Originally created by @androos on GitHub (Jul 9, 2018).

RNNoise = off
Noise Suppression = off
Max. Amplification set to almost any value higher than 1.00

Tested using a hiss sound. The sound disappears after a few seconds.
Also sound quality is noticeably reduced specially on higher values.

The effect vanishes completely when Max. Amplification = 1.00

See #3323.

If you compiled Mumble, you can try to bypass the Speex preprocessing by replacing
github.com/mumble-voip/mumble@e21ff8596e/src/mumble/AudioInput.cpp (L836-L843)

with

psSource = psMic;

@davidebeatrici doing that does result in a noticeably more well-rounded sound, but also appears to kill the noise reduction?
