I have not seen anything related to audio compressor in code. It has noise filter, but it is disabled anyway.But it seems to have a brickwall compressor on audio, some time the background noise is too much amplified, Git2P do not like silence or what ? Do you think you can disable this ?
Are you using external mic, or is this git2p internal one? My cam records only loud sounds, and almost does not hear regular speech, and one of yours seems to be pretty sensitive.
What about video quality? Is it youtube, or video really so blocky? Make sure you are using High video quality and B/W effect on, especially in dim light.
