SDL_MixAudio- Mix audio data
void SDL_MixAudio(Uint8 *dst, Uint8 *src, Uint32 len, int volume);
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.
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.
