hi again
music playback sounds noisy
for every type I checked ( .mod, .xm, .ogg, .mp3, .mid )
even if I set CD quality parameters
first I thought that was getting 8 bit format set, or 11KHz freq
so I checked with Mix_QuerySpec();
and I got:
44,1KHz freq ( as requested )
AUDIO_S16SYS ( as requested )
2 channels ( as requested )
next I thought that I was using some down sampled music
( those artificial background noices sounds like it was the case )
but no, I play tested everyone of them using other players
and everything sounds fine
so does enybody know why music is so noisy?
any suggestions?

Just a shot in the dark but perhaps you would get better quality by mixing to a higher rate like 96000Hz rather than 44100Hz, some sound drivers will resample your 44100Hz stream to 48000Hz rather
than to a higher rate, and this degrades the sound quality noticeably, but explicitly mixing to a higher rate can resolve the artifacts.
What SDL_AUDIODRIVER is being used? Default or something specific?
What operating system?
You might get better quality by using a different SDL_AUDIODRIVER (for example on some Linux systems pulse is preferred).
This could be the wrong line of debugging though.On 04/07/2012 04:51 PM, apator10 at wp.pl wrote:

No, not really. The resampling actually cannot be noticed if you don’t
feed it killer samples (especially crafted samples that will produce
artifacts.)On 08/04/12 08:19, Forest Hale wrote:
