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.
