It is possible to compute just once the following term:

Then, whenever a new set filters is required, this is generated simply applying to R the gains Q of the target microphone:

FIR filters realtime synthesis algorithm:

Thanks to Hermitian symmetry properties, a real-FFT algorithm can be employed
