Python Audio Tools 2.10 (Default branch)
Image 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:
Support was added for several additional track metadata fields. A program was included for identifying and fixing common metadata problems such as trailing whitespace or empty fields. MP3 encoding was updated to use LAME's 0-9 quality setting instead of named presets. A build error on Mac OS X was fixed. Image

afgetframesize

AFGETFRAMESIZE(3)														 AFGETFRAMESIZE(3)

NAME

       afGetFrameSize - calculate the frame size in bytes for an audio track

SYNOPSIS

       #include <audiofile.h>

       float afGetFrameSize (AFfilehandle file, int track, int expand3to4);

PARAMETERS

       file is a valid AFfilehandle.

       track is an integer which refers to a specific audio track in the file. At present no supported audio file format allows for more than one
       audio track within a file, so track should always be AF_DEFAULT_TRACK.

       expand3to4 is a boolean-valued integer indicating whether frame size calculation will treat 24-bit data as having a size of 3 bytes or 4
       bytes.

DESCRIPTION

       afGetFrameSize returns the number of bytes in a frame in a given audio track.

       A sample frame consists of one or more samples. For a monaural track, a sample frame will always contain one sample. For a stereophonic
       track, a sample frame will always contain two samples, one for the left channel and one for the right channel.

       A non-zero value of expand3to4 should be used when calculating the frame size for storage in memory (since 24-bit audio data is presented
       in memory as a 4-byte sign-extended integer), while a value of zero should be used for calculating storage on disk where no padding is
       added. The parameter expand3to4 is ignored unless the specified audio track contains 24-bit audio data.
