Most efficient way to monitor volume of AudioStream?

[leelx78]

Hi @pschatzmann what's the recommended way to monitor the volume of an AudioStream (PCM)? I tried VolumeStream but that seems to be mostly for setting the volume rather than monitoring its output?

Something like a moving average of the signal would work great so that we can use that to detect if there is actual input or noise in the channel, with a time constant.

If I need to write an extension of AudioStream with this feature it's no problem, I just wanted to check with you first before reinventing the wheel :D

Thanks!

The class you are looking for is call VolumeOutput!
