Bug 1356

Summary: SDL_mixer uses SDL_MixAudio
Product: SDL_mixer Reporter: Dag Ågren <paracelsus>

Description Dag Ågren 2012-01-01 13:32:14 UTC 
The function SDL_MixAudio has this note in the documentation:

Note: Do not use this function for mixing together more than two streams of sample data. The output from repeated application of this function may be distorted by clipping, because there is no accumulator with greater range than the input (not to mention this being an inefficient way of doing it). Use mixing functions from SDL_mixer, OpenAL, or write your own mixer instead.

This seems entirely reasonable. However, SDL_mixer still seems to use this function for all its mixing despite it being documented to not be suitable for this purpose (and SDL_mixer itself being recommended as an alternative!)
