Freshing Equaliser

Freshing Equaliser (Also known in American or Australian English as Freshing Equalizer) is an inverted effect template which the video goes deep pitched which is the opposite pitch of G Major 1, but it was made with the secondary colour correct instead of a HSL adjust.

In Audacity, import your audio file there, then apply the change pitch by setting the pitch from A17 to F17 to make this a -4.00 semitones.

In Kdenlive, import your video file into an appropriate track and also apply the invert first, then use the hue shift effect applied to the video by setting the hue effect 180. Now that you've done that, render the project as a video.
