Perl Audio Converter 4.0.2 (Default branch)
03-17-2008
Perl Audio Converter is a tool for converting multiple audio types from one format to another. It supports AAC, AC3, AIFF, APE, AU, AVR, BONK, CAF, CDR, FAP, FLA, FLAC, IRCAM, LA, LPAC, MAT, MAT4, MAT5, M4A, MMF, MP2, MP3, MP4, MPC, MPP, NIST, OFR, OFS, OGG, PAC, PAF, PVF, RA, RAM, RAW, SD2, SF, SHN, SMP, SND, SPX, TTA, VOC, W64, WAV, WMA, and WV. It can also convert audio from the following video extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, QT, VCD, SVCD, M4V, NSV, NUV, PSP, SMK, VOB, FLV, and WMV. A CD ripping function with CDDB support, batch conversion, tag preservation for most supported formats, independent tag reading/writing, and extensions for Amarok, Dolphin, and Konqueror are also provided.License: GNU General Public License (GPL)Changes:|

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
