SDL_AudioFormat src_format,
Uint8 src_channels,
int src_rate,
SDL_AudioFormat dst_format,
Uint8 dst_channels,
int dst_rate)
Function Parameters
cvt |
A pointer to an SDL_AudioCVT structure that is filled in with audio conversion information. |
src_format |
The source and destination format of the conversion |
src_channels |
The number of channels in the source and destination formats |
src_rate |
The frequency or samples-per-second of the source and destination formats |
dst_format |
The source and destination format of the conversion |
dst_channels |
The number of channels in the source and destination formats |
dst_rate |
The frequency or samples-per-second of the source and destination formats |
Return Value
Returns 0 if the filter could not be built or a strictly positive number if it could.

Remarks
Before an SDL_AudioCVT structure can be used to convert audio data it must be initialized with source and destination information.
For information on audio formats see SDL_AudioSpec.
Currently (SDL-1.2.11) only rate conversions of 2x and (1/2)x with x > 0 are done, nearing the requested rate conversion.
