GarageBand became available on iPad earlier this year, and today Apple extended the portability options to iPhone and iPod touch as well.

As with its larger-screen sibling, the iPhone version uses the Multi-Touch interface to eliminate the need for creators and remixers to have any previous musical instrument experience. Among the instruments that can be digitally played are keyboards, guitars, drums and basses, along with a library of chords.

The device’s built-in microphone lets users add voices or any other acoustic sound, and there are digital effects for those who have an electric guitar to plug in. GarageBand can handle up to eight separate tracks in one musical project.

“GarageBand on iPad has been a big hit and we think customers will love using it on their iPhone or iPod touch,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “The innovative Multi-Touch interface combined with Smart Instruments makes it easy to create great sounding music, even if you’ve never studied music or played an instrument before.”

GarageBand 1.1 for iPad, iPhone and iPod touch is available on the App Store for $4.99, or as a free update to anyone who already bought the iPad version.
