Image from store Pitch shifter - HTML5 Video audio FX
Description from store # Now fixed!! # 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. --- Nerdy stuff: Uses Chris Wilso's Pitch Shift effect: https://github.com/cwilso/Audio-Input-Effects Tonal pitch shift is based off statical "line of best fit" from mmckegg: https://github.com/mmckegg/soundbank-pitch-shift Source code: https://github.com/foxdog-studios/pitch-shifter-chrome-extension

  • (2020-10-20) Steven Latimer: I want to play along to songs in Eb standard guitar tuning without retuning my guitar. Pitch shifting down sounds really good, but pitch shifting even a semitone up sounds distorted, unfortunately making this not the best solution.
  • (2020-10-17) TheRacoonBoy 712: it doesn't work on google photos fix this or else i will never use it for the rest of my life!
  • (2020-09-17) Adam Klar: Thank you! Finally I can listen to those YouTubers with annoying voice but good content.
  • (2020-09-13) jean-claude schwartz: Hello there. Your app is cool but this extension needs to be updated with PAL Pitch/Speed. Like for example 10.4 is PAL Pitched. It also needs more features as well.
  • (2020-09-09) Naaz Jiwa: The best, the most user-friendly. Just awesome++++
  • (2020-09-07) bobby decker: awsome and it still works in 2020 i can change the pitch and tune keep this forever and ever
  • (2020-09-02) thicc wicky 2: i mean even roblox sound shifter was better than this. it was decent, not too good but not too bad. nothing great
  • (2020-08-28) Koo Junhoe: I only discovered this to get high pitch too you just have to put the speed up from 1.0 to 1.06 it works from 1.02 1.03 1.04 and 1.05 and the same with low pitch from 1.0 to -95 so today i found out it doesnt do that anymore i dont know if its just mine but i kinda enjoyed having that but i cant seem to get it back does anyone have a solution :(
  • (2020-07-26) [Pae channel gamer]: It's work but.. it can go pitch at 1.6 it 1.7 i will only faster but not pitch please fix it and 1 tab above too!
  • (2020-04-11) gonzalo quiroga: never works it sucks
  • (2020-03-29) Peter Potthoff: Great tool for musicians trying to learn a new tune. Play alomg with a YT video, and use this extension to match your guitar's pitch, rather than re-tune ! It would be great if an option to change the scale of pitch change was included to allow a more precise match, but after using it a while, you can get a very close match. Kudos to the developer !
  • (2020-02-18) bananq: Works well when slightly slowing audio and pitch shifter is effective. Great app!
  • (2020-02-02) Nuttapong Punpipat: Pitch correction isn't good. Ex. In smooth pitch, set to 1 (should be 2x of original pitch) but as I hear when compared with other music instrumental, it's about 1.49830708x or 1.5x or vary sometimes Info: Tried on youtube video, and found more bugs about pitch adjusting.
  • (2020-01-13) Shaemus Slater: Works better than the pitch shift enhancement in Windows 10. Works even better when that option doesn't exist.
  • (2019-12-12) Putra Iqmal: after adding the extension, refresh the page first before using it. remember to switch it on lol. it works fine for me ;)
  • (2019-10-31) Sam GM: Works, but the drop in audio quality is way more than any other pitch shifter I've used in the past.
  • (2019-10-19) Law: Works like a charm! Have been looking for this as others extension seems not to be working. This is very important for musician like me. I use this to lower the key of Youtube karaoke video and then I could practice the song in my key! Thank you Pitch Shifter!
  • (2019-08-13) AU Lakeside Enterprises Fan Account: This is excellent when I got tired of hearing the original voice from most videos on YouTube, Dailymotion and others. The low and high pitch settings are perfect.
  • (2019-07-02) Codo UOC: Oh, God! This is so valuable for musicians! When you want to learn a song, but the singer has another type of voice than yours (i.e.: she is a woman and you're a man, or he is a man and sings too high or low for your kind of voice), you can set it to your tone and sing along! And for the difficult parts (voice ripples or fast solos), you slow the song down and you can hear every bit of music. Genius! Been using it for years now.
  • (2019-06-13) ondroth: this is dope thanks developers
  • (2019-04-05) Syarif Hamdi: The pitcher works, but quality definitely dropped when you lower the pitch or slow the song down.
  • (2019-03-18) Fahran Wallace: Not only does this work just perfectly, it is an honour to use a chrome extension written by the world's foremost rock & roll IT consultants. https://www.youtube.com/watch?v=8BpemSuaUtM&t=5m <---For those who've not met Foxdog Studios yet. You guys were my favourite show at the Fringe both years I went. I await your rise to rock and IT superstardom, for it is surely coming. In the meantime, thank you for the ability to make songs playable without breaking either my fingers or ears in the attempt.

  • (2020-09-14, v:1.5) Reetz.Buddah: Playback speed no longer changes pitch at all
    You used to be able to get a nice, high quality sounding higher pitch by setting your playback speed to between 1 and 1.05, now, the pitch stays the same whilst using playback speed slider. Also, using the pitch slider just makes the music distorted. Was there a change made?

  • (2020-09-01, v:1.5) jean-claude schwartz: Playback rate lacks Pitch
    Could you please fix the Playback Rate because i want it to have the same level as the pitch. When i put forward the speed, the Pitch will be with it like in PAL DVD
  • (2020-06-14, v:1.5) Jeremy Motts: step function
    Hi, cool extension, but I think it would be awesome if there was a step function to turn up and down the pitch change. This would be extra awesome if it corresponds to up and down by some standard increment like key or vocal range or something.

  • (2019-04-05, v:1.5) Amots Mor: not working
    hi, for some reason the pitch shifter not working for me. i use win 10 chrome, i do not do something special
  • (2018-10-22, v:1.5) chestofgreatness: Automatic Pitch Shift and Playback change
    When I finish watching or pause the for 24 minutes or an hour I play it again then the sound is different. I looked and the meter in Smooth mode it's still the same when I set but the sound and playback speed is still like that even in Semi-tone. Please Fix this.
  • (2018-10-12, v:1.5) Miranda Stein: Extension Won't Add
    Hi, I have downloaded the extension before and now for some reason it says it is downloading and it isn't. A popup keeps coming up saying reload or close because "it's downloading", but it isn't for some reason. Love the extension and want to have it.
  • (2018-05-31, v:1.5) doesn't work anymore !
    waz so fun !
  • (2018-05-19, v:1.5) Blanding Cassatt: Needs More Options
    Better than Realtek, which is Taiwanese, but has sound effects, equalization, and karaoke voice cancellation.
  • (2017-10-18, v:1.5) mattis n: let us disable Preserve Pitch
    Is it possible to make this change playback rate without preserving the original pitch? I want to fine-tune fine tunes like a DJ
  • (2017-10-13, v:1.5) Fidel Madrid: Not shifting by semitone
    I am pretty savvy at music and instantly recognized this issue. Essentially if you change the mode to shift the pitch by semi-tone the extension only shifts the sound a little less then half a semi-tone. A semi-tone otherwise known as a half step is for example G to G#. A full tone or a step is G to A. This is only different when you go a half step from either E or B on any octave, in both cases, a half step higher is F and C for each note respectively.
  • (2017-09-21, v:1.5) The More You Know: Doesn't' do anything
    Sounds the same to me I get no change in sound or speed ... nothing
  • (2017-09-03, v:1.5) 李立峰: Keyboard shortcuts?
    Keyboard shortcuts?
  • (2017-07-26, v:1.5) Dimitris Dimoulitsas: Pitch range
    it is a very great tool to sync your newly found track with the one turning on your technics MK2... But the pitch range based on 100% is a bit too extreeme and personally It doesn't overpass 0.80 and 1.20 My suggestion is to have some parameters to switch between -100%/ +100% AND -8% /+8% AND -16% /+16% (same than turntables) That would make the use of Pitch shifter much more precise and much more Pro ;)
  • (2017-07-20, v:1.5) 'ron 'shpatz cohen: pitch shift dosnt work
