APPARATUS AND METHOD FOR COMPRESSING A SET OF N BINAURAL ROOM IMPULSE RESPONSES |
摘要 |
An apparatus and a method for compressing a set of N binaural room impulse responses, BRIR, wherein each channel of an N channel audio signal is convolved with the corresponding compressed set of N BRIR. The apparatus may comprise at least one analyzing and compressor module adapted to separate an input binaural room impulse response signal into a first binaural signal set provided to the binauralization processing of the initial part of the BRIR (early part) and a second binaural signal set provided to the binauralization processing of the final part of the BRIR (late part) via a downmix module; a binauralization module adapted to obtain a binaural signal based on convolving the N channel audio signal with the first binaural signal set and the second binaural signal set. |
