Clean Pitch

Independent speed and pitch controls for any video or audio, with a stable no-crash connection.

Clean Pitch adds a small floating control bar to any page with video or audio, letting you change playback speed and pitch independently — speed up a lecture without the chipmunk voice, or shift pitch for practice without changing tempo. WHY CLEAN PITCH Most speed/pitch extensions either freeze on connect, or quietly override browser internals in a way that breaks your other extensions. Clean Pitch was built specifically to avoid both: - Stable by design — every connection has a timeout and a visible retry, so it never gets stuck "connecting" forever - Plays nicely with others — Clean Pitch never touches the console or any global browser object, so it won't conflict with your other extensions - Works everywhere — any standard <video> or <audio> element, not just one specific site FEATURES - Speed control from 0.25x to 3x, free and unlimited - Independent pitch shift from -12 to +12 semitones — change tone without changing speed, or speed without changing tone - Draggable, collapsible floating control bar that remembers its position per site - Keyboard shortcuts for speed, pitch, and reset (customizable with Pro) - Save your favorite speed/pitch combinations as presets (Pro) - Zero account required, zero data collection, everything stored locally in your browser FREE VS PRO Speed control is free and unlimited, always. Pitch control is free for your first 50 uses — plenty to try it on real videos and podcasts — then a one-time Pro unlock gives you unlimited pitch shifting, saved presets, and custom shortcuts. WHO IT'S FOR - Language learners slowing down videos without the distorted, deepened audio - Musicians and singers practicing by ear who need to shift key without changing tempo - Podcast and course listeners who want faster playback without the "chipmunk" pitch - Anyone who's been burned by a speed/pitch extension that froze mid-video or broke their other extensions PRIVACY Clean Pitch doesn't collect, sell, or share any data. There's no analytics, no tracking, no ads. The only network calls are: (1) verifying a Pro license key with Gumroad when you choose to activate one, and (2) an entirely optional feedback form if you ever uninstall.
