Pitch shifter - HTML5 Video audio FX
Pitch shift the audio in HTML5 videos on any webpage, e.g., YouTube
# Now fixed for Facebook and YouTube, plugin should handle new videos loading in and changing #
Pitch shifts audio from HTML5 Video sources on a page, without changing the playback rate (unless you want it to).
Potential use cases:
Fixing the voice of a too whiney youtuber.
A satanic version favourite movie clip.
Or a chipmunk remix of a legendary rap song.
Does NOT save any of your data to a remote server.
Does NOT load the pitch shifter on webpage until you enable it (won't needlessly slow your computer down).
Troubleshooting
---------------
If you get no audio from the video it may be that the video is an ad from a different site and the CORS policy prevents us from altering the sound. We're looking at ways of detecting this.

v1.5 8 Feb 2017
- Fixed bug no pitch-shifting bug on Chrome 56. Seems there was an API change/fix so thath AudioParam.setTargetAtTime(target, startTime, timeConstant) required startTime to use the currentTime from the Audio Context, not a relative time (we were using 0).
Change log:
v1.4 15 Feb 2016
- Range of semitones is -24/+24, which gives the same range as the "smooth" option, and is the same range as v1.2
v1.3 12 Feb 2016
- Fix issue with pitch shifting in tones not semitones. Thanks for the bug report guys!
v1.2 27 Oct 2015
- Pitch shift by semi-tones, experimental feature. Change mode using select box between classic smooth and new semi-tones.
- Fix bug where playback rate was not persisted when a video changed.

I've been using this extension for a long time. One of the BEST pitch shifting extensions I've ever used. There's no audio glitches or anything other than the other pitch shifting extensions, it's all smooth sailing for this extension. It's been four years since you guys updated this legendary extension, and it's about to be forcefully removed by Google. Someone has to save it. FoxDogStudios, make it happen.
not working, forgets that it was on
I used this extension RELIGIOUSLY. Is there any way you guys will be able to update this to fit Chrome's new policies?
You guys need to update because Google is trying to remove your extension.
I've been using this extension for years now, it's great. Updating the extension to work with modern Chrome is pretty easy, actually: - Download the source code, it can be found at the bottom of the page's description. - From the source code, open up manifest.json located in the src folder. - Change the "manifest-version" value from 2 to 3, and change "browser-action" to simply "action". Make sure to save manifest.json after changing these two things. - Go to chrome://extensions/ and load the unpacked extension from the src folder. Voila.
One of, if not the greatest chrome extension I have ever used. Its a shame that google took it away from all of us once and for all. I hope with all my heart some one does something about it. If it does ever get fixed and someone is reading this from the future. This was and if once again avalible is the cleanest, best quality pitch shifter on the internet. You can never go wrong with this extension.
Fix ur app pls
The extension worked perfectly, there was not a single time that it messed up, but it's being forcefully discontinued by Google due to "not following best practices". It's a shame, though. This was the best pitch-shift extension I've used.
Good
This app is so tried and true, and I've never seen a pitch shifting extension work as good as this one. The newer one's compression algorithm just doesn't work as well. This extension is so simple and clean. Please please open source the code so the community can keep this going if Chrome ever shuts this down for good.
rip to a real one
Great app but has been disabled by Google. I hope they update to Manifest v3 soon.
Super useful. Great extension.
Wish it worked on Firefox but I literally use this all the time. Very useful.
Entertaining. Can it please be programmed though to work for Rumble videos? It just mutes videos there.
This is the best extension that I've been using for years. I wonder why it doesn't work on tiktok? can someone help me this problem.
This is one of the best extensions I've ever used where I use this for YouTube videos and change the pitch and speed.
google seems to be targetting outdated extensions, so you may want to update this to manifest v3 so chrome wont end up automatically disabling it.
began to not work for some reason
I've been using this for years and it randomly stopped working lately, please fix this!!
The best pitch shifter!
For me the best pitch knob for vids as it offers smooth mode rather than just changing pitch in steps. Wish it had a larger pitch range. BEWARE this will stop working if you also use the "Video volume booster by NNT" extension :(
weird echo
I have been using this for years. I absolutely love it, very useful.
Very useful, this deserve more recognition, althought the quality of the pitch is not that good like a professional app but it does the job
Speed NOT STAYING IN PLACE!
Update this app asap. 3 years outdated? You guys can do better. Used to work wonders for me, but now it won't work on edge. It works on chrome, but now I can't use it with the sound booster extension I have (it'll let me use only one or the other). Fix this app
no workings for youtube!!!
Brilliant but wont work with some of audio extensions some conflict and turns back off like it wont work with this great extension https://mybrowseraddon.com/audio-equalizer.html

absolutely life-saving if you have misophonia. i know it wasn't created for this purpose but it does the job and it's so sensory friendly. 10/10.

Sorry! I installed this addon for exactly one reason. Pitch shifting, so i don't have to retune my guitar for every song i wanna play along with YouTube ... So called "Semitones" were totally off Details: I have my guitar tuned to Standard D 440. And with literally no setting on the Semitone range of the plugin, i was able to match it to the guitar. Back to capturing and reliably pitch shift songs in my DAW again, i guess ...

Can u add more speed like 4x or more?

Seems like the shift is inconsistent. -1 "semitone" sometimes needs to be a -2 setting, sometimes not, sometimes -3. Each song seems to be different. Otherwise it's great.
