SDL_!MixAudio?
NAME SYNOPSIS DESCRIPTION SEE ALSO
SDL_!MixAudio?- Mix audio data
#include
void SDL_!MixAudio?(Uint8 *dst, Uint8 *src, Uint32 len, int volume);
This takes two audio buffers of the playing audio format and mixes them, performing addition, volume adjustment, and overflow clipping. The volume ranges from 0 - 128, and should be set to SDL_MIX_MAXVOLUME for full audio volume. Note this does not change hardware volume. This is provided for convenience -- you can mix your own audio data.
