How could I go about converting aif (or is it aiff?) to Mp3 or wma?
I want a small song file size and also it has to be WMA or mp3 to work on my zen. Could I change it so Garageband would export projects to iTunes as mp3s?
Use iTunes.
Have mp3 selected for importing in the prefs, choose your bitrate and use the option in the Advanced menu that says Convert selected files to MP3.
