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 3):
The multi-channel decoder of  claim 1 , in which the filter processor is operative to calculate filter coefficients for two filters for each channel of the downmix channel without using the gain factor and to filter the downmix channels and to gain adjust subsequent to filtering the downmix channel.
