Free convert audio files to ipod software for linux

The Audio File Library provides a uniform and elegant API for accessing a variety of audio file formats, such as AIFF/AIFF-C, WAVE, NeXT/Sun .snd/.au, Berkeley/IRCAM/CARL Sound File, Audio Visual Research, Amiga IFF/8SVX, and NIST SPHERE. Supported compression formats are currently G.711 mu-law and A-law and IMA and MS ADPCM.
Key goals of the Audio File Library are file format transparency and data format transparency. The same calls for opening a file, accessing and manipulating audio metadata (e.g. sample rate, sample format, textual information, MIDI parameters), and reading/writing sample data will work with any supported audio file format. Likewise, the format of the audio data presented to the application need not be like the format of the data contained in the file.
Enhancements:
- libaudiofile/Makefile.am, libaudiofile/audiofile.exports:
- Export only public entry points.
- Released version 0.2.6 of the Audio File Library.

Audio::File is a audio file abstraction library.

SYNOPSIS

use Audio::File;
my $file = Audio::File->new( "foo.bar" );

print "The ". $file->type() ."-file ". $file->name
." is ". int $file->length() ." seconds long.n";

print "Its interpreted by ". $file->tag->artist()
." and called ". $file->tag->title() ".n";

Audio::File abstracts a single audio file, independant of its format. Using this module you can access a files meta-info like title, album, etc. as well as the files audio-properties like its length and bitrate.

Currently only the formats flac, ogg vorbis and mp3 are supported, but support for other formats may be easily added.

FAPG is a tool to generate list of audio files (WAV, MP3, Ogg, etc.) in various formats (M3U, PLS, HTML, etc). It is very useful for quickly creating a playlist of a large number of audio files.

It is coded in C to be as fast as possible, and does not use any specific audio library (like ID3Lib).
This allow you to deploy it faster and easier, and to have better performances since the less informations are loaded.
In the other hand, this tool is not (yet) compatible with all the known formats.

Here are some examples for usage :

Generate a PLS playlist for an album :
fapg --format=pls --output=~/path/to/album/list.pls ~/path/to/album

You have a file server using Samba which shares a large amount of audio files for Windows powered computers using Winamp.
The directory on the server containing the files is "/samba/mp3" and is visible on the Windows network as "serveurmp3" :
fapg --backslash --output=/samba/mp3/list.m3u --prefix=servermp3 --recursive --windows /samba/mp3

An HTML playlist for an album :
fapg --output=fapg.html ~/path/to/album
Here is the result : fapg.html

Perl Audio Converter (PAC) is a tool for converting multiple audio types from one format to another. It supports MP2, MP3, Ogg Vorbis, FLAC, Shorten, Monkey Audio, FAAC (AAC/M4A/MP4), Musepack (MPC), Wavpack (WV), OptimFrog (OFR/OFS), TTA, LPAC, Kexis (KXS), AIFF, AC3, Lossless Audio (LA), AU, SND, RAW, VOC, SMP, RealAudio (RA/RAM), WAV, and WMA.
It can also convert audio from the following video formats/extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, QT, VCD, VOB, and WMV. A CD ripping function with CDDB support, batch and playlist conversion, tag preservation for most supported formats, independent tag reading/writing, and extensions for Konqueror and amaroK is also provided.
Enhancements:
- Added: MP4::Info dependency IO::String to pacpl-install
- Updated: License GPLv3
- Bug Fix: Directory conversions. pacpl was claiming the directory was empty and prompting to use the --recursive option...Thanks to John Meyer for the report.

Audio::TagLib::File is a file class with some useful methods for tag manipulation.

This class is a basic file class with some methods that are particularly useful for tag editors. It has methods to take advantage of ByteVector and a binary search method for finding patterns in a file.

DESTROY()

Destroys this File instance.

PV name()

Returns the file name in the local file system encoding.

Tag tag() [pure virtual]

Returns this files tag. This should be reimplemented in the concrete subclasses.

AudioProperties audioProperties() [pure virtual]

Returns this files audio properties. This should be reimplemented in the concrete subclasses. If no audio properties were read then this will return undef.

BOOL save() [pure virtual]

Save the file and its associated tags. This should be reimplemented in the concrete subclasses. Returns true if the save succeeds.

ByteVector readBlock(UV $length)

Reads a block of size $length at the current get pointer.

void writeBlock(ByteVector $data)

Attempts to write the block $data at the current get pointer. If the file is currently only opened read only -- i.e. readOnly() returns true -- this attempts to reopen the file in read/write mode.

IV find(ByteVector $pattern, IV $fromOffset = 0, ByteVector $before = ByteVector::null)

Returns the offset in the file that $pattern occurs at or -1 if it can not be found. If $before is set, the search will only continue until the pattern $before is found. This is useful for tagging purposes to search for a tag before the synch frame.

Searching starts at $fromOffset, which defaults to the beginning of the file.

This has the practial limitation that $pattern can not be longer than the buffer size used by readBlock(). Currently this is 1024 bytes.

IV rfind(ByteVector $pattern, IV $fromOffset = 0, ByteVector $before = ByteVector::null)

Returns the offset in the file that $pattern at or -1 if it can not be found. If $before is set, the search will only continue until the pattern $before is found. This is useful for tagging purposes to search for a tag before the synch frame.

Searching starts at $fromOffset and proceeds from the that point to the beginning of the file and defaults to the end of the file.

This has the practial limitation that $pattern can not be longer than the buffer size used by readBlock(). Currently this is 1024 bytes.

void insert(ByteVector $data, UV $start = 0, UV $replace = 0)

Insert $data at position $start in the file overwriting $replace bytes of the original content.

This method is slow since it requires rewriting all of the file after the insertion point.

void removeBlock(UV $start = 0, UV $length = 0)

Removes a block of the file starting a $start and continuing for $length bytes.
This method is slow since it involves rewriting all of the file after the removed portion.

BOOL readOnly()

Returns true if the file is read only (or if the file can not be opened).

BOOL isOpen()

Since the file can currently only be opened as an argument to the constructor (sort-of by design), this returns if that open succeeded.

BOOL isValid()

Returns true if the file is open and readble and valid information for the Tag and / or AudioProperties was found.

void seek(IV $offset, PV $p = "Beginning")

Move the I/O pointer to $offset in the file from position $p. This defaults to seeking from the beginning of the file.

void clear()

Reset the end-of-file and error flags on the file.

IV tell()

Returns the current offset withing the file.

IV length()

Returns the length of the file.

BOOL isReadable(PV $file) [static]

Returns true if $file can be opened for reading. If the file does not exist, this will return false.

BOOL isWritable(PV $file) [static]

Returns true if $file can be opened for writing.

%_Position

Position in the file used for seeking. C<<less
