SDL_AudioSpec

A structure that contains audio data. This structure (function in header) is called when the audio device needs more data.

Syntax

void (SDLCALL* callback)
     (void*    userdata, 
      Uint8*   stream, 
      int      len);
void* userdata

stream	a pointer to the audio data buffer
len	the length of that buffer in bytes

int	freq	DSP frequency -- samples per second
SDL_AudioFormat	format	audio data format
Uint8	channels	number of channels: 1 mono, 2 stereo
Uint8	silence	audio buffer silence value (calculated)
Uint16	samples	audio buffer size in samples (power of 2)
Uint16	padding	necessary for some compile environments
Uint32	size	audio buffer size in bytes (calculated)

The calculated values in this structure are calculated by SDL_OpenAudio().

Once the callback returns, the buffer will no longer be valid.

Stereo samples are stored in a LRLRLR ordering.
