Title:
PARAMETRIC AUDIO CODING
Document Type and Number:
WIPO Patent Application WO2003069954
Kind Code:
A3
Abstract:
The invention provides coding (11) of an at least two-channel audio signal (L,R) by determining common frequencies (f>com<) in the at least two channels (L,R) of the audio signal, which common frequencies occur in at least two of the at least two channels of the audio signal, and by representing respective sinusoidal components in respective channels at a given common frequency by a representation of the given common frequency (f>com<) and a representation of respective amplitudes (A, DELTA A) of the respective sinusoidal components at the given common frequency.
