- (2025-05-04) ruub: This is the best plugin ever. I've used this for so many years now. However, it's a big shame it's not up for download anymore. I tried to get it on my other devices too but I guess it's not being updated accordingly... PLEASE DO
- (2025-04-30) Nikola Negovanovic: Absolutely Irreplaceable! You can listen your songs to literally any frequency with just a few clicks. As someone with perfect pitch, this extension means everything to me. Changing the key of a song is like looking at the same painting but with different colors. It keeps the songs alive. I literally use it all the time. My passion for music couldn't live without it. There is no extension for chrome I know that does the job better than this one. The app is great too but it takes time, with the extension you can do everything instantly. It is true that on some devices, the quality of sound may diminish when the extension is turned on. But there is an easy fix for this! Either keep your device plugged in the whole time or connect your device to an external speaker. Edit: I'm disappointed to see that this extension is no longer supported on Google Chrome. At this point in time (April 2025) it is still available on Microsoft Edge.
- (2025-03-23) Шабски: I love how you can change the pitch as the song plays. It gets a bit choppy once you mess with the speed though. It's a shame that google chrome doesn't like it
- (2024-09-06) Akron 1992 (Akron1992): my it works only i can watch everything on YouTube and much more videos that iUsed for my Transpose so iCan update and take my Extension web store.
- (2024-08-25) Codey Rivera: please makesure you update this extension to manifest version 3 please but can you make the pitch option up to 72 semitones please instead of 12 semitones
- (2024-08-04) vidal sanchez: Not runs on spotify at all. Seems there is no way to increase tempo on spotify, always shows 100% full tempo with no way to increase tempo.
- (2024-07-30) Davide Fe: It works, but it doesn't help to tune audio to Solfeggio frequencies like 432hz. The pitch slider don't change only the frequency, it changes the tone also making the music awful to listen. Plus, you cannot tune the frequency you want, because the slider doesn't translate visually the level you choose into the frequency.
- (2024-03-25) SpilledKetchup: Pales in comparison to its vastly more powerful app, when changing pitch, the quality diminished heavily unlike the mobile app.
- (2024-03-19) Metis: works on youtube music!!! this was the only extension i found for youtube music i am grateful!
- (2024-03-16) Raef Black: you need to adust the rewind , so that you can gp backwards to the intended point
- (2024-02-23) Beppe Bassani: Awesome! I am using it daily for music practice etc. Suggestion: what about having more than 100% tempo? This way it could also be used to speed up music and videos.
- (2024-02-20) Phillip Greg Haygood Jr (PJ): good to me.

- (2023-04-15) Павел Науменков: Меня очень сильно расстроило, что нельзя увеличить скорость при прослушивании музыки. Исправьте это и дайте возможность слушать музыку не только в нормальном и замедленном, но и в ускоренном режиме.

- (2023-02-21) Jamari Broussard: The one thing this extension does better than the others is when you change the tempo it doesn't sound choppy, and the transposing works perfectly as well. theres also a mobile app as well that allows you import your music library, I recommend it.

- (2022-08-01) Carrington Woods: This extension is okay. Just okay. Why? Two reasons: 1: when you enable the extension in any tab, a box appears in the tab. Hovering over said box shows a message reading, "This tab's information is being shared." Shared where? This also prohibits the tab from full screening correctly (if you are using for YouTube). 2: Sound quality is diminished when you change the pitch in any direction. Sounds choppy and "far away." Other than those two reasons, this is an okay extension unless you can find something better. I am looking for something better now. Sorry, not sorry.

- (2022-06-24) Courtney Mansell: Great for the price of $0! ;) But when I use it on my Spotify web player, the pause/play buttons then have really unpredictable delays. Sometimes I have to click back into the chrome extension pop up to get the pause/play I have pressed to catch up or start to work. It's a bit tedious and clunky, but eventually gets the job done, didn't cost me anything, and is better than the alternative - which is nothing!

- (2022-05-18) Silvan Armbruster: Works as it should, so its a really nice Chrome extension. Only thing I think is really not well thought through is, that the speed changer is limited to 100%. I mainly downloaded it to speed up some tracks, so its kinda useless for me.

- (2022-02-23) Dani ENT: I've been using this app on my phone from the Google Play store, and now I am so happy that this app is now available on the Chrome web store for my Laptop computer as a Google Chrome web browser extension. I am so happy that this app is here...especially because I now have an iPhone--Apple---and I can not find this app on the App store. All this extension needs now is the Equalizer tool, then the MusicSpeedChanger extension will get 5 out of 5 stars. I am very very grateful that MusicSpeedChanger is now an extension for Google Chrome!!! Thank you, developer(s) so much for this!!!

- (2021-10-03) J Eng: This is a huge help since Spotify kicked off 3rd party apps like Djay! Would be great to have an option to lock pitch to whatever's appropriate for the chosen tempo, like the single speed slider on a turntable. (I know that only works for shifting down in some cases like Spotify, but I would still find it useful!)

- (2021-06-22) Katrina Bernal: This is quite exactly what I'm looking for. An extension that pitches at the fine tune level (semitone). Sometimes when you start it up it sounds a bit choppy. And for some reason, the pitch will change into something completely different as you listen to a song. I only pitched as far down at -27 in the Tune section, but I can definitely hear it changing key here and there, getting very low in sound. I think the extension has a lot of potential, so I hope these things can be fixed, eventually. Thanks for putting this out.
