency. first I couldn't get the latency regardless of direct monitor switch. Now I got the latency to stop but now I can't hear nothing through the headphones except sound of mic only when the direct monitor switch is on! In off position I can't hear a sound!! Any ideas please???!

Sorry for asking a dumb question, which this probably is. I'm trying to use Battery 3 as a stand-alone percussion synth via a new Dell E6540 with Haswell CPU, only 2 weeks old. I'm using Alesis TriggerIO modules to trigger the sounds, and I have long response latencies between trigger and sound output. Would I be better going to an external interface using MIDI rather than USB and the laptop's CPU? The processor is i7-4800MQ 2.7GHz, 2701 Mhz, 4 core, 8 logical processors. I've seen posts claiming to get latencies down to 3msec, mine are > 20msec. They seem obvious to me. Any suggestions? I don't need much of any function at this point other than (I'm guessing here) an external module that can run as sound card for Battery via computer, load and execute the sounds quickly without waiting for the computer's CPU to take action. So, it would likely have MIDI in and contain a good sound processor and of course, outputs. Any suggestions would be greatly appreciated.

My computer crashed and I updated it with a Giggabyte Z77X-UP4TH (thunderbolt) motherboard. I am using an EMU 1616 interface which works fine with analog mics but I have a Neumann TLM 103 Digital Mic that now cannot be seen by the EMU. I had to re-install the drivers from the EMU 1616M since the 1616 is not serviced anymore by EMU. I think this is why I can't get the EMU to see the Neumann. If I need to get a new interface (I only record vocals and guitars separately)what would be the best interface that would work with my system. I use Samplitude software.
Thanks for any help.

This is a great article.
I have an Aardvark Q10 which does not have Windows 7 drivers. Can you suggest a replacement audio interface with similar or better specifications?
I look forward to your suggestions.
Kevin

Fantastic article... I have a few questions about the Focusrite Scarlett 8i6.

1) Looking @ the unit, I only see 4 inputs... Where are the other 4?

2) When connecting a hardware synthesizer, should it be connected to the preamp-(mic inputs) or the line-level inputs on the rear panel? I've asked several sources and some advised connecting it to the mic-level inputs & others advised connecting it to the line level in's.

Thank you!
