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 |
摘要 |
<p>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.</p> |
