For the inner composer in you, Sonoma Wire Works created a new iPhone application that allows you to record music anywhere. The process is as easy as sliding the record button to the right, belting out lyrics and hitting the stop button. With its clever interface, the four-track recorder allows you to execute a full harmony by recording one track while listening to the other three, and the WiFi compatibility makes it so you to upload your jam to any computer in WAV format in just about five minutes. Revolutionizing portable music production, FourTrack is a guaranteed hit.
You can purchase the application through the iTunes store for $10.
