Bad audio quality for voice recordings

[zuglufttier]

The audio quality of voice recordings are pretty bad at the moment, sibilants are emphasized way too much.

Which settings/codecs are used right now? WhatsApp sounds more natural in comparison.

Very low bitrate AAC. It should probably be increased.

Something like AAC VBR q5.0 would be perfect, though that might not even be necessary. But using mono would yield small file sizes anyway.

VBR is actually not safe to use with encryption because the variable compression reveals information about the underlying waveform. But yeah, we can probably even double the current bitrate without much network issues.

@chrisballinger Thank you guys for being so picky (really!) - because that's the contributing factor which makes it a real crypto-messenger! :)

Oh, that's interesting to know! Since we don't do real time audio in thod case, just about any setting would do, I guess.
