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 addition, 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 convenience -- 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 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.
