Bug 156

Summary: Add function to define a raw sample for application-generated audio

Description Patrice Mandin 2006-03-07 13:48:13 UTC 
SDL_mixer is meant to be a generic API to mix fx samples and music, but
there are two things in it that are missing (from my pov):

- the ability to define raw samples (i.e. not necessarily in one of
supported sample formats, like wav, aiff, voc, etc..): it just needs a
function where you pass a pointer to sample start, length, freq, format.

- the ability to play fx samples at the freq of the audio device,
whatever the fx freq is (i.e. specially when not a multiple of audio
device freq), like playing a 15KHz sample on a 48KHz device.

You mean something like Mix_QuickLoad_RAW()?
The only difference here is that Mix_QuickLoad_RAW() assumes you've already converted the audio data to the output format, which IMHO is a good assumption - either you have pre-converted the data for efficiency, or your data is already all in the same format and you've opened the mixer with that format.
