The Audio Studio, Practice mode, the YouTube extension and one-click tools work together and share the same features — all in your browser, with nothing to install.
Each one has its own job. Together they cover the whole workflow, from the first listen on YouTube to the finished track.
The online studio for your own songs and videos. Change everything, preview for free, then export.
One screen to rehearse on: the video or the lyrics in front of you, every setting on the right.
Change the key, pitch and speed of any YouTube or YouTube Music video in real time — and with Studio mode, keep every control in a side panel right next to the video. Free, with no account.
Need one thing, fast? Each tool does it in a click, then hands your file over to the studio to keep going.
See all the toolsSwitch on Practice mode in the player and the studio rearranges itself around what you are working on. Everything fits on one screen, with nothing to scroll. And the navigation bar steps aside, for a cleaner, calmer screen.
Keyboard shortcuts: Space to play or pause, A and B to set the points, L to switch the loop on or off.
The same building blocks run through the whole ecosystem. Here is what each one does, and where to find it.
Change the key by semitones, from −12 to +12, without touching the speed.
Fine-tune the pitch in Hz, from 415.3 to 466.2 Hz — 432 Hz included.
Slow a song down or speed it up without changing its pitch.
Repeat a passage between point A and point B, again and again or just once. Save it in My recordings in the Audio Studio, or in the extension's library.
The key, relative key, Camelot code, tempo and half/double-time of every file.
Split a song into the isolated vocal and the instrumental.
Reverb and 8D audio — plus one-tap styles such as Slowed + Reverb in the Audio Studio.
Back to start, 5 seconds back or forward, and a bar you can click anywhere.
Paste the words next to the controls and size them for your eyes — kept for each song.
Send a track with its exact settings, valid for 7 days — opening one is free.
Save songs with their settings and sort them into folders. A/B loops can be saved too — in My recordings as in the extension — to reopen just one passage.
Download the result as MP3, WAV or MP4, to use it offline.
KeyPitch in Chrome's side panel, right next to the video, which switches to theater mode on its own.
10 bands, from 32 Hz to 16 kHz, and 6 presets: Bass, Vocals, Treble, Warm, Bright and Loudness.
Current and longest streak, practice time, songs practised and active days, in My space.
Rearrange the cards in the order you like; the layout is remembered.
Four tools that work together: the Audio Studio, an online studio for your own audio and video files; Practice mode, its one-screen layout for rehearsing on a computer; the free YouTube extension, which changes the key, pitch and speed of YouTube and YouTube Music videos live; and one-click tools such as the Key Finder and the BPM Finder. They share the same features: transposer, pitch changer, speed control, A/B loop, track analysis, AI vocal remover and effects. {userCount} people use them.
Track analysis and the player are free for everyone, with no account needed. Practice mode and its A/B loop are free for 5 minutes a day, and unlimited with a subscription; on YouTube, the extension's A/B loop is free. Otherwise, you only pay if you want to download your edited file.
Because its purpose is to show everything at once: the video or the lyrics on the left, every control and the A/B loop on the right. A phone screen has no room for two columns. The switch appears in the player on screens at least 1024 pixels wide, used with a mouse or a trackpad.
In Practice mode, set point A and point B at the playhead with the buttons or the A and B keys, or drag them along the bar. Infinite jumps back to A every time B is reached. Single plays the passage once, returns to A and waits there, paused, so you can sing or play it back. Save the loop in My recordings and you come back to exactly that passage, with its settings.
The analysis runs in your browser as soon as the file is loaded: it compares the notes played across the whole track with the 24 major and minor keys, and measures the beat. Click the ⓘ button under the player to see the key, the relative key, the Camelot code, the second most likely key, the tempo, the precise tempo and the half-time and double-time readings.
The extension, to work live on a YouTube video, for free. The Audio Studio, for your own files, when you want to export, separate the vocals, share or save a track. Practice mode, inside the studio on a computer, to rehearse with the video or the lyrics in front of you and an A/B loop. A one-click tool, when you need a single thing fast: the key, the BPM, a slowed + reverb version.
A new way to use the free extension: KeyPitch opens in Chrome's side panel, right next to the video, and YouTube switches to theater mode. It has three tabs — Controls, with a 10-band equalizer and the redesigned A/B loop; Library, which now saves loops as well as songs; and My space, which tracks your streaks and practice time. Not to be confused with the Audio Studio, which works on your own files.
Load a file: its key, its tempo and Practice mode are waiting for you.
