Below are two applescripts that I constructed to convert audio files to Apple Lossless or aac format in iTunes from the desktop using OnMyCommand contextual menu application:
TO-AAC (July 27, 2005)
Here we have a series of command-line executables, some of which I have
compiled myself, for doing various tasks, everything from burning CDs
to putting the computer to sleep:
alac [Command-line program for converting Apple Lossless to wave.]
apeplay [Command-line program for play monkey audio files.]
And finally, a few useful unix scripts:
trash [Moves specified files to OS X trash. Useful replacement for rm.]
weather [Downloads and displays weather information. Set for Eureka, CA.]
