| Description: |
I got tired of other scripts/etc which took info from CDDB and
failed to rip a CD into MP3's. So I wrote up my own scripts!
The first one (wscd2wav) gets the CDDB info, uses cdparanoia,
and puts the .wav into it's own directory, setting a symlink
for each one. The second one (scan4wav2mp3) looks for the
symlinks, reads where the .wav is, and uses lame on the .wav.
So far it's working very well.
To use, open up two xterms (or use splitvt or screen) and
change into the directory you want the MP3's to go to in
both. Run wscd2wav in the first, scan4wav2mp3 in the second.

### Some of this code came from CHOAD (especially the CDDB handler)
### Modules
use CDDB;
### Stuff
my $HOME = $ENV{HOME};
my $USER = $ENV{USER};
my $HOST = `hostname`; $HOST =~ s/\n//;
$currcd=0;
while(!$done) {
### Check the CDDB info on this person.
my(@toc,$ntracks,$i);
$i=0;
open(IN,"cdparanoia -Q 2>&1 |") || die $1;
while(<IN>) {
chomp;
if(/^\s*(\d+)\.\s+\d+\s+\[\d+:\d+\.\d+\]\s+\d+\s+\[(\d+):(\d+)\.(\

### Now get CDDB...
my $cddb = new CDDB( Host => "freedb.freedb.org",
Port => 888,
Login => "$USER\@$HOST",

my ($cddb_id, $track_numbers, $track_lengths, $track_offsets,

$artist = $1; $album = $2;
my $disc_info = $cddb->get_disc_details($genre, $cddb_id);
@tracks = @{$disc_info->{'ttitles'}};
}
### Work out the prefixes...
$prefix = "$artist/$album";
$prefix =~ tr/ ,.\'\"&//d;
system "mkdir -p $prefix";
for($i=0; $i<$ntracks; $i++) {
$f=$tracks[$i];

print "$t>$fname\n";
system "cdparanoia $t $fname.wav";
symlink "$fname.wav", "$currcd-$i.trk";
}
system "eject -r /dev/hdc";
$currcd++;
print "Pausing...";
<STDIN>;
}
scan4wav2mp3:
#!/usr/bin/perl
print "Scanning for MP3's...\n";
while(1)
{
sleep 10;
opendir(DIR,".");
@d=grep {/\.trk$/} ( readdir(DIR) );
