[Freeswitch-dev] A question about 16 bit linearisation in mod_conference

[Ghazi Triki]

Hello guys,

I have few questions regarding the 16 bit linearisation in
mod_conference. Especially on those lines
https://github.com/signalwire/freeswitch/blob/master/src/mod/applications/mod_conference/mod_conference.c#L665-L667

1 - What does 16 bit linearisation do? And what it is technically?

2 - Does it have an impact on the mixing quality?

3 - Is it considered as a transcoding, an intermediate encoding between
the input streams and the final output stream?

Thanks
