Abstract

An innovative recording and playback system to record and play back audio conferences. In one embodiment, the audio recorded during the conference is digitized and placed in blocks of a determined size. These blocks are stored on a computer storage medium such as a disk drive. A data structure is maintained consisting of an identification of the number and location of the voice blocks. Also provided in the data structure is the identification and location of blocks of data corresponding to the conference participants as well as the identification of other information associated with the conference. When the conference is to be played back by the user, the data structure and corresponding blocks are accessed to play back the conference as well as selectively provide the additional information, for example, the spoken names of the conference participants, to the user.
