Abstract

To facilitate fast location of edit-points in a disc-based audio recording system, one or more editing tracks ("spooling" and/of "aux.data") are recorded in conjunction with the digital audio signal ("audio"). The spooling track is a reduced sample rate, reduced bandwidth version of the audio signal. This can be replayed at increased speed to simulate "spooling" on an analogue tape recorder, without exceeding the maximum data reading rate of the disc. The auxiliary data file ("aux data") includes edit markers indicating points in the audio signal. These points are selected by an operator during recording as potential edit points or cue locations. The edit markers can be displayed when the recording is replayed. Preferably a directory of edit markers is also generated, so that a particular edit point can be located quickly. <IMAGE>
