Yes, it is free to use. If you like using the app your support is really appreciated!
You can use the extension on your desktop, laptop (Mac or Windows) or Chrome book.

The extension is compatible with other Chromium based browsers as well, such as Brave and Edge.
It can not run on Android or IOS.
This is how Chrome Edge visualizes that the audio of the tab is being captured. It says 'This tabs content is being shared' to inform you. When you open the extension and change the pitch the extension uses tab capture in order to process the audio contents of the tab.
The permissions are necessary to capture the audio for pitch shift processing and connect to the video players on the websites. This only happens when you launch the extension. No worries, we don't collect your data, browser history or audio and all your data is kept locally.
Transpose keeps track of a history list which is saved only locally, or at your Google Account and only accessible by you. We do use Google Analytics for usage and issue tracking. Check the privacy statement for more info.
  • Close or refresh any open tab windows with the (YouTube) video you want to control.
    This is sometimes needed first installation.
  • Not all media will work (only html5 videos). Some sites may block control of audio usage. Youtube and Vimeo should work!
  • There may be conflicting other extensions using audio tab capture as well. Check your extensions at chrome://extensions (type this in your browser address bar) and disable some. Close the video page first and see if it helps.
  • Uninstall the extension and reinstall it. Then close all tabs, exit Chrome, and try again.
  • Make sure you are up to date, check if you have the latest version of Chrome and this extension
  • If the audio cuts out when using this extension, check if this is also the case for other extensions using tab audio capture. If so, it may be a general issue of your device. This is an excellent guide to solve sound issues on windows 10:

  • If you can't get it to work, please contact us.
  • No media:
    There is no html5 video player found on the site. Navigate to a video, e.g. from Youtube first, and than launch the extension.
    If that doesn't work try the tips below:
  • No connection:
    The extension popup could not connect to the website:
    • It could be it is not allowed to connect to this page, like Chrome's home page tab
    • Close or refresh any open tab windows with the (YouTube) video you want to control.
      This is sometimes needed first installation.
    • Not all media will work (only html5 videos). Some sites may block control of audio usage. Youtube and Vimeo should work!
    • There may be conflicting other extensions using audio tab capture as well. Try to disable other extensions at chrome://extensions (type this in your browser address bar), restart the browser and retry.
    • Uninstall the extension and reinstall it. Then close all tabs, exit Chrome, and try again.
  • Could not capture audio:
    There may be conflicting other extensions using audio tab capture as well. Try to disable other extensions at chrome://extensions (type this in your browser address bar), restart the browser and retry.
  • Page does not allow extension:
    On some pages, it is not allowed to connect to the content.
  • Pitch shift only mode:
    If there is no HTML5 videoplayer in the content the functionality is limited to transpose and pitch. It is not possible to change the speed, use the loop feature. The settings will not be added to the history list.
    But, you can pitch all audio in the browser tab. As an example, you can use it for the Spotify web player: https://open.spotify.com
  • Make sure you are up to date, check if you have the latest version of Chrome (70.x and up) and this extension
Yes, you can use transpose and pitch, but there are limitations:
  • You cannot use it for the Spotify application, but for the equivalent online version which runs in the browser: https://open.spotify.com.
  • It is not possible to control the speed, loop and transport controls.
  • Settings will not be added to the history list.
Yes: go to the settings page by clicking on the '3 dots menu icon' in the top right of the extension and click 'Play File'. This opens the local file player, you can browse for an audio file on your device and use the extension to control it.
You can use it for all kinds of audio formats, such as mp3 or wav but it also works with mp4 video files (audio only).
No, that is not possible. It is not allowed by Terms of Service for most sites, like YouTube to use an extension for that. But of course there is external software that can do the trick. Check out Audacity, an open source audio editing solution for Windows and Mac.
Yes that's possible, but only if you cast the desktop. See https://support.google.com/chromecast/answer/3228332
Unfortunately audio processing is not highly optimized for browser extensions and performance depends on your device.
If you do encounter glitches, try to close other tabs and applications, and disable other extensions.

Please keep in mind this is an aid for practicing, not a studio tool :)
That is normal when using the high quality pitch algorithm: the audio is buffered for processing (200 to 400 milliseconds). You can set it temporarily back to low quality in the settings you need it in sync.
When you activate the extension, tab capture is activated for that browser tab. As a security measurement by the browser, the title bar is still visibile in full screen mode.
There are several workarounds:
  • Open a new tab
  • Stop audiocapture (button in the settings of the extension)
  • Manually set the browser in Full Screen (F11, or browser zoom settings)
Currently all features are free to use! If you like using the app your support is really appreciated!
