id3v2

MP3::Tag::ID3v2 is a Read / Write ID3v2.x.y tags from mp3 audio files.

SYNOPSIS

MP3::Tag::ID3v2 supports * Reading of ID3v2.2.0 and ID3v2.3.0 tags (some ID3v2.4.0 frames too) * Writing of ID3v2.3.0 tags

MP3::Tag::ID3v2 is designed to be called from the MP3::Tag module.

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

# read an existing tag
$mp3->get_tags();
$id3v2 = $mp3->{ID3v2} if exists $mp3->{ID3v2};

# or create a new tag
$id3v2 = $mp3->new_tag("ID3v2");

See MP3::Tag for information on the above used functions.

* Reading a tag

$frameIDs_hash = $id3v2->get_frame_ids(truename);

foreach my $frame (keys %$frameIDs_hash) {
my ($name, @info) = $id3v2->get_frame($frame);
for my $info (@info) {
if (ref $info) {
print "$name ($frame):n";
while(my ($key,$val)=each %$info) {
print " * $key => $valn";
}
} else {
print "$name: $infon";
}
}
}
* Adding / Changing / Removing / Writing a tag
$id3v2->add_frame("TIT2", "Title of the song");
$id3v2->change_frame("TALB","Greatest Album");
$id3v2->remove_frame("TLAN");
$id3v2->write_tag();
* Removing the whole tag
$id3v2->remove_tag();
* Get information about supported frames
%tags = $id3v2->supported_frames();
while (($fname, $longname) = each %tags) {
print "$fname $longname: ",
join(", ", @{$id3v2->what_data($fname)}), "n";
}

Audio::TagLib::ID3v2::SynchData is a Perl module with a few functions for ID3v2 synch safe integer conversion.

SYNOPSIS

use Audio::TagLib::ID3v2::SynchData;

print Audio::TagLib::ID3v2::SynchData->toUInt(
Audio::TagLib::ByteVector->new("11")), "n"; # got 6321
print Audio::TagLib::ID3v2::SynchData->fromUInt(6321)->data(), "n";
# got "11"

In the ID3v2.4 standard most integer values are encoded as "synch safe" integers which are encoded in such a way that they will not give false MPEG syncs and confuse MPEG decoders. This namespace provides some methods for converting to and from these values to ByteVectors for things rendering and parsing ID3v2 data.
UV toUInt(ByteVector $data)

This returns the unsigned integer value of $data where $data is a ByteVector that contains synchsafe integer. The default length of 4 is used if another value is not specified.

ByteVector fromUInt(UV $value)

Returns a 4 byte (32 bit) synchsafe integer based on $value.

EXPORT

None by default.

ID3V2.3 library is a library written in C to provide read and write access to ID3 tags.

ID3V2.3 library is designed to be very easy to use, and is meant to be compiled directly into your project. You can only access the most commonly used tag fields.

The source code is easy to read and well documented.

Example:

#include "genre.h"
#include "lib_id3v1.h"

main()
{
id3Tag tag;

strcpy (tag.artist, "Myartist");
strcpy (tag.album, "Myalbum");
strcpy (tag.title, "Mysong");
strcpy (tag.track, "12");
strcpy (tag.year, "2002");
strcpy (tag.comment, "Mycomment");
strcpy (tag.genre, "Mygenre");

set_id3v2tag(&tag, "/home/sam/myfile.mp3");
}

If you need more info, look into the header file, its really simple.

Audio::TagLib::ID3v2::RelativeVolumeFrame is an ID3v2 relative volume adjustment frame implementation.

SYNOPSIS

use Audio::TagLib::ID3v2::RelativeVolumeFrame;

my $i = Audio::TagLib::ID3v2::RelativeVolumeFrame->new(
Audio::TagLib::ByteVector->new(""));
$i->setChannelType("MasterVolume");
print $i->channelType(), "n"; # got "MasterVolume"

This is an implementation of ID3v2 relative volume adjustment. The presense of this frame makes it possible to specify an increase in volume for an audio file or specific audio tracks in that file.

Multiple relative volume adjustment frames may be present in the tag each with a unique identification and describing volume adjustment for different channel types.

new()

Constructs a RelativeVolumeFrame. The relevant data should be set manually.

new(ByteVector $data)

Constructs a RelativeVolumeFrame based on the contents of $data.

DESTROY()

Destroys the RelativeVolumeFrame instance.

String toString()

Returns the frames identification.

see identification()

LIST channles()

Returns a list of channels with information currently in the frame.

NOTE This should be a list of PV which indicates the ChannelType.

see %_ChannelType

PV channelType()

Always returns master volume.

deprecated

void setChannelType(PV $t)

This method no longer has any effect.

deprecated

IV volumeAdjustmentIndex(PV $type = "MasterVolume")

Returns the relative volume adjustment "index". As indicated by the ID3v2 standard this is a 16-bit signed integer that reflects the decibils of adjustment when divided by 512.

This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.

see setVolumeAdjustmentIndex()

see volumeAjustment()

void setVolumeAdjustmentIndex(IV $index, PV $type = "MasterVolume")

Set the volume adjustment to $index. As indicated by the ID3v2 standard this is a 16-bit signed integer that reflects the decibils of adjustment when divided by 512.

By default this sets the value for the master volume.

see volumeAdjustmentIndex()

see setVolumeAdjustment()

< NV volumeAdjustment(PV $type = "MasterVolume") >

Returns the relative volume adjustment in decibels.

NOTE Because this is actually stored internally as an "index" to this value the value returned by this method may not be identical to the value set using setVolumeAdjustment().

This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.

see setVolumeAdjustment()

see volumeAdjustmentIndex()

void setVolumeAdjustment(NV $adjustment, PV $type = "MasterVolume")

Set the relative volume adjustment in decibels to $adjustment.

By default this sets the value for the master volume.

NOTE Because this is actually stored internally as an "index" to this value the value set by this method may not be identical to the one returned by volumeAdjustment().

see setVolumeAdjustment()

see volumeAdjustmentIndex()

PeakVolume peakVolume(PV $type = "MasterVolume")

Returns the peak volume (represented as a length and a string of bits).

This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.

see setPeakVolume()

setPeakVolume(PeakVolume $peak, PV $type = "MasterVolume")

Sets the peak volume to $peak.

By default this sets the value for the master volume.

see peakVolume()

%_ChannelType

This indicates the type of volume adjustment that should be applied. keys %Audio::TagLib::ID3v2::RelativeVolumeFrame::_ChannelType lists all available values used in Perl code.

MP3::Tag::ID3v2-Data can get_frame() data format and supported frames.

SYNOPSIS

$mp3 = MP3::Tag->new($filename);
$mp3->get_tags();
$id3v2 = $mp3->{ID3v2} if exists $mp3->{id3v2};

($info, $long) = $id3v2->get_frame($id); # or

($info, $long) = $id3v2->get_frame($id, raw);

This document describes how to use the results of the get_frame function of MP3::Tag::ID3v2, thus the data format of frames retrieved with MP3::Tag::ID3v2::get_frame().

It contains also a list of all supported ID3v2-Frames.

get_frame()
($info, $long) = $id3v2->get_frame($id); # or

($info, $long) = $id3v2->get_frame($id, raw);

$id has to be a name of a frame like "APIC". See also L id3v2> id3v2> .

The names of all frames found in a tag can be retrieved with the L id3v2> id3v2> function.

ID3v2ChapterTool is an application which allows you to author and embed chapter information in your MP3 files. ID3v2 Chapter Tool project is part of the BBC open source initiative and is maintained as a Sourceforge project.

The application uses a new signalling specification that has been developed by ID3.org which is supported by APIs created in this project. These build on the Java ID3 API developed by Jens Vonderheide.

Chapters in this context could be any of the following:

- chapters within an audiobook
- articles within a podcast
- individual tracks within a multi-track audio file

At the most basic level this chapter information consists of the start time of each chapter you define, allowing listeners to skip easily to these points in the file during replay. However, chapters can also have descriptive information (e.g. title), images and URLs.

The information attached to each chapter can be used by media players to provide a dynamic display during replay. For example, the images attached to each chapter can be used to provide a slide show.

The ID3v2ChapterTool also allows you to create a Table of Contents (TOC).

At the most advanced level it is possible to define multiple TOCs for a single audio file. For example, one TOC could provide access to the entire audio file whilst a second TOC could provide access to a set of highlights.

Once chapter information is widely supported by media players it will enable some exciting new multimedia applications such Audio Encyclopaedias.
