Decrease gain of outputs as a result of gain changes on some input

Question asked by arkashkin on Nov 25, 2015

Hi,

 

I need to create a ducking feature for an audio device.

There are 4 audio inputs on the system and 4 audio outputs, which outputs exactly same audio which came from the inputs.

In addition, there is a special microphone input. Only when a person talk to microphone, I want the 4 outputs gain to be decreased, each by a configurable amount.

 

Can some one please explain to me (or provide me a SigmaStudio diagram if possible) which components should I use to achieve such a behavior from my DSP?

 

Thanks in advance.
