Yes. Transpose lets you change pitch and speed and use loops for as many songs as you like, without an account.
You can also use the complete Studio toolkit on three songs at a time, without an account or expiry date. A subscription or Lifetime gives you Studio for unlimited songs.

No. Transpose is made for practice during playback and does not export adjusted audio, recordings or separated stems. Save stores your practice settings, not the music itself.

Transpose has no dedicated Chromecast integration. Casting can only work when you share the entire desktop or browser tab together with its processed sound. The result depends on the browser, casting method and receiving device.

Transpose needs permission to find and control the player on a page. An embedded video can require permission for both the page and the player website.
Choose Allow access and confirm the browser prompt. You can revoke access later under Settings → Data and reset → Revoke permissions.

Try these steps in order:
See the Tab Audio controls.
troubleshooting no media connection no sound
Open Spotify at open.spotify.com and check where it is playing. If a phone, speaker or another computer is selected, the sound is not coming from the browser tab and Transpose cannot process it.
Select This web browser in Spotify, use one playing Spotify tab, start the song and reopen Transpose. Allow access if asked. If a direct connection does not work, try Tab Audio.

Transpose cannot find a usable player on the current page. Open a page with audio or video, start playback and reopen Transpose. Prefer the media's own player page over an embedded preview.
If the website uses a non-standard or protected player, try Tab Audio.

Choose Allow access if the website needs new permission and confirm the browser prompt.
Already allowed access but asked to activate from the toolbar? Click the Transpose icon in the browser toolbar to reconnect the current tab. Close and reopen Compact or Side, then refresh the page if that does not help.
activation required allow access reconnect
Transpose found a player, but the music is not playing yet or the connection became stale after the page changed. Start playback on the website. Reopen Transpose or refresh the page if needed.
start playback connection player
Transpose can hear audio but cannot attach pitch processing directly to the player. Choose Tab Audio, confirm the browser prompt and use the website's playback controls when needed.
Other audio, video or recording extensions can interfere. Temporarily disable them if Tab Audio does not start.
pitch not available no compatible player Tab Audio
Use Tab Audio when Transpose cannot process a website's audio directly. Tab Audio uses all sound from the current browser tab.
You can adjust pitch and sound, but playback and seeking may need to be controlled on the website. Stem Mix is unavailable in Tab Audio. Stop the mode from the capture card or Settings → Tab Audio.
See the complete Tab Audio controls.
Tab Audio tab sound fallback
Close heavy tabs and applications, temporarily disable other audio extensions and refresh the music page. Switch extra effects off one at a time to find which combination causes the problem. Restart your browser if it continues.
Check the sample rate of the device you use to listen. If it is set to 96,000 or 192,000 Hz, change it to 48,000 Hz (48 kHz), then reload the music page.
Studio Side
Temporarily turn off Stem Mix, or disable Music analysis (chords, key, tempo and beats) in Settings. This helps you check whether stem processing or analysis is putting too much load on your device.
With Stem Mix, an unprepared section can temporarily play as the original mix. Let that section play so Transpose can process it.
audio quality stutter distortion performance
Audio effects need processing time. Noticeable delay depends on the website, your device, the selected effects and how Transpose connects to the player.
If the audio also stutters, check your output device’s sample rate.
Studio
For an active Studio song, try Settings → Audio → Low Latency. This prioritizes a quicker response over some sound quality. Low Latency is unavailable while Formant has been adjusted.

Stem Mix needs an active Studio song, a direct audio connection and a device with WebGPU. The required tools are installed when you use Stem Mix. Stem Mix is disabled in Tab Audio. Varispeed also switches Stem Mix off. Turn Varispeed off, then enable Stem Mix again. Prepared stems and mix choices are retained.
If Stem Mix is active but you temporarily hear the original mix, the current section may still be processing. See Stem Mix.
See how to enable WebGPU in Chrome.
Stem Mix WebGPU unavailable Tab Audio
Stem Mix does not always separate parts completely. With Solo, you may still hear traces of other instruments; with Mute, the muted vocals or instrument may remain faintly audible. This depends on the recording and how the parts overlap.
The model is chosen to balance audio quality, processing speed and the load on your device. This lets Transpose process music during playback, but the separation is not always completely clean.
Stem Mix stems split Solo Mute vocals separation bleed leakage
The waveform can be built without extra analysis tools. Chords, key, beats and tempo estimates require you to install music analysis first. They also require WebGPU.
Play the song so Transpose can process the music. Results appear progressively and can vary by recording. See Install music analysis.

Check Settings → Remember changes. With Do not save, new songs are not added to Recent.
Recent belongs to one device and browser profile. Guest or private mode, clearing browser data, a cleanup tool or reinstalling the extension can remove local history. Find account-saved songs under Library → Saved after signing in.
Recent history missing browser data
If the song was only in Recent, its settings were stored locally. That history does not transfer to another computer and can disappear when browser data is cleared or the extension is reinstalled.
Replacing a Studio song does not delete its saved version. See Save and Library.
saved settings missing lost restore account version
A saved practice version does not automatically give that song access to Studio tools. Open the song in Studio and, if needed, choose which of your three songs to replace. Unlimited Studio does not require replacing a song.
Your saved version is retained. See Replace a Studio song.
