Alright, so I was watching a Howard Stern episode when he interviewed Chris Cornell (of soundgarden, temple of the dog, audioslave). Cornell was talking about how he would come up with tunes in his head then have to scramble to record different parts (vocals, guitar, etc) on a ****** recorder so he remembered it. The next day I had this vision of a Garageband Lite (or whatever) on the iPhone. Just something that could record sound in different tracks (of course being recorded one at a time) and perform basic mixing (volume adjustments, panning, some other stuff) just using the built-in microphone. It'd be really basic (obviously) but still a fun app to tool around with. I don't know how good the mic would be for someone playing an acoustic guitar or singing or whatever but assuming that it's comparable to the computer's built-in mics then it'd be alright. I just had a really cool mental picture of like two-three tracks on an iPhone with basic stuff. Not widely useful at all.. I understand that it might not even be worth investing the time to create the software, but I just thought it'd be pretty neat and wanted to share the idea.
