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.
