Abstract

An interface for playing back a previously recorded audio digital data stream to a signal processing Personal Computer (PC) adapter card is described. Each recording algorithm provides speech data in fixed-length records. It cannot be assumed that all algorithms use the same record length, but the structure of each record is the same. Some implementations will allow the record length for a particular algorithm to be configured. The interface supplies a buffer via which speech data is transferred. This buffer is made up of a number of blocks, and each block of a number of records.
