A friend of mine, posted this on his blog, and I thought I'd share it. With his permission, here's a nice computer tip, dealing with MP3 encoding:

Someone asked about Apple's AAC music compression settings, so I thought I'd post this general tip on MP3 compression.
Although I don't have an Apple anything, I did try an experiment awile back with MP3s.
I took one song I know well, and compressed an original .WAV version of it (a non-compressed windows version) into an MP3 file with different settings. 96, 128, 16, 320 etc. Made sure also I set the ID3, and filename with these numbers so I could tell them apart. Then tried them on my stereo, the car's stereo, headphones, and the computer's stereo (I had a 5.1 computer stereo system then. Now it's dead :)
I found that around 96 or so, it sounded very close to the original. This only works on me, because of my hearing. Others may find it'd take 320 (CD quality) to match the original. Or others may be happy with as low as 16, depending on the person.
On the flip side, if you have things like podcasts, speechs, old-time radio shows (shows done in the 1920s - 1960s on the radio), and other things like that. Things that quaility doesn't really matter. Then you may be able to get even more compression out of them. OTR can be compressed to 16 without problems. I can get hundreds of 30 minute shows, compressed at 16, on one CDR, and you can barely notice any difference in quality.
The best bet, try a few settings on test equipment first, then just burn the rest at the settings you like.

Shado and I have a love of old-time radio shows. That's how we first met; on an IRC chat room dealing with OTR. He's got a good collection, he shares with me.
