Analog Channel from McDSP is a pair of plug-ins that emulates the sounds of high-end analog tape machines, analog tape, and analog channel amplifiers. With the experience of modelling analog compressors and filter circuits, both vintage and modern, McDSP has provided a solution for smoothing the digital edge that can sometimes accumulate on digital workstations as track count increases.
One section of the Analog Channel, AC101, acts as a "digital pre-amp" allowing even excessive amounts of gain without digital distortion. A drive control determines where the audio "sits" in the saturation/compression region, and even the attack and release times of the distortion character are adjustable.
The second section, AC202, provides standard tape machine parameters such as bias, playback speed, and IEC1/2 equalization. However, it also provides controls well beyond the limits of analog tape devices, including adjustable low frequency roll off and head bump - independent of playback speed. The user can select from several playback head types, and even control the rate at which tape saturation is dis-engaged. Modern and vintage tape formulations are available.
Analog Channel HD v5 plug-in provides TDM functioning for Pro Tool HD, but also includes an Audio Units version for use with DAWs that support the format, including Logic, Digital Performer (DP) and Ableton Live. Additionally, a third party software application that supports the TDM, RTAS, or AudioSuite plug-in standard can also be used.
