MULTITRACK RECORDING USING MULTIPLE DIGITAL ELECTRONIC DEVICES
First Claim
1. A method for creating a multitrack recording, comprising:
- a) receiving by a digital device a command that establishes the digital device to be a master device for the multitrack recording;
b) transmitting by the master device to an external communication system a signal for an external slave digital device to begin collecting samples;
c) transmitting by the master device to the external communication system a signal for the external slave digital device to begin recording of a single track; and
d) transmitting by the master device to the external communication system a signal for the external slave digital device to stop recording of the track.

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. Slaves may begin preliminary sampling of audio information prior to the start signal, preparing to promptly begin actual track recording. Upon receiving the command to start recording, each slave chooses as first frame that sample closest to the signal to record. The task of stopping recording is typically handled similarly. A recording device may store an indicator for determining the offset of its first frame, facilitating time interpolation of samples in its track. In this way, all audio tracks, for example, might be transformed to a common set of times. The master might also record a track.

21. A handheld digital device, comprising:
-
a) an interface through which the handheld digital device receives a command that establishes it as a slave device for recording a single track in a multitrack recording; b) an interface to a sensor that captures audio or video information; and c) an interface to an external communication system, through which the device receives signals that cause the device to (i) initiate collection of samples received through the interface to the sensor, (ii) start recording of a track, and (iii) stop recording of the track; and d) tangible storage where the device stores samples. - View Dependent Claims (22)

23. A handheld digital device, comprising:
-
a) an interface through which the handheld digital device receives a command that establishes it as a master device for synchronizing a set of devices, a subset of which each record a single track of a multitrack recording; and b) an interface to an external communication system, through which the master device transmit signals for a slave device in the set of devices to (i) initiate collection of samples, (ii) start recording of a track, and (iii) stop recording of the track. - View Dependent Claims (24)
