Abstract:
1. Method to generate multiple output audio channels (y 1 , . . . yM) from two microphone generated audio channels (x 1 , x 2 ), in which the number of output channels is equal or higher than two, the method comprising: determining, using a device embedding a processor, directions of sound components related to microphone characteristics; determining, using the device embedding a processor, compensation gains of sound components related to the microphone characteristics such that upon application of the compensation gains to sound components, sound components are picked up with one of a same gain and approximately the same gain within a desired range of directions; and generating, using the device embedding the processor, the output audio channels, y wherein a gain of the microphone generated audio channels is modified as a function of direction of arrival according to the compensation gains.
