Smart Earmuffs de persistentwizard

Normalize the volume of playing media to a level you choose. Soften abrupt volume spikes or boost quiet content. Multiple fine-tuned volume adjustment speeds available. Low volume persistent mode lets deliberately quiet sections of audio stay relatively quiet. Automatic normalization mode enables normalization on new tabs when they are created.

Includes an optional overlay to let you easily monitor and adjust volume during playback.

Works with cross-origin media when the host allows it (Access-Control-Allow-Origin).

Screen reader friendly throughout, with WAI-ARIA labelled controls, full keyboard navigation, and status messages that announce themselves as they change.
