§The
inverse filter can be either pre-convolved with the test signal or post-convolved with the result of the measurement
§Pre-convolution usually reduces the SPL being generated by the loudspeaker, resulting in worst S/N ratio
§On the other hand, post-convolution can make the background noise to become “coloured”, and hence more perciptible
§The resulting anechoic IR becomes almost perfectly a Dirac’s Delta function:
