Everything you need to know about using this tool effectively

What is AC3 Player?

The AC3 Player lets you play Dolby Digital AC3 audio files directly in your browser without installing any Dolby decoder software. AC3 is the standard audio codec for DVDs and broadcast television. Playback runs locally using FFmpeg via WebAssembly, so your files stay on your device.

AC3 (Dolby Digital) is a multichannel audio codec developed by Dolby Laboratories, used as the standard audio format for DVD video, North American broadcast television, and early Blu-ray releases. Browsers cannot decode AC3 natively without a Dolby licence. This player uses FFmpeg compiled to WebAssembly to handle decoding directly in your browser.

Frequently Asked Questions
Why can't browsers play AC3 natively?

AC3 is a licensed Dolby format. Browser vendors do not include AC3 decoders because of Dolby's licensing requirements. This player uses FFmpeg WebAssembly to decode AC3 without a Dolby licence.

Will I hear surround sound when playing AC3?

No. Multichannel AC3 is downmixed to stereo for browser playback. To preserve discrete surround channels, use a dedicated media player that supports AC3.

Is my file uploaded to a server?

No. FFmpeg runs in your browser via WebAssembly. Your file is decoded locally and never sent to any server.

Why does playback take a moment to start the first time?

The FFmpeg WebAssembly binary needs to load from a CDN. This takes a few seconds on first use. Subsequent files in the same session play immediately.

Can I convert the AC3 file after listening?

This tool is for playback only. Use the AC3 to WAV or AC3 to MP3 converter to save the audio in a different format.
