Recording
You'll find apps such as RoboVox and My BeatBox that pitch-shift your singing or turn it into a virtual rhythm machine. Options such as Sonic Loops help you build tunes and backgrounds from loops and samples. Still more, such as S Mixer, provide onscreen multitrack mixers that accept input from other apps. Full-fledged digital recorders such as S Multitrack use interfaces that support drag-and-drop editing to make the most of touchscreen capabilities. Before you head into the studio or out on a mobile gig, upgrade your memory card with a higher-capacity version to accommodate the audio data you create.
