SDL_MixAudio(3) SDL API Reference SDL_MixAudio(3)NAME
SDL_MixAudio- Mix audio data
SYNOPSIS
#include "SDL.h"
void SDL_MixAudio(Uint8 *dst, Uint8 *src, Uint32 len, int
volume);
DESCRIPTION
This function takes two audio buffers of len bytes each of
the playing audio format and mixes them, performing addi-
tion, volume adjustment, and overflow clipping. The volume
ranges from 0 to SDL_MIX_MAXVOLUME and should be set to
the maximum value for full audio volume. Note this does
not change hardware volume. This is provided for conve-
nience -- you can mix your own audio data.
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 dis-
torted 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.
