Python Audio Tools 2.10 (Default branch)
11-19-2008
Python Audio Tools is a collection of audio handling programs that work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more. It supports internationalized track filenames and metadata using Unicode. It works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from FreeDB or FreeDB-compatible servers. Audio formats supported are WAV, FLAC, WavPack, MP3, Ogg Vorbis, M4A, and more. License: GNU General Public License v2 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
