Abstract:
The present invention relates to audio coding systems which make use of a harmonic transposition method for high frequency reconstruction (HFR). A system and a method for generating a high frequency component of a signal from a low frequency component of the signal is described. The system comprises an analysis filter bank providing a plurality of analysis subband signals of the low frequency component of the signal. It also comprises a non-linear processing unit to generate a synthesis subband signal with a synthesis frequency by modifying the phase of a first and a second of the plurality of analysis subband signals and by combining the phase-modified analysis subband signals. Finally, it comprises a synthesis filter bank for generating the high frequency component of the signal from the synthesis subband signal.

Claim (Index 5):
The system according to  claim 1 , further comprising:\n an upsampler for performing an upsampling of the low frequency component to yield an upsampled low frequency component; an envelope adjuster to shape the high frequency component; and a component summing unit to determine a decoded audio signal as the sum of the upsampled low frequency component and the adjusted high frequency component.
