A method and apparatus for indicating the time and location at which audio
signals are received by a user-carried audio-only recording device. In one
embodiment, audio signals are received at a receiver of a user-carried
audio-only recording device. A position determining system generates
position information indicative of the location of the portable
user-carried audio-only recording device when the receiver of the portable
user-carried audio-only recording device receives the audio signals. The
audio signals and the position information are stored onto recording
media. The present embodiment integrates the position information with the
audio signals such that alteration of the position information stored on
the recording media results in alteration of corresponding audio input
signals stored on the recording media.
