Ideal for podcasts, scripted, or unscripted dialogue, panel discussions, house-of-worship applications, and more, MixAssist Plug-In for MixPre-6 works by intelligently attenuating the gain of microphones that are not in use to reduce unwanted noise, feedback, and comb filter artifacts in multi-microphone applications. The result is a cleaner and more consistent recording. MixAssist automixes post-fade signals to the left and right buses and does not affect the prefade ISO tracks.
Download MixAssist to your computer and move it to your SD card. Insert the SD card in your MixPre-6 and install the plug-in.
Noise-Adaptive Threshold (NAT)
- For each microphone, an ever-changing and automatic threshold is continuously calculated. This per-channel threshold has a slow-attack and very fast decay.
- When an incoming microphone’s signal is instantaneously above this threshold it can be turned on. Steady-state sounds (air conditioning, etc.) will not turn on a microphone—only varying speech-like signals does.
Maxbus
- The envelope of all microphone signals is logically compared together to get the instantaneous peak of the loudest microphone.
- Each microphone envelope is continuously compared to this Maxbus; if the envelope is greater (and it meets the NAT criteria), then it is gated on. If a talker speaks into two or more microphones, it will only gate on one of the microphones, eliminating any comb filtering.
Last Mic Lock-On
- The last used microphone remains on, creating a seamless mix.
Off-Attenuation
- When a microphone is turned off, it does not turn all of the way off, instead it is attenuated by a certain amount, typically 15 dB. This results in a more transparent sound.
Sample Rates and Bit Depths
- You can use MixAssist at sampling rates of 44.1, 47.952, 48, and 48.048 kHz, and at either 24-bit or 32-bit float bit depth.
