SVOPC

SVOPC

SVOPC (ang. Sinusoidal Voice Over Packet Coder) is a lossy speech compression codec designed specifically towards communication channels suffering from packet loss. Operation is quasi-harmonic modeling of the linear prediction residual. SVOPC is used by Skype. It uses more bandwidth than best bandwidth-optimised codecs, but it is packet loss resistant instead.
