$20 Turns Your iPhone Into An 8-Channel Audio Recorder


Yudo has introduced Rectools08pro Multi Track Recorder (App Store link), a $20 app that turns your iPhone into an 8-channel audio recorder.

This is pretty amazing, when you consider that The Beatles recorded Sgt. Pepper’s with 4-track recorders! Of course, the iPhone imposes limitations on getting audio in and out; as far as I know, you can only record two channels at a time to the iPhone.

According to Yudo, “We are from now on also planning to make it network compatible, add synthesizers, a drum machine, effects and much more in the near future.”
