Comment (by atomnuker):
Huh, that's odd. The changes which I made to PNS today (at 12:39 UTC,
commit b6cc8ec7ec) brought PNS closer to what it used to be before but
fixed the warbling artifacts at lower frequencies (it's used alot more
now). The changes to the IS which fixed the bug yesterday (1956cfbaedd36)
shouldn't really have done much to the quality at all and I didn't hear a
difference.
74961-g61009a7 is before I made my PNS changes from yesterday, so are you
sure that the last current git master still sounds worse? The PNS commit I
made yesterday did reduce PNS usage too much (before I fixed that today).
Either way, I'll take a listen to what the encoder sounded like before and
try to see if it's better in the current master.
