Video Speed Changer & Pitch Shifter EN

Change the speed and pitch of video or audio in Microsoft Edge — independently. Slow a solo down to 0.25× without it dropping an octave, transpose a backing track up 3 semitones without speeding it up, or watch a lecture at 2× with natural-sounding audio.

Works on media playing in your tab and on local files you choose.

WHAT YOU GET
• Speed from 0.125× to 8× with pitch preserved
• Key shift up to ±12 semitones with speed unchanged
• Both controls at once, adjusted independently
• Local file mode with WAV export for processed audio up to 20 minutes
• Live values restored when you reopen the popup on an adjusted tab

WHAT IT'S FOR
• Learning a part by ear
• Practising in a different key
• Moving a backing track into your vocal range
• Transcribing at half speed with the same pitch
• Watching videos faster without cartoonish voices

HOW TO USE
1. Open a page with audio or video.
2. Open the extension and adjust speed.
3. If direct media access is available, adjust pitch independently.
4. For full speed, pitch and WAV export support, choose a local audio file.

Speed control works broadly. Pitch shifting requires direct access to the audio stream, which DRM-protected and some cross-origin players do not allow. On those pages the extension explains that pitch is unavailable and speed continues to work. Local files always support both controls.

Free to use. No account, analytics, telemetry or media upload.
