Audio::APE(3)

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

SYNOPSIS
        use Audio::APE;
        my $mac = Audio::APE->new("song.ape");

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

        my $macTags = $mac->tags();

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

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

The information returned by Audio::APE is keyed (for different MAC versions) by:

Version 3.97 or earlier: Flags => {
            MONKEY_FLAG_8_BIT
            MONKEY_FLAG_WAV_NOT_STORED
            MONKEY_FLAG_24_BIT
            MONKEY_FLAG_SEEK_ELEMENTS
            MONKEY_FLAG_PEAK_LEVEL
            MONKEY_FLAG_CRC
        },
    SampleRate    : sample rate of uncompressed data in Hz (usually 44100)
    startHeaderInfo    : offset for header info
    compression    : compression scheme (string)
    Channels    : Mono or Stereo
    streamVersion    : Monkey's Audio version used for compression
    TotalSamples    : calculated total samples in file
    bitRate    : bitrate in bps
    duration    : duration of track in seconds
    fileSize    : filesize in bytes
    filename    : filename with path
    BlocksPerFrame    : number of blocks in a frame (usually 73728)

Version 3.98+ adds the following:
    Flags    : reserved for later (not the same as 3.97)
    DescriptorBytes    : Size of v3.98+ Descriptor block
    Bits    : bits per sample (usually 16)

CONSTRUCTORS

•   new( $filename )

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

INSTANCE METHODS

•   info( [$key] )

    Returns a hashref containing information about the Monkey's Audio 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 Monkey's Audio 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.
