NAME¶
SDL_BuildAudioCVT - Initializes a SDL_AudioCVT structure for conversion
SYNOPSIS¶
#include "SDL.h"
int SDL_BuildAudioCVT(
SDL_AudioCVT *cvt, Uint16
src_format, Uint8 src_channels, int src_rate, Uint16 dst_format, Uint8
dst_channels, int dst_rate);
DESCRIPTION¶
Before an
SDL_AudioCVT structure can be used to convert audio data
it must be initialized with source and destination information.
src_format and
dst_format are the source and destination format of
the conversion. (For information on audio formats see
SDL_AudioSpec).
src_channels and
dst_channels are the number
of channels in the source and destination formats. Finally,
src_rate
and
dst_rate are the frequency or samples-per-second of the source and
destination formats. Once again, see
SDL_AudioSpec.
RETURN VALUES¶
Returns
-1 if the filter could not be built or 1 if it could.
