Product summary

Review the store description, core capabilities, and common use cases.

Etude adds a musician's practice controls to online video.

- Transpose to any key and fine-tune pitch in cents.

- Slow down (or speed up) while keeping the pitch, so you can drill a fast passage.

- Loop an A-B section and save named loops per video.

Audio is processed locally in your browser. No accounts, no tracking, nothing is uploaded. Works on YouTube and other standard HTML5 video.
