## Description

Sound Amplifier is an Android accessibility Chrome extension designed to make everyday conversations and surrounding sounds more accessible for people who are hard of hearing. It enables users to filter out unwanted noise, amplify soft sounds, and focus on specific audio sources like conversations, TV, or lectures using just their phone paired with headphones.

Key features include noise reduction, conversation mode (available on Pixel 3 and newer), and personalized audio settings that allow boosting low or high frequencies or quiet sounds separately for each ear. The extension supports quick toggling through accessibility buttons, gestures, or Quick Settings. Available for Android 8.1 and up, Sound Amplifier ensures clearer hearing experiences without storing any audio data.
