Re: [Savonet-users] [savonet/liquidsoap] Distortion in ALL Opus streams (#759)

[ivellios1988]

Anyway, in `41k_source_output.ogg` the degradation may not be as clearly 
audible - but the distortion is clearly present. It becomes more audible when 
we compare both files in audio editor.

In this attachment: left channel is OPUS (with noticeable hiss), right channel 
is the original file. 
[distortion_comparison.zip](https://github.com/savonet/liquidsoap/files/3142656/distortion_comparison.zip)

And this is what can be seen when we open `41k_source_output.ogg` in editor and 
switch to spectral frequency display:

For comparison, this is the spectral view of the original file:

Just listened to your file @toots - it sounds (and looks) fine:
