mkunfilter
mkunfilter is a simple Perl script to create an impulse response that has the inverse frequency response of the one given. It was originally created for a technique in room impulse response measurement.
Usage:
1 | perl mkunfilter.pl original.wav reverse.wav 500 4 |
The third argument is the output length in samples, and the fourth is the maximum gain on any given frequency band. Due to noisy inputs, precision issues, and the fact that frequencies can drop out, it is vitally important that the maximum gain be set to a reasonable value.
