What, if anything, are you guys using to post-process the audio from sdtrunk to make it sound better?
sdrtrunk on a P25 system works great but the audio it outputs is the raw IMBE decoded audio without any sort of post processing. Despite listening on a very nice set of desktop speakers (Audioengine A2), the audio from sdtrunk qualitatively sounds worse than the Unication G5 on my desk. I'm pretty sure this is because the speaker on the G5 is naturally removing a lot of the low and high ends from the audio and the resulting EQ makes voices more intelligible. The G5 might also be doing some audio processing or EQ in software, I'm not sure.
To improve the audio from sdrtrunk, I would really like to pipe it through something that could do a couple things:

- Apply an EQ to improve intelligibility of voices
- Apply some sort of audio AGC/compression/normalization to try to normalize the level across different talk groups/radios/users
