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 fre- quency 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. EXAMPLES
See SDL_ConvertAudio. SEE ALSO

NAME
SDL::AudioCVT -- Audio Conversion Structure CATEGORY
Core, Audio, Structure SYNOPSIS
DESCRIPTION
The "SDL::AudioCVT" is used to convert audio data between different formats. A "SDL::AudioCVT" structure is created with the "SDL::AudioCVT-"build> function, while the actual conversion is done by the "SDL::Audio::convert_audio" function. METHODS
new This constructor returns an empty "SDL::AudioCVT" structure. build $cvt = SDL::AudioCVT->build( $src_format, $src_channels, $src_rate $dst_format, $dst_channels, $dst_rate ); 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". Currently (SDL-1.2.11) only rate conversions of 2x and (1/2)x with x > 0 are done, nearing the requested rate conversion. See "SDL::Audio::convert_audio". needed Set to one if the conversion is possible src_format Audio format of the source dest_format Audio format of the destination rate_incr Rate conversion increment len Length of the original audio buffer in bytes len_cvt Length of converted audio buffer in bytes (calculated) len_mult "buf" must be "len*len_mult" bytes in size (calculated) len_ratio Final audio size is "len*len_ratio" AUTHORS
