Yes, I understand "2" now. I have tried various settings by modifying your code snippet to make it better. For example 3740 Hz is a Little bit better in my view. 3700 Hz sounds a Little "Donald Duckish". I need to experiment with resampling the audio and filtering it before trying to invert. It is s...

I understand the code line except the number "2" after mult. Please explain!

OK, so you implemenetd my hardware solution in code - clever. It sounds pretty good. One can fiddle around with filter edges and LO fx, but it should be good. I will try te other files I have got. Thanks a million. Have to read up more on the lisp syntax...

I have some very old audio files with Soviet cosmonauts talking in inverted spectrum voice. I used to have an analog device that did the unscrambling but it no longer exists. I understand that by inverting the sign of every second sample the spectrum will be inverted. Has anyone ever developed an ad...
