Use iTunes3 to extract hidden tracks from songs Apps
In iTunes 3, you can cut up songs by setting the start and end times. Start by control-clicking a song, choose Get Info from the contextual menu, then go to the Options tab and choose a start and end time and hit OK. Next, from the Advanced menu, select "Convert selection to MP3." iTunes will make a new song (leaving the old intact) based on your chosen start and end times. This is great for those tracks that contain two songs.

[robg adds: I used this trick to split apart two or three of those silly "hidden bonus track" songs -- you know the ones with five minutes of silence and then the hidden song starts? Now, finally, I have the hidden song as a 'normal' song without having to fast-forward through the silence. This hint saves a trip to and from QuickTime Pro to accomplish the same result, which I was usually too lazy to do!]

This function can also be used to separate tracks from ripped audio streams (Streamripper ).

After setting your Start and Stop times, use the AppleScript Quick Convert to select an encoder on the fly, without having to go to Preferences; the script will restore your original encoder after the conversion.

If you do so, does the qualitiy of the mp3 stay the same or is it reduced because of decoding/re-encoding?

Good question. After examining the original file and a smaller one that I created from it, all seems OK -- no loss. The original was a 1:59/2.2 MB (Finder says 2391486 bytes) at 160 kbps. The shorter one is 1:00/1.2 MB (1203264 in Finder) at 160 kbps.

That doesn't make sense, though...does it? :\

Oh yes, there will be degradtion. The severity of it, however, may be a matter of taste. I would use this method on spoken word audio, for example.

I dunnoabout that, which is one of the reasons i split the mp3 file , rather than re-encoding. Although, in fairness, i have no idea if it is de/recoding, but hey, who needs audio degredation? :)

a bit of overkill, but hey, works great

MP3 is similar to JPG formats, which are lossy. Hence why you will not convert all your mp3s to mp4 when the time comes to load up your ipod with 100000 songs. :)

For what its worth...

...here is a script that will make a copy of the selected track using your current MP3 encoder settings, using the track's Start and Stop times as the beginning and end of the new track. Your mileage will vary. You will have to set Start and Stop manually.

Does this re-encode the already-mp3'd data, or does it just split the track in two? I know that Audion has a little mp3 editor that is for the express purpose of this sort of abuse, which does not re-encode the data - it just cuts it up at the level of the individual chunks of encoded sound; I've used it in the past to chop blank space out of 'hidden tracks'.

It re-encodes. However, if you re-encode at the same bit rate you're not losing anything -- or at least, not much more -- because any filterable audio has already been filtered at that bit rate. It's like re-straining the spaghetti in the collander. You don't get less spaghetti and you don't strain more water.

If you re-encode at a higher bit rate, you will likewise see no advantage. If you re-encode at a smaller bit rate, you will filter more audio.

If you re-encode an MP3 as an MP4 you will definetly get some garbage because the two use different compression methods.

Here's a spec on MPEG. http://isc.faqs.org/faqs/mpeg-faq/part1/

Fantastic! Now I can finally cut out the narrative introduction to Michael Jackson's I Just Can't Stop Loving You. Now don't knock it. His Bad album is really great, but every time that song starts (whispering: "I just want to touch you for a while") it makes me want to puke :)

This was submitted as a hint, but seems better as a comment here...
There was an earlier hint to shorten the length of a track in iTunes by converting it. If you have a track that's 5 minutes, let's say, and 15 minutes of silence (like a hidden track), the previous hint suggested choosing "Get Info" on the track, Changing the Stop Time under the "Options" tab, and then converting the track. When you convert, the new track is the new length you chose, leaving out the clutter.

Messing around today, I found that the same trick works directly from CD imports. Just choose "Get Info" before you import a CD track, and make your changes. When the track is imported into iTunes, the shortened version is what you'll get.

I've been using this with imports from CDs happily for a while. One thing I'm interested in is if there is any way to set multiple start and end times, so as to just cut out some middle silence or whatever but keep the result as one track. Of course this is easy enough with QT Pro but it would be cool to have within iTunes - it would also be easy enough if iTunes would allow 'Join CD Tracks' for the resulting .mp3s or whatever as well.
