Abstract

A method is described in which voice algorithm development is reduced by providing a common software interface with the analog hardware. This interface minimizes tuning time by providing a normalized input to the compression routine from all the different analog input devices. In addition, this 'preprocessing' block provides a considerable amount of common function that is required by the voice partition architecture. With appropriate definition the preprocessing block can help reduce the number of instructions that must be processed. In the record function, the preprocessing block provides a common interface to any compression algorithm.
