Our Mission: Encouraging Music Making

We believe that making music is for everyone. That's why the core of Transpose is a powerful, free tool for your daily practice sessions. It is our contribution to the music community, to help as many people as possible grow and enjoy playing.

The Classic version contains all the features from the original extension, which we've been improving since 2017.

• Works on YouTube, Spotify, SoundCloud, Deezer, and many more.
• Includes pitch, speed, and loop control.
• Keeps track of your recent history song settings

Transpose Pro is a new, optional upgrade.
It adds an improved pitch algorithm, plus extra features like formant control, vocal reducer, advanced loops, clips, and presets.

Upgrading is not required. Classic users keep the same free experience they always had.

If you see 'No media' or 'Connection error', or there is no sound:

• Refresh the page.
• Start playback before opening the extension.
• Ensure latest Chrome/Edge.
• Open the video on its dedicated page (not embedded).
• Close other tabs or restart browser.
• Disable other extensions that may use audio capture.
• Reinstall the extension if problems persist.

Note that some sites do not allow connection to their media. As a fallback you can use Tab capture mode.

Free and Pro versions both depend on device performance.
Tips:

• Close other tabs and applications.
• Disable unnecessary extensions.
• Check your task manager for background processes (e.g. updates, backups, virus scans) that may affect audio performance.
• Restart browser or computer.
• Check sound card sample rate (48kHz recommended).

Pro users:

• Pro uses an improved algorithm that reduces clicks and noise.
• Delay is much lower compared to the Free version.
• On weak PCs, glitches can still occur.

troubleshooting audio quality glitches jitter stuttering distortion performance noise

Pitch shifting requires buffering the audio (200–400ms).
This delay between audio and video is normal in the Free version.

The Pro version uses a different audio engine, and has by default a much better latency.

Yes.
Transpose Pro uses a more advanced algorithm with:

• Minimal audio delay (much closer sync with video).
• Fewer clicks and artifacts.
• More natural sound, especially at extreme pitch or speed changes.

• Vocal Reducer — lower centered vocals in stereo mixes
• Advanced looping with:
  • High-resolution timeline and draggable markers
  • Wait-in counts, laps, and more accurate playback
  • Scrubbing preview when paused
• Clips & sequences
  • Save fragments with their own pitch, speed, formant, and vocal reducer settings
  • Chain clips into practice sequences (e.g. slow → medium → original tempo)
• Efficient looping station — rehearse with multiple markers and loop ranges
• Save your work in the cloud
  • Clips, sequences, and presets sync across devices when you sign in

In Transpose Pro, loops are much more precise and flexible than in the Free version.
They use a higher-accuracy algorithm and frame-based timing for smooth, gapless playback.

Creating an advanced loop

• Click the Range button.
• If there are only two markers, they are auto-selected as the loop range and the repeat icon is enabled.
• If there are more markers, all marker buttons and timeline heads (①, ②, ③ …) start blinking:
  • Click once to choose the start marker.
  • Click again to choose the end marker.

Long press a marker button to get in to range select mode directly

Loop playback options

• Repeat icon → toggle the current loop on/off.
• Laps icon → repeat the entire song.
• Wait-in count → insert 1–4 metrical counts before each repeat, based on the tempo setting.

Marker interactions

• Click a marker → jump playback to that time.
• Long-press a marker → enter select range mode.
• Markers button or Shift + click → enter edit markers mode, where you can:
  • Rename the label.
  • Adjust the exact time (input).
  • Sync the marker to the current playback position (location icon).

Timeline

• Markers are shown as rounded numbered circles (①, ②, ③ …) in chronological order.
• Click a circle to jump to that time.
• Click anywhere on the timeline bar to jump; when paused you get a short (≈300 ms) preview (scrub time configurable in Settings).
• Markers are always sorted by time.
• Click the + button at the end of the marker list to create a new marker at the current time.

Tip: Combine advanced loops with clips (see What are clips and how do I use them?) to build step-by-step practice sequences.

pro features looping loops markers clips timeline

The Free version has a simpler loop system with basic markers.

Adding markers

• Click the bookmark icon to save the current time as a marker.
• Each marker shows its time and optional label.

Using markers

• Click the → jump icon to move playback to that marker.
• If two markers follow each other in time, you can loop that segment by clicking the repeat icon between them.

Loop toolbar options

• Repeat song → loop the entire track.
• Wait-in count → add a short count-in before repeating.
• Sort → reorder markers chronologically.
• Add → create a new marker at the current time.

Free loops are handy for quick practice ranges, but they lack the higher precision, editing, and sequencing options of Pro advanced loops.

Transpose intentionally keeps pitch and speed independent.

• Musicians need to slow down fast passages without changing key, or change key without changing tempo.
• Linking them (varispeed, like a tape deck) would make practice harder, not easier.
• Independent control is the core purpose of Transpose.

varispeed pitch speed features linked

In Transpose Pro, practice fragments are stored as clips.
A clip is a saved audio range (loop) with its own playback and effect settings.
Unlike simple presets, clips are tied to a time range in the track.

Creating a clip

1. Select a range by setting start and end markers.
2. Click the scissors ✂️ icon to cut and save the range as a clip.

Editing a clip

• Click start time, end time, or name to edit them directly.
• Use the + menu inside the clip to add or adjust parameters such as speed, transpose, formant, or vocal reducer depth.
• Each clip remembers its own parameter values.

Playing clips

• Press Play on a clip to start playback from that point; the rest of the sequence continues after it.
• Clips repeat automatically according to their loop setting.
• You can insert wait counts between clips to pause before the next one starts.

Managing clips

• Duplicate a clip quickly from the ⋮ More menu.
• Rename or reorder clips to build your own practice flow.
• Chain clips together to form a sequence (e.g. the same fragment at different speeds or pitches).

Clips let you practice step by step, gradually increasing speed or changing pitch, without having to reset settings manually.

Formant control changes the timbre (voice color) without affecting pitch.

• Useful for adapting male ↔ female voice range.
• Can make instruments sound darker or brighter.

The Vocal Reducer uses Mid-Side processing to isolate and reduce the center channel of a stereo track, where vocals are typically placed.

It is not perfect on every song, but it can lower vocals in many cases. Results depend on how the track is mixed.

Main controls:

• Vocal reducer (Depth)
  Master dry/wet control.

  • At 0% the original signal passes through.
  • At 100% you only hear the fully processed signal.
  • Default 80% = strong but blended effect.

• Vocal Cut (vocalCut)
  Crossfades between two reduction techniques:

  • 0% → multi-band notch filters (precise, cleaner).
  • 100% → phase cancellation (L–R subtraction, more aggressive, may add artifacts).

• Center Focus (centerFocus)
  Shifts the stereo focus of the reduction.

  • Useful if vocals are not perfectly centered.
  • Move slightly left or right to better target vocals before Mid-Side processing.

• Precision (Q)
  Controls the filter sharpness:

  • High Q = very narrow, surgical cuts.
  • Low Q = broader cuts, better for variable vocals but may affect nearby instruments.

• Low Cut / High Cut
  Pre-filters to clean the signal before reduction:

  • Low Cut: removes rumble below e.g. 100 Hz.
  • High Cut: removes hiss/“air” above e.g. 8000 Hz, helps reduce artifacts from cymbals/hi-hats.

Tips:

• Start with - Vocal reducer (Depth) first, then fine-tune the other controls.
• Works best on stereo mixes where vocals are centered.
• May not fully remove vocals; it is designed for practice and karaoke use, not for studio-quality separation.

The old one-time-payment Pro was made free for everyone in 2021.
That version is now Transpose Classic (Free).

We believe that making music is for everyone. That's why the core of Transpose is a powerful, free tool for your daily practice sessions. It is our contribution to the music community, to help as many people as possible grow and enjoy playing.

The Classic version contains all the features from the original extension. The new Transpose Pro is an upgraded edition with more advanced features and separate licensing.

If you once bought the old Pro, you now effectively have the same version with Classic. Upgrading is not required. With Classic you keep the same experience you've always had.
