TuneShift von Julious Niloy

TuneShift puts pitch and tempo controls directly beside your YouTube practice session.

Use it to transpose a song into a comfortable key, slow down a difficult passage, speed up a lesson, or match a track to your instrument without leaving the video page.

Features:

• Shift YouTube audio up or down in semitone steps.
• Choose playback-speed presets from 0.5x to 2x.
• Control pitch and tempo independently.
• Reset pitch and speed with one click.
• Switch between dark and light themes.
• Keep settings active while navigating between videos in the same tab.

TuneShift works only on YouTube pages. Audio processing happens locally in Firefox, and TuneShift does not collect or transmit user data.

Real-time pitch shifting can introduce audio artifacts depending on the source video and selected settings. TuneShift is a practice tool and is not intended to replace professional audio software.

TuneShift is not affiliated with or endorsed by YouTube.
