Sonoma Wireworks have released FourTrack, a application for Apple’s iPhone that lets you record and synchronise up to four tracks of audio, without any additional equipment.
A lot can be done with four tracks, and using the application’s GUI, users can start laying down tracks very simply. Just arm a track, slide the Record control, and away you go. In post production, the level of each track can be altered, as can its position in the stereo field, and a compressor/limiter can be used to “automatically fatten the sound of the output mix”. What’s more, your recordings, as 16-bit/44.1kHz data files, can be sent to a wi-fi enabled computer for further editing!
