GarageBand is a software application for OS X and iOS that allows users to create music or podcasts. It is developed and sold by Apple Inc. on OS X. GarageBand’s music and podcast creation system enables users to create multiple tracks with pre-made MIDI keyboards, pre-made loops, voice recordings, and an array of various instrumental effects. GarageBand can support any sound format except those that are at 8-bits or fewer.
On March 2, 2011, Apple announced a version of GarageBand for the iPad. It has many features similar to the OS X version. Music can be created using the on-screen instruments, which include keyboards, drums, a sampler, and various “smart instruments”. It also acts as a multitrack recording studio with Stompbox effects and guitar amps. Songs can be emailed or sent to an iTunes Library. Additionally, projects can be imported to GarageBand for OS X, where they can be further edited. This also allows instruments from the iOS platform to be saved into the software instrument library on the Mac. The app is compatible with iPhone 3GS or higher, the third generation iPod Touch or higher, and all versions of the iPad, including the iPad Mini. As of version 2.0, the app is free, but requires an in-app purchase for all of the instruments and sounds.
Prior to the launch of Apple’s Mac App Store, GarageBand was only available as a part of iLife, a suite of applications (also including iPhoto, iMovie, iDVD, and iWeb) intended to simplify the creation and organization of digital content, or available on a new Mac. On January 6, 2011, GarageBand was made available independently on the Mac App Store in addition to most of the other applications in the suite.
