I've noticed in many songs, the audio in the nightly has a fairly distorted audio in some sections, especially regarding guitar audio, around the ending reverberations of a note are where it's very noticeable. I can only describe it as an overly "crispy" kind of distortion that's not in stable, and it's definitely unpleasant to the ears when wearing good headphones.
#NIGHTLY: Audio is too "crispy" or distorted

I don't know if anyone else has experienced this or not, but I assume it has something to do with audio engine changes or something since it's not present in the stable branch.
