Abstract :
An implementation of waveform interpolation (WI) applied to wideband speech coding at 4 kbit/s is presented. Listening tests comparing narrowband speech coded using standard coders are presented, with wideband speech coded using WI. Results show a clear preference for wideband speech over narrowband speech coded at an equivalent bit rate.
