NAME

       Audio::CD - Perl interface to libcdaudio (cd + cddb)

SYNOPSIS

         use Audio::CD ();
         my $cd = Audio::CD->init;

DESCRIPTION

       Audio::CD provides a Perl interface to libcdaudio by Tony Arcieri, available from
       http://cdcd.undergrid.net/

       Several classes provide glue for the libcdaudio functions and data structures.

            my $cd = Audio::CD->init;

       stat
           Stat the Audio::CD object, returns an Audio::CD::Info object.

            my $info = $cd->stat;

       cddb
           Returns an Audio::CDDB object.

            my $cddb = $cd->cddb;

       play
           Play the given cd track (defaults to 1).

            $cd->play(1);

       stop
           Stop the cd.

            $cd->stop;

       pause
           Pause the cd.

            $cd->pause;

           Resume the cd.

            $cd->resume;

       eject
           Eject the cd.

            $cd->eject;

       close
           Close the cd tray.

            $cd->close;

            $cd->play_frames($startframe, $endframe);

       play_track_pos
            $cd->play_track_pos($strarttrack, $endtrack, $startpos);

       play_track
            $cd->play_track($strarttrack, $endtrack);

       track_advance
            $cd->track_advance($endtrack, $minutes, $seconds);

       advance
            $cd->advance($minutes, $seconds);

       get_volume
           Returns an Audio::CD::Volume object.

            my $vol = $cd->get_volume;

       set_volume
            $cd->set_volume($vol);

Audio::CDDB Class

       discid
            my $id = $cddb->discid;

       lookup
           Does a cddb lookup and returns an Audio::CD::Data object.

            my $data = $cddb->lookup;

Audio::CD::Data Class

       artist
            my $artist = $data->artist;

       title
            my $title = $data->title;

       genre
            my $genre = $data->genre;

       tracks
           Returns an array reference of Audio::CD::Track objects.

            my $foo = $data->tracks($info);
            my @tracks = @$foo;

Audio::CD::Track Class

       name
            my $name = $track->name;

Audio::CD::Info Class

       mode
           Returns the CD mode, one of PLAYING, PAUSED, COMPLETED, NOSTATUS;

            my $track = $info->mode;
            print "playing" if $info->mode == Audio::CD::PLAYING;

       present
           Returns true if a disc is present.

            $cd->play if $info->present;

       current_track
           Returns the current track number being played or paused.

            my $track = $info->current_track;

       first_track
           Returns the number of the first track on the CD.

            my $track = $info->first_track;

       total_tracks
           Returns the total number of tracks on the cd.

            my $track = $info->total_tracks;

       track_time
           Returns the current track play time:

            my($minutes, $seconds) = $info->track_time;

       time
           Returns the current disc play time:

            my($minutes, $seconds) = $info->time;

       length
           Returns the disc length time:

            my($minutes, $seconds) = $info->length;

       tracks
           Returns an array reference of Audio::CD::Info::Track objects.

            my $foo = $info->tracks;
            my @tracks = @$foo;

Audio::CD::Info::Track Class

       length
           Returns the track length time:

            my($minutes, $seconds) = $tinfo->length;

       pos Returns the track position on the CD:

            my($minutes, $seconds) = $tinfo->pos;

       type
           Returns the track type (either TRACK_AUDIO or TRACK_DATA):

            if ($tinfo->type == Audio::CD::TRACK_AUDIO) {
              print "audio track\n";
            } elsif ($tinfo->type == Audio::CD::TRACK_DATA) {
              print "data track\n";
            }

       is_audio
           Returns true if the track is an audio track; equivalent to the test:

            $tinfo->type == Audio::CD::TRACK_AUDIO ? 1 : 0

       is_data
           Returns true if the track is a data track; equivalent to the test:

            $tinfo->type == Audio::CD::TRACK_DATA ? 1 : 0
