SDL_BuildAudioCVT(3)
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.
