[jitsi-dev] adjust mic's volumn automatically while making call on Ubuntu


#1

Dear team,

I saw that skype has great feature which can adjust mic's volumn
automatically while making call on Ubuntu. In my experience while using
Jitsi in my PC, mic's volumn has to manually adjust to ~30% the voice is
good, if volumn is about greater than 50% the voice is very bad.

Did Jitsi has the similar that feature like skype has? if yes, how to
enable that feature?

I don't know about Skype. Is that the feature commonly known as automatic gain control (AGC)?

Since you're reporting that you're on Ubuntu, I guess you're using PulseAudio in Jitsi? If the PulseAudio API allows us to enable automatic gain control, we may enable it.

I believe Skype implements it's own AGC by controlling the input gain based on the input signal and simple speech detection (aka voice activity detection).

What Lyubomir was saying is that we don't implement AGC within Jitsi at
this point. The wasapi systrm on Windows does provide this together with th
echo cancellation and if pupse audio has it then you would also have it on
Linux.

We do plan to look at this in the following months tho and we'll probably
take a stab at what the webrtc lib offers.
