Artists going all-out on mobile music editing have relatively few options -- GarageBand won't always cut it for the pros. IK Multimedia thinks its newly launched AmpliTube 3.0 could be the solution for those producers on the move. The $20 iOS app introduces a full, multi-track audio editor that can create a final masterpiece. With the help of a guitar rig and customizable drum loop, the suite is theoretically good enough to keep computers out of the studio. Even if musicians don't want to go that far, they may be happy to hear that IK Multimedia has shipped the iRig HD. The $99 interface gives iOS and Mac users a preamped adapter for instruments with quarter-inch plugs. While we're sure some performers would rather stick to traditional recording methods, those who've embraced digital with open arms can check out both AmpliTube and iRig HD at the source links.
