About this extension

AudioShift lets you manipulate the audio output of music and video platforms directly from your browser.

Features:
- Speed control — slow down or speed up playback from 0.5x to 3x in 0.05x increments
- Tone effect — shifts the audio tone using playback rate compensation (affects pitch and speed together)
- Randomise — instantly randomises speed and tone for a fresh listening experience
- Per-tab settings — changes apply to the active tab only and persist across page reloads
- Power toggle — bypass all effects instantly without losing your settings

Supported platforms include YouTube, Spotify, SoundCloud, Tidal, Deezer, Apple Music, Bandcamp, Mixcloud, Audiomack, Pandora, Last.fm, Twitch, Vimeo, Dailymotion, Netflix, Prime Video, Disney+, Hulu, and Max.

Note: Independent pitch shifting (decoupled from speed) is planned for a future update.
