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.
