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.
