Why it doesn’t play

Browsers and the built-in Windows apps can’t decode DTS-HD Master Audio. Usually you’re told to install a codec pack or buy an extension. You don’t need either.

Play it free with PlayAnyVideo

  1. 1

    Open the PlayAnyVideo player in your browser — nothing to install — and drop the file in. Files never leave your device.

  2. 2

    If the browser can’t decode it, the built-in universal engine (open-source, LGPL) takes over automatically.

  3. 3

    For the heaviest files (4K/8K HEVC, DTS, TrueHD) install the free Windows app: it converts on the fly with your graphics card and plays everything.

  4. 4

    On Android, choose “Open with → PlayAnyVideo” from your file manager or messenger.

FAQ

Is it really free?

Yes. PlayAnyVideo has no ads, no paid codecs and no locked features.

Is my DTS-HD Master Audio file uploaded anywhere?

No. Playback happens on your own device; local files are never sent to a server.

Do I need a codec pack?

No. Codec packs can break other players and often bundle adware. PlayAnyVideo brings its own decoders.
