I'm thinking GarageBand is a little over kill for simple recording. How about trying a simple recorder program like "Audio Recorder". It fires up and simply starts recording to an audio file, whatever audio input device you've selected. You can select raw AIFF audio files or MP3 encoding on the fly. Available at: http://versiontracker.com/dyn/moreinfo/macosx/17392 > A) what format to save it to in order to burn a cd. If you are wanting to burn a CD, you can of course use iTunes. Now if you have lots of space, record it in the correct CD format and iTunes won't have to convert it. Select the raw AIFF 44.1 Khz stereo. But for limited space, you can select the MP3 format for recording, pick your quality level, and then add it to the iTunes library. When itunes is to burn an AUDIO CD, it will expand it back to raw uncompressed audio on the disk. You can store lots of recordings in mp3 with iTunes. Keep in mind however, that you'll want to stop the recording every hour, so the file can fit on one CD. If you want to make an MP3 CD, then you can burn more than one hour on a disk. You could then burn several lectures on a single CD. This would only play on a MP3 capable CD player or computer of course. > B) What size of file will it be if it's an hour and a half to two hour > talk Depends on the selected quality level and Mono/Stereo settings. Lower quality, smaller file.

The issue is going to be the acoustics of the room. Recording with the internal microphone, 10-20 feet away from the speaker, won't sound very good. It would serve you better to have an externally wired microphone placed within a few feet of the speaker and plugged into the mac input to record. If this is not possible, at least set the iBook on the table in front of the speaker, or sit as close as you can. That will do more for making the recording sound better, than the setting of the software, which can be set as high quality as you want. > Most important, since my hard drive is only 10 gb, can I install GB on > my 15 gb iPod and run it off of there (connected to the iBook, of > course)? There's another option, get the voice recorder device from Griffin that turns your iPod into a recorder.
