Bug 396

Summary: SDL_mixer documentation does not warn about sample rate.
Product: SDL_mixer Reporter: Nicos <nicosp>
Component: miscAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED DUPLICATE QA Contact: Sam Lantinga <slouken>
Severity: trivial    
Priority: P2    
Version: unspecified   
Hardware: x86   
OS: Other   

Description Nicos 2007-02-21 11:08:22 UTC 
SDL_mixer does not upsample when the chunk sample rate < output sample rate but it incorrectly plays the sample with the output sample rate (from what I can hear). I realize that you might not want to support upsampling but at least it should be mentioned in the documentation and/or make Mix_PlayChannelTimed return an error in this case.
Comment 1 Ryan C. Gordon 2007-02-22 02:23:26 UTC 
It supports upsampling if the sample rates are multiples (so it can do 11025 to 22050 or 44100, but not 8000 to 11025).

The cause of this issue is actually a bug in SDL and not SDL_mixer, which incorrectly resamples the audio without reporting an error.

As such, I'm marking this bug as a duplicate of that issue.
