Implementation of a real-time HY-2 channel vocoder algorithm
Timothy S. Loos · 2002
This paper describes the proprietary implementation of a real-time software based HY-2 compatible channel vocoder algorithm. The HY-2 algorithm was used prior to linear predictive coding (LPC) vocoders for low bit rate voice communications at 2400 bps. This implementation is a unique and instructive implementation of a parametric vocoder, producing high quality speech.
