What is a .Atmos file?
An Atmos file carries Dolby Atmos object-based surround sound, with height channels.
- Did you know
- Dolby Atmos debuted in cinemas in 2012, adding overhead channels for truly 3D sound.
- A Dolby Atmos mix combines fixed bed channels with audio objects, each given x, y and z coordinates plus size metadata so it can be placed anywhere in the room.
- The universal Atmos master is an ADM BWF - a Broadcast Wave file carrying the audio together with Audio Definition Model metadata.
- What Analyser reads
- Identify Dolby surround codecs - Digital Plus (E-AC-3), TrueHD, MLP, and Atmos - with channel-layout detection (5.1, 7.1).
- Depth of analysis
- .Atmos is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .Atmos file
- Drag a .Atmos file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
