Three-dimensional audio scene binauralization/transauralization method for e.g. audio headset, involves filtering sub band signal by applying gain and delay on signal to generate equalized and delayed component from each of encoded channels
Three-dimensional audio scene binauralization/transauralization method for e.g. audio headset, involves filtering sub band signal by applying gain and delay on signal to generate equalized and delayed component from each of encoded channels
The method involves filtering through equalization-delay, and a sub band signal by applying gain and delay on the signal to generate an equalized and delayed component from each of encoded channels. A subset of equalized and delayed signals is added to create a number of filtered signals in a transformed domain. Each of the filtered signals is synthesized by a synthesis filter to obtain a set comprising reproduction sound channels of a number higher than or equal to two sound reproduction channels in time domain. Independent claims are also included for the following: (1) a device for sound spatialization of an audio scene (2) a computer program for executing filter, addition and synthesizing steps.
