Apache::MP3 is a Perl module that can generate streamable directories of MP3 and Ogg Vorbis files.

SYNOPSIS

# httpd.conf or srm.conf
AddType audio/mpeg mp3 MP3
AddType audio/playlist m3u M3U
AddType audio/x-scpls pls PLS
AddType application/x-ogg ogg OGG

# httpd.conf or access.conf
< Location /songs >
SetHandler perl-script
PerlHandler Apache::MP3
< /Location >

# Or use the Apache::MP3::Sorted subclass to get sortable directory listings
< Location /songs >
SetHandler perl-script
PerlHandler Apache::MP3::Sorted
< /Location >

# Or use the Apache::MP3::Playlist subclass to get persistent playlists
< Location /songs >
SetHandler perl-script
PerlHandler Apache::MP3::Playlist
< /Location >
A demo version can be browsed at http://www.modperl.com/Songs/.

This module makes it possible to browse a directory hierarchy containing MP3, Ogg Vorbis, or Wav files, sort them on various fields, download them, stream them to an MP3 decoder like WinAmp, and construct playlists. The display is configurable and subclassable.

NOTE: This version of Apache::MP3 is substantially different from the pre-2.0 version described in The Perl Journal. Specifically, the format to use for HREF links has changed. See Linking for details.

Apache::MP3::L10N is a base class for Apache::MP3 interface localization.

This module is the base class for generating language handles (via Locale::Maketext) which Apache::MP3 (and subclasses) use for presenting their interface.

To localize this for your language of choice, see the source for Apache/L10N/fr.pm for an example lexicon that should contain all the English phrases, and an example French translation.

For example, if youre localizing this to Swahili, youd copy Apache/L10N/fr.pm to Apache/L10N/sw.pm (since I18N::LangTags::List tells us that sw is the language tag for Swahili), and change its package Apache::MP3::L10N::fr; line to package Apache::MP3::L10N::sw;, and then youd replace all the French phrases that are the values in %Lexicon with Swahili phrases.

For example, youd change:

fetch => sauvegarder,

to:

fetch => lete,

if you considered "lete" (from the infinitive "kuleta", haul) to be a good translation of the English "fetch" in that context.

qndmp3 (the Quick and Dirty MP3 Player) is a Perl-based console MP3 player-frontend with playlist support. In the future this file will be more informative.

MP3::Info is a Perl module that can manipulate / fetch info from MP3 audio files.

SYNOPSIS

#!perl -w
use MP3::Info;
my $file = Pearls_Before_Swine.mp3;
set_mp3tag($file, Pearls Before Swine, q"77s",
Sticks and Stones, 1990,
q"(c) 1990 77s LTD.", rock & roll);

my $tag = get_mp3tag($file) or die "No TAG info";
$tag->{GENRE} = rock;
set_mp3tag($file, $tag);

my $info = get_mp3info($file);
printf "$file length is %d:%dn", $info->{MM}, $info->{SS};
my $mp3 = new MP3::Info $file;
$mp3->title(Perls Before Swine);
printf "$file length is %s, title is %sn",
$mp3->time, $mp3->title;

$mp3 = MP3::Info->new(FILE)

OOP interface to the rest of the module. The same keys available via get_mp3info and get_mp3tag are available via the returned object (using upper case or lower case; but note that all-caps "VERSION" will return the module version, not the MP3 version).

Passing a value to one of the methods will set the value for that tag in the MP3 file, if applicable.

use_mp3_utf8([STATUS])

Tells MP3::Info to (or not) return TAG info in UTF-8. TRUE is 1, FALSE is 0. Default is TRUE, if available.

Will only be able to turn it on if Encode is available. ID3v2 tags will be converted to UTF-8 according to the encoding specified in each tag; ID3v1 tags will be assumed Latin-1 and converted to UTF-8.

Function returns status (TRUE/FALSE). If no argument is supplied, or an unaccepted argument is supplied, function merely returns status.

This function is not exported by default, but may be exported with the :utf8 or :all export tag.

use_winamp_genres()

Puts WinAmp genres into @mp3_genres and %mp3_genres (adds 68 additional genres to the default list of 80). This is a separate function because these are non-standard genres, but they are included because they are widely used.

You can import the data structures with one of:
use MP3::Info qw(:genres);
use MP3::Info qw(:DEFAULT :genres);
use MP3::Info qw(:all);

remove_mp3tag (FILE [, VERSION, BUFFER])

Can remove ID3v1 or ID3v2 tags. VERSION should be 1 for ID3v1 (the default), 2 for ID3v2, and ALL for both.

For ID3v1, removes last 128 bytes from file if those last 128 bytes begin with the text TAG. File will be 128 bytes shorter.

For ID3v2, removes ID3v2 tag. Because an ID3v2 tag is at the beginning of the file, we rewrite the file after removing the tag data. The buffer for rewriting the file is 4MB. BUFFER (in bytes) ca change the buffer size.

Returns the number of bytes removed, or -1 if no tag removed, or undef if there is an error.

set_mp3tag (FILE, TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE [, TRACKNUM])

set_mp3tag (FILE, $HASHREF)

Adds/changes tag information in an MP3 audio file. Will clobber any existing information in file.

Fields are TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE. All fields have a 30-byte limit, except for YEAR, which has a four-byte limit, and GENRE, which is one byte in the file. The GENRE passed in the function is a case-insensitive text string representing a genre found in @mp3_genres.

Will accept either a list of values, or a hashref of the type returned by get_mp3tag.
If TRACKNUM is present (for ID3v1.1), then the COMMENT field can only be 28 bytes.

ID3v2 support may come eventually. Note that if you set a tag on a file with ID3v2, the set tag will be for ID3v1[.1] only, and if you call get_mp3tag on the file, it will show you the (unchanged) ID3v2 tags, unless you specify ID3v1.

get_mp3tag (FILE [, VERSION, RAW_V2])

Returns hash reference containing tag information in MP3 file. The keys returned are the same as those supplied for set_mp3tag, except in the case of RAW_V2 being set.
If VERSION is 1, the information is taken from the ID3v1 tag (if present). If VERSION is 2, the information is taken from the ID3v2 tag (if present). If VERSION is not supplied, or is false, the ID3v1 tag is read if present, and then, if present, the ID3v2 tag information will override any existing ID3v1 tag info.

If RAW_V2 is 1, the raw ID3v2 tag data is returned, without any manipulation of text encoding. The key name is the same as the frame ID (ID to name mappings are in the global %v2_tag_names).

If RAW_V2 is 2, the ID3v2 tag data is returned, manipulating for Unicode if necessary, etc. It also takes multiple values for a given key (such as comments) and puts them in an arrayref.

If the ID3v2 version is older than ID3v2.2.0 or newer than ID3v2.4.0, it will not be read.

Strings returned will be in Latin-1, unless UTF-8 is specified (use_mp3_utf8), (unless RAW_V2 is 1).

Also returns a TAGVERSION key, containing the ID3 version used for the returned data (if TAGVERSION argument is 0, may contain two versions).
get_mp3info (FILE)

Returns hash reference containing file information for MP3 file. This data cannot be changed. Returned data:

VERSION MPEG audio version (1, 2, 2.5)
LAYER MPEG layer description (1, 2, 3)
STEREO boolean for audio is in stereo

VBR boolean for variable bitrate
BITRATE bitrate in kbps (average for VBR files)
FREQUENCY frequency in kHz
SIZE bytes in audio stream
OFFSET bytes offset that stream begins

SECS total seconds
MM minutes
SS leftover seconds
MS leftover milliseconds
TIME time in MM:SS

COPYRIGHT boolean for audio is copyrighted
PADDING boolean for MP3 frames are padded
MODE channel mode (0 = stereo, 1 = joint stereo,
2 = dual channel, 3 = single channel)
FRAMES approximate number of frames
FRAME_LENGTH approximate length of a frame
VBR_SCALE VBR scale from VBR header
On error, returns nothing and sets $@.

MP3::Tag is a Perl module for reading tags of MP3 audio files.

SYNOPSIS

use MP3::Tag;

$mp3 = MP3::Tag->new($filename);

# get some information about the file in the easiest way
($title, $track, $artist, $album, $comment, $year, $genre) = $mp3->autoinfo();
$comment = $mp3->comment();

# or have a closer look on the tags

# scan file for existing tags
$mp3->get_tags;

if (exists $mp3->{ID3v1}) {
# read some information from the tag
$id3v1 = $mp3->{ID3v1}; # $id3v1 is only a shortcut for $mp3->{ID3v1}
print $id3v1->title;

# change the tag contents
$id3v1->all("Song","Artist","Album",2001,"Comment",10,"Top 40");
$id3v1->write_tag;
}

if (exists $mp3->{ID3v2}) {
# read some information from the tag
($name, $info) = $mp3->{ID3v2}->get_frame("TIT2");
# delete the tag completely from the file
$mp3->{ID3v2}->remove_tag;
} else {
# create a new tag
$mp3->new_tag("ID3v2");
$mp3->{ID3v2}->add_frame("TALB", "Album title");
$mp3->{ID3v2}->write_tag;
}

$mp3->close();

Apache::MP3::Playlist can manage directories of MP3 files with sorting and persistent playlists.

SYNOPSIS

# httpd.conf or srm.conf
AddType audio/mpeg mp3 MP3

# httpd.conf or access.conf
< Location /songs >
SetHandler perl-script
PerlHandler Apache::MP3::Playlist
PerlSetVar SortField Title
PerlSetVar Fields Title,Artist,Album,Duration
< /Location >

Apache::MP3::Playlist subclasses Apache::MP3::Sorted to allow the user to build playlists across directories. Playlists are stored in cookies and are persistent for the life of the browser. See Apache::MP3 and Apache::MP3::Sorted for details on installing and using.

mp3cue cuts an input MP3 file according to the information stored in a .cue file (for example multiple tracks of DJ mix), and writes the output to multiple MP3 files.

poc is a mp3 and ogg streamer supporting following protocols:

HTTP (mp3 and ogg)
RTP (RFC 2250) (mp3 only)
RTP (RFC 3119) (mp3 only)
homegrown FEC protocol (mp3 only)

It should work under any POSIX platform, and does not require any additional library. You need a C99 compiler though.

poc is still beta software, ipv6 and ogg support was not tested extensively.

poc includes mp3cue, a mp3 CUE cutter, and mp3cut, a mp3 command-line editing tool.
