SDL_BuildAudioCVT
Use this function to initialize a SDL_AudioCVT structure for conversion.
Contents
Syntax
int SDL_BuildAudioCVT (SDL_AudioCVT* cvt,
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 format of the audio data; for more info see [SDL_AudioFormat] |
src_channels |
The number of channels in the source |
src_rate |
The frequency or samples-per-second of the source |
dst_format |
The destination format of the audio data |
dst_channels |
The number of channels in the destination |
dst_rate |
The frequency or samples-per-second of the destination |
Return Value
Returns -1 if the format conversion is not supported, 0 if there's no conversion needed, or 1 if the audio filter is set up.

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.
