Audio::Musepack(3)

NAME
Audio::Musepack - An object-oriented interface to Musepack file information and APE tag fields, implemented entirely in Perl.

SYNOPSIS
        use Audio::Musepack;
        my $mpc = Audio::Musepack->new("song.mpc");

        my $mpcInfo = $mpc->info();

        foreach (keys %$mpcInfo) {
                print "$_: $mpcInfo->{$_}\n";
        }

        my $mpcTags = $mpc->tags();

        foreach (keys %$mpcTags) {
                print "$_: $mpcTags->{$_}\n";
        }

DESCRIPTION
This module returns a hash containing basic information about a Musepack file, as well as tag information contained in the Musepack file's APE tags. See Audio::APETags for more information about the tags.

The information returned by Audio::Musepack->info is keyed by:

        streamVersion
        channels
        totalFrames
        profile
        sampleFreq
        lastValidSamples
        encoder

Information stored in the main hash that relates to the file itself or is calculated from some of the information fields is keyed by:

        trackLengthMinutes      : minutes field of track length
        trackLengthSeconds      : seconds field of track length
        trackLengthFrames       : frames field of track length (base 75)
        trackTotalLengthSeconds : total length of track in fractional seconds
        bitRate                 : average bits per second of file
        fileSize                : file size, in bytes
        filename                : filename with path

CONSTRUCTORS

•   new( $filename )

    Opens a Musepack file, ensuring that it exists and is actually an Musepack stream, then loads the information and comment fields.

INSTANCE METHODS

•   info( [$key] )

    Returns a hashref containing information about the Musepack file from the file's information header.

    The optional parameter, key, allows you to retrieve a single value from the info hash. Returns "undef" if the key is not found.

•   tags( [$key] )

    Returns a hashref containing tag keys and values of the Musepack file from the file's APE tags.

    The optional parameter, key, allows you to retrieve a single value from the tag hash. Returns "undef" if the key is not found.
