Abstract: A method and apparatus for multitrack recording of audio information using handheld digital electronic devices are described. Recording of video tracks complementing the audio is also contemplated. One device serves as master; others, slaves. Transmission of start and stop recording signals by the master may facilitate synchronization of the tracks.
