Audio::TagLib - Read ID3 and other audio metadata with TagLib
use Audio::TagLib; my $taglib = Audio::TagLib.new($path); # Abstract API - aliases for simple fields say $taglib.title ~ " by " ~ $taglib.artist; say "$path has no album field set" unless $taglib.album.defined; # Raw access to all tags in the file (as a list of pairs) .say for $taglib.propertymap.grep(*.key eq 'ALBUMARTIST' | 'ALBUM ARTIST');
Audio::TagLib provides Raku bindings to the TagLib audio metadata library, providing a fast way to read metadata from many audio file formats: mp3, m4a, ogg, flac, opus, and more. See https://taglib.org for more details.
This module uses the C++ interface to TagLib rather than the C bindings. This means installation requires a C++ compiler, but provides the full API rather than the "abstract only" API.
This module is newer than Simple and does not yet provide tag writing functions.
This module does not keep a taglib object open and reads everything into memory initially, meaning there is no
free method needed (unlike Simple).
Audio::Taglib::Simple has a lowercase 'l' in its name, where this module uses
TagLib (as does the official website). I thought adjusting the case was a good idea at the time.
TagLib provides what is known as the "abstract API", which provides an easy interface to common tags without having to know the format-specific identifier for a given tag. This module provides these as attributes of
Audio::TagLib. The following fields are available as strings (Str):
The following are provided as integers (Int):
length - length of the file, in seconds
These attributes will be undefined if they are not present in the file.
The raw tag values are available in the propertymap attribute as a List of Pairs. It is possible to have duplicate keys (otherwise this would be a hash).
If you are looking for a tag that is not available in the abstract interface, you can find it here.
