SidePlay - Spatial Audio Controller

Lightweight Chrome extension for precise control over spatial audio. Isolate tab audio to left or right channel with a single click.

SidePlay lets you choose which ear plays a tab's audio: left, right, or both. Click the SidePlay icon in the toolbar and pick one option: • Stereo: both ears (default) • Left only: the left channel plays in your left ear • Right only: the right channel plays in your right ear Typical use: set one tab to Left only and another tab to Right only, then play both. You hear each tab in a different ear, for example a lecture in one ear and music in the other. Private by design SidePlay changes the audio routing inside the page with the Web Audio API. Everything runs locally in your browser. SidePlay does not collect, store, or send any personal data. Good to know • The setting applies to the current tab. The audio returns to Stereo when the page reloads. • Tabs that were already open when you installed SidePlay need one reload. • Chrome pages (chrome://) and the Chrome Web Store cannot be controlled.
