harmonic vector excitation (HVXC)

Harmonic Vector Excitation (HVXC) is a speech-optimized parametric speech compression technique that operates at 8 kHz and produces data rates from 2 kbit/s

to 6 kbit/s. In this highly efficient speech compression, the residual signal from Linear Predictive Coding (LPC) is transformed and then parametrized. In MPEG-4 V.2, the capabilities of HVXC are extended by variable bit rate (VBR). The HVXC process is used in digital broadcasting, among other applications.
