Automatic Balance Control

Let me clarify a little since it is not fair to relate it to SA571:

Let SigmaDSP have a two channel input: Lt & Rt.

Both Lt & Rt are connected to a volume control, set, let's say, at mid position.

With an automatic balance control in place, if I increase or decrease the volume of one channel, the other also tracks the first. If one channel is muted, the other also mutes.

So in effect, the two channels are ALWAYS in balance (tracking each other).

I tried using compressors with external detect by criss-crossing the signals to the detect pins, and several other options I could come up with, with no success.

It is possible that I may be missing something obvious. If required, I can post the schematics of all that I tried and we could debug it one by one.

Thanks in advance!!

Hello,

Let me simplify it further:

If I have two audio channels and assume a volume control in one channel, how can I have the other channel track the changes?

Thanks in advance

Hi KKSL,

Sorry I missed this one.

Is this what you're looking to do? (See attached project)

Hello Brett,

No, it is how I have explained here: https://ez.analog.com/message/48168#48168

Sorry, I was not able to put is across correctly.

I need your help on the issue explained in your PM too.

Thanks in advance
