Summary: resampled sound is horrible
Product: Wine
Version: 1.0.0
Platform: All
OS/Version: All
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: directx-dsound
AssignedTo: wine-bugs at winehq.org
ReportedBy: patrakov at gmail.com
The problem is reported because the default sampling frequency in wine (as
configured by winecfg) is 48000 Hz, while apps generally want 44100 Hz.
However, the resampling code in dlls/dsound/mixer.c, function
DSOUND_MixToTemporary(), if I read it correctly, is simply a zero-order hold,
which is completely unacceptable. Even if I don't read it correctly, the
quality is horrible with 48000 Hz and OK with 44100 Hz (tested with MP3 files
in foobar 2000). Please change the resampling method to something more
scientific, e.g., by using libsamplerate.
