There are nice videos out there on Youtube, but some of them are hard to listen to, because they fall into a frequency region where the tone sounds slightly stressed. An example of such a video is the Clean Code video Core Design Principles for Software Developers by Venkat Subramaniam, which I probably want to lower by 3 or 4 semitones.

So I'm looking for

  • a free (gratis)
  • browser extension (any browser) or other software
  • for Windows
  • that can change the pitch of the voice, i.e. lower the frequency without changing the speed.

I don't want to download and re-encode the video. It should happen on the fly.

This one is really nifty, it can also slow down and loop Youtube vids: Transpose - Pitch - Loop for videos

There's a Chrome extension you could try: Pitch shifter - HTML5 Video audio FX

"Pitch shift the audio in HTML5 videos on any webpage, e.g., YouTube"
