Abstract:
A multi-channel decoder for generating a binaural signal from a downmix signal using upmix rule information on an energy-error introducing upmix rule for calculating a gain factor based on the upmix rule information and characteristics of head related transfer function based filters corresponding to upmix channels. The one or more gain factors are used by a filter processor for filtering the downmix signal so that an energy corrected binaural signal having a left binaural channel and a right binaural channel is obtained.

Claim (Index 14):
The multi-channel decoder of  claim 1 , in which the filter processor is operative to combine HRTF filters associated with two channels by adding weighted or phase shifted versions of channel impulse responses of the HRTF filters, wherein weighting factors for weighting the channel impulse responses is of the HRTF filters depend on a level difference between the channels, and an applied phase shift depends on a time delay between the channel impulse responses of the HRTF filters.
