ABSTRACT:
A scheme has been devised for retrieving audio from a digital audio tape (DAT) that has been used in a device such as a digital audio logger wherein audio is recorded on a intermittent basis. An audio bit map is created on the DAT that represents a record of activity with a "1" bit representing audio and a "0" bit representing absence of audio. The channels of the logger can be searched for a next message or previous message. A predetermined sequence of "1's" and "0's" are used in the search for identifying a message.
