"The FourTrack app (iTunes link) is the work of Sonoma Wire Works, which makes the desktop recording software RiffWorks, and The Retronyms, which makes Recorder, the top-selling single-track recording software in the App Store. After a few days of pre-release testing, we've seen that this is a solid, functional app, well worth the $10 asking price for musicians and anyone else who messes around with audio, despite -- or even because of -- its rudimentary, four-track-like functionality. It's stable, easy to use and useful."

"[Record four tracks] at 16bit, 44.1kHz...unlimited in length, until your iPhone is full. The interface shows meters for recording and playback levels, recording clip lights, faders for each channel, and pan controls. FourTrack also features a Compressor and Limiter, latency compensation and Wi-Fi sync so you can get your recordings off your iPhone or iPod. [Sonoma Wire Works] said future versions of FourTrack will include integration with its RiffWorks [Mac & Windows] software. Development on the integration is already underway."

"A lot can be done with four tracks, and using the FourTrack'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!"
