SDL_MixAudio

This function is a legacy means of mixing audio.

Syntax

void SDL_MixAudio(Uint8 * dst, const Uint8 * src,
                  Uint32 len, int volume);

Function Parameters

dst

the destination for the mixed audio

src

the source audio buffer to be mixed

len

the length of the audio buffer in bytes

volume

ranges from 0 - 128, and should be set to SDL_MIX_MAXVOLUME for full audio volume

Remarks

This function is equivalent to calling

SDL_MixAudioFormat(dst, src, format, len, volume);

where format is the obtained format of the audio device from the legacy SDL_OpenAudio() function.

Code Examples

void MyAudioCallback(void *udata, Uint8 *stream, int len)
{
    extern const Uint8 *mixData;
    SDL_memset(stream, 0, len);  // make sure this is silence.
    // mix our audio against the silence, at 50% volume.
    SDL_MixAudio(stream, mixData, len, SDL_MIX_MAXVOLUME / 2);
}
