Abstract:
The present invention is a method and apparatus for multitrack recording of audio information using handheld digital electronic devices such as suitably equipped portable digital music players. Recording of video tracks by digital electronic devices to complement the audio is also contemplated. One device serves as a master; the remainder are slaves. A key aspect of the invention is the transmission of start and stop recording signals by the master, which facilitates synchronization of the various tracks. In certain embodiments of the invention, some slaves may begin preliminary sampling of audio information prior to the start recording signal. This prepares these slaves to begin the actual track recording without delay. Upon receiving the command to start recording, each slave chooses as the first frame of its, say, audio track that sample closest to the time the signal to record was received. The task of stopping recording is typically handled similarly. A recording device may store an indicator whereby the time offset of its first frame from the start recording signal can be determined, thus facilitating time interpolation of the samples in its track. In this way, all audio tracks, for example, might be transformed to a common set of time points. In a typical configuration, the master might also record a sound track or a video track.
