Spectral Invert

This macro “reflects” the frequencies present in a track, such that each frequency becomes “Nf - f”, where “Nf” is the Nyquist frequency (half the sample rate) and “f” is the frequency in the selected audio.
In simple terms, it converts high frequencies to low frequencies, and low frequencies to high frequencies.


  1. When applying to the current project, the project must contain one audio track only
  2. Stereo tracks are mixed down to mono.
