• (2024-02-08) Dr Barry Raphael: For when the music is better than I am...which is almost always...it helps me tackle and conquer at my own pace. Suggestion: I would like to be able to save settings to have a bank of tunes.
• (2024-02-04) Sharon Gilchrist: Love it! Easy, works & can finally work with video footage. Many thanks.
• (2024-01-30) Daniele Midi: Absolutely perfect for anyone who wants to use YouTube to practice music or singing!
• (2024-01-09) Dave Leech: Very useful, simple and has the features I need.
• (2023-12-29) Nexsus: Are you able to reupload the old version of the extension? Why not make it a separate extension have the Classic back and have this version separate so you the devs can do what you want with this version. Yea it did get an update it still feels like the old one is still better due to this one have problems like no exit button, cracks and pop still there, feels like the smoothing got messed up and also the smoothing button is gone to.
• (2023-12-24) Eli Mason34: It was great for transposing videos, but now it stopped working all of a sudden.. Please fix it!
• (2023-11-12) Marcelo Mammana: Brilliant! Easy to use, very accurate! Thanks!
• (2023-11-06) Tony Beninate: Super-useful and reliable; thanks!
• (2023-11-05) Vikram: Top class utitility for singers. I would find it extremely tedious to sing on many singer's original pitches. Here I can get the song within my range - practice it and sing it. Delightful app! I only wish the author also does an android or ios version.
• (2023-10-29) TheLuckyDonut: Everything I wanted and more! I've always wanted something that could pitch shift youtube videos on the fly, and now I can!
• (2023-10-28) Stephen Tate: Love it, so useful!
• (2023-10-28) GC 117: This is really cool its like a replacement for the Realtek Audio App if it was a desktop app this would be really fantastic so I can change the pitch and others in iTunes and other stuff
• (2023-10-23) Kris V: This extension is great for singers! Learning a new classical art song the slow down capability helps tremendously. The key modification is also great in helping to find the right key for the singer and "modify" accompaniment to the needed key. It all works great as the extension preserves the sound quality of the original video. It is simply AWESOME! :)
• (2023-10-23) 安藤幼君: 以捐款支持
• (2023-10-22) ArcMove: Превосходное расширение для гитариста.
• (2023-10-22) Simon Jurecic: Great tool, really helpful and works like magic!
• (2023-10-22) Eduardo Nouel: Funciona muy bien.
• (2023-10-19) Trevor Hart: Why didn't YouTube even think this in the first place? This extension, alongside the Android app NewPipe, allow you to mess with the pitch and speed. I like to put the speed at 1.04x, as a way to mimic a NTSC-to-PAL transfer of said content. Yeah, I'm a geek.
• (2023-10-18) Simon A: Does exactly what it's supposed to and works great.
• (2023-09-27) awxii: I've always loved using this extension over the years, but I think there's a bit of a small bug that needs to be fixed. If you try to slow down a YouTube video after enabling this, it doesn't work and glitches out? You can still slow down videos with the actual extension itself, but not slow a video down with the actual YouTube settings, because it's overwritten by the extension's speed when trying to do so. The extension's speed is supposed to adjust automatically and sync to the YouTube video speed, but it stopped working? It's a little inconvenience for me personally but I'd love if you could plz somehow fix this thx.
• (2023-09-23) Faraday Fung: hope the extension can be available on Firefox too!
• (2023-09-21) Digant Shah: This is exactly what I was looking for. And it works perfect. Thank you developers for this extension. Bought the membership of your site. Keep this alive.
• (2023-09-20) ardyarde: I use the transpose effect to pitch down songs I always liked and it's like hearing it for the first time. Works great with vocal chorus.
• (2023-09-17) Arhan Ghosh: Mad useful tool for musicians. I'd kill to have something like this on android. There is no technology like this
• (2023-09-16) Johann Hough: Awesome!
• (2023-09-16) Cara, não costumo voltar pra deixar reviews com frequência. Mas essa extensão realmente me surpreendeu.
• (2023-09-15) Mari Laleczka: I cannot live without transpose. I'm being serious when I say this I am able to speed up unskippable ads Adjust the pitch of songs to change my listening experience Life saver asf Also remembers how you adjusted the extension with each specific video (if you used the extension with them) Thank you transpose
• (2023-09-14) Lene Dalen: Amazing program! A true game changer for a music student. Thank you so much!
• (2023-09-12) Leonardo: Incrivel! Amei a Qualidade, Porém como nada é perfeito, Tens de muito mudar, Ao Longo da Musica, Ouço o Tom Aumentando e Diminuindo Sozinho, O Problema Ainda Persiste e Tem que Ser Trabalhado
• (2023-09-01) Jarrod Williams: I'm old. This extension is nothing short of magic. Where was this 30 years ago? Thanks for your work!

• (2023-07-23) Tim Last: So useful - love it for practicing / learning songs in different keys.
• (2023-07-22) FIM-43 Redeye: I love this extension, but it HAS TO SWITCH OFF CHROMIUM. https://www.youtube.com/watch?v=0i0Ho-x7s_U Google is killing the open internet. Please, I beg you, move to Firefox. I've been staying on Chromium for ages because I love this extension that much, but this is dangerous.
• (2023-07-22) Hugo: I would love a keyboard shortcut to jump to the next/previous marker. I use it to practice guitar with and I could bind the shortcut to a MIDI controller to easily jump through a song
• (2023-07-18) Wes Gibbs: Love this app! It's the app I wish I had when I was 15 constantly rewinding a section of a song in my cassette deck so I could learn it on guitar! It's made the process of learning new songs so much easier.
• (2023-07-14) Olivier Deslandes: Just perfect :-)
• (2023-07-10) Matt Lee: Very practical tool for music learning. It will be even perfecto if the audio lag can be further minimised
• (2023-07-06) Greg Zangari: If it had the ability to transpose through an entire playlist of songs on YouTube without needing to reset the app to transpose for each song, it would be a more effective tool. Is that a possibility? That's what it would take for me to change my rating to 5 stars.
• (2023-07-05) miku: no longer works
• (2023-07-04) Taylor Ellsworth: Works so well! This app finally let me enjoy my favorite song again!!!
• (2023-07-04) Olof Bergström: Excellent tool! Can´t do without it for learning new songs and instruction videos. Highly recommended!

• (2018-08-06, v:2.0.19) Jason Silver: Extension is Missing
  I have the paid version - today it's missing, even if I disable and reenable it, it won't appear in toolbar.
• (2018-07-07, v:2.0.17) Phương Nguyễn: Have noise when transpose.
  Hi, i has bought Pro Ver, and turn on High Quality, but when i use it, it have some small noise. How can i solve it? I don't use other extensions using audio.
• (2018-06-29, v:2.0.17) Eeshton: Can't buy pro
  When I try to buy pro, it opens a window that has a little Chrome icon loading animation, it finishes, and thens there just an infinite white screen. I have made sure my payment options are correct for my google account.
• (2018-06-28, v:2.0.17) KitoMero: Lost Pro Version
  I reinstalled Chrome from scratch but the Pro version that I already paid for is gone? How do I get it back? And how do I get this Pro extension on my laptop as well as my PC? Why doesn't it upgrade me to Pro automatically?
• (2018-06-08, v:2.0.17) Cameron Paulin-Smith: Transpose - Pitch - Loop for videos
  Yes, for perfect loops that is necessary. Unfortunately it is not possible to control html5 players such as Youtube with such a precision; this is also not the aim of this extension, I would recommend a tool like Audacity to do this!
• (2018-06-08, v:2.0.17) 432Hz
  I've been wanting to listen to music tuned to 432 Hz vs 440. What is the most accurate setting to do this?
• (2018-05-15, v:2.0.16) Swateja Adawadkar: Changing the pitch of Audio
  Hi, I am fairly technologically challenged and I am not sure if this extension will work for audios as well. I want to change pitch of a few MP3 songs that are in my PC. Is it possible to do that or the extension only works for videos?
