How to Use:
To use the extension, download an audio file that your browser can't play due to unsupported codecs and drop it into the audio player. You can obtain sample AVI or FLV files for testing using a specific website (https://webbrowsertools.com/test-download-with/).

Technical Notes:
The extension uses the decoder section of the FFmpeg library, enabling it to decode various audio codecs.
It uses Emscripten to compile FFmpeg into WebAssembly (WASM), making it compatible with web browsers.

This extension is a handy solution for users looking to play a wide range of audio formats directly within their web browser, even when their operating system restricts the installation of native media players. It provides extensive format support, advanced features, and native integration for an enhanced user experience.
