Abstract
A codec for wideband 12kHz speech and audio in a video conferencing application is proposed in this paper. The codec in based on warped linear predictive coding algorithm which utilizes the auditory Bark frequency resolution. The structure of the codec is described and the main issues on the real-Time implementation are discussed. The codec is integrated to a video conferencing product which is a video codec PC-board. The algorithm is implemented in a Texas TMSC31 digital signal processor.
