How to run deinvert

To descramble a WAV file (input.wav) that was scrambled with simple inversion:

./src/deinvert -i input.wav -o output.wav -p 4

Deinvert comes with a set of frequency presets; these can be selected with the -p switch.

If you want to use it for split-band scrambling, you will need to provide two frequencies: The inversion carrier and the split point.

./src/deinvert -i input.wav -o output.wav -f 3500 -s 1200

Here, the inversion carrier was 3500 Hz and the split point is at 1200 Hz.
