Play Dolby AC-3 audio using the <audio> tag

This demo showcases browser-based decoding of Dolby AC-3 audio using a WebAssembly pipeline. Since most browsers do not natively support AC-3 due to licensing constraints, this solution uses a WebAssembly version of the decoder to make playback possible without plugins or server-side conversion.

As of the publication date, this format is not natively supported by Firefox, Chrome or Safari.
