PitchShed
Pro
Change the key
Move a song up or down by as many as 12 semitones — a full octave either way. Fit the song to your voice, or to the guitar in your hands. It plays live in the tab; nothing is downloaded or recorded.
A practice tool for your browser
Change the key. Slow it down. Loop the hard part.
PitchShed lowers or raises the song you are practicing in semitones, slows it down without changing the pitch, and loops one section — right in the tab where it plays. It remembers your settings for every song, so tomorrow's practice starts where today's ended.
Speed is free for good. Everything else is free for 7 days — no card, no sign-up. See the pricing.
The store listings open soon. These buttons switch on the moment they are live.
How it works
-
Add it
Install PitchShed from your browser's store. It asks for no access to the sites you visit — it can only touch a tab after you click its icon.
-
Play something, click the icon
Start any video or audio on a page — a YouTube video, a backing track, a lesson — and click the PitchShed icon in that tab.
-
Set it and play
Move the key in semitones, set the speed, mark A and B to loop a section. PitchShed saves it for that song, ready for next time.
What it does
Free
Slow down, pitch stays put
Slow a passage to 50 % or speed it up to 150 %, in 5 % steps. The pitch does not move, so it still sounds like the song. Free, with no time limit.
Pro
Loop the hard part
Press Set A where the hard part starts and Set B where it ends. PitchShed repeats the section until you stop it, and you can nudge either point by a tenth of a second.
Pro
It remembers every song
Key, speed and loop points are saved for each song on your device — up to 500 songs. Open the song next week, click the icon, and it is all back.
Free to start. Pro when you need it.
Speed control is free for good. Every installation also gets all of Pro free for 7 days — no card, no sign-up.

Where it does not work — said up front
- Services that protect their audio (DRM), such as Spotify and Netflix. PitchShed cannot reach that sound, and it does not try to.
- Sound that comes from another website without permission. If a page plays audio from a different domain that does not allow it, PitchShed switches the key control off instead of silencing the sound.
- Videos inside embedded players on other pages. Version 1 works on the page you click in, not on players embedded in it.
- Phones and tablets. PitchShed is an extension for desktop Chrome and Edge.
- The original singer's voice. PitchShed shifts the whole recording. It does not remove or separate vocals.
Questions
What is free, and what is Pro?
Speed control (50–150 %, pitch kept) is free with no time limit. Key change, A–B loop and song memory are free for 7 days after you install, and after that they need Pro: $4.99 / month or $29.99 / year. The trial needs no card.
Do I need an account?
No. There is no sign-up and no login. Pro is unlocked with a license key that you paste into the extension, or that the page you buy on hands to it for you. One key works on up to three browsers or machines.
Does it work with Spotify or Netflix?
No. Those services protect their audio with DRM, and PitchShed cannot process it. It works with ordinary web video and audio, for example on YouTube.
Does it download or record anything?
No. The sound is changed live inside your browser tab and goes straight to your speakers. Nothing is saved, uploaded or shared, and there is no download button.
Do I have to click the icon every time?
Once per tab. PitchShed only ever touches a tab you click it in, which is why it needs no access to the sites you visit. After the click it stays on in that tab, also when you move on to the next video on the same page. A new tab needs a new click, and the settings you saved for the song come back with it.
Is the sound delayed?
Changing the key adds a small delay of about a tenth of a second (0.12 s) to the sound, so the sound trails the picture slightly. With the key at 0 nothing is added, and a plain audio track has no picture to be out of step with.
Which browsers does it work in?
Desktop Google Chrome 116 or newer, and Microsoft Edge. Both stores have the same extension.
What does PitchShed send over the internet?
Your audio never leaves the browser, and there is no analytics. The only traffic is a license check with our own license server: when you activate a key, and after that at most once every 7 days. The privacy page has the details.
How do I cancel?
Use the link in your Paddle receipt email. Canceling stops future payments, and a refund within 30 days is yours for the asking — see refunds. If you would rather not deal with it yourself, email support from the address you paid with.
It does not work on a site I use.
Tell us which one: email support with the page address. Some players can be supported; others, such as DRM-protected services and audio served from another domain without permission, cannot.
