This is fed to a parametric stereo decoder (207) which processes the stereo signal in accordance with extracted parametric stereo data.

A stereo decoder (200) receives the encoded data from the encoder (100).

The stereo decoder generates a set of stereo output channels (C1, C2) in response to a parametric audio input including signal parameters (S1) and stereo related parameters (X1).

A controlled oscillator used in a stereo decoder for synchronizing the oscillatory output to a pilot signal.

Because of unwanted frequency changes, a sampling rate converter precedes the stereo decoder.
