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 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.
