What is DTS Player?
The DTS Player plays .dts audio files in your browser. Choose a file, wait for the FFmpeg decoder to load, and press play. Multichannel DTS tracks are downmixed to stereo, so the result plays on any headphones or speakers.
How does DTS Player work?
DTS (Digital Theater Systems) is a surround sound codec used on DVDs, Blu-rays, and cinema releases. A raw .dts file holds the audio stream without a video container. Browsers cannot decode DTS, so this tool loads FFmpeg compiled to WebAssembly, decodes the stream with the dca decoder, and converts it to 16-bit PCM for the Web Audio player.
Surround layouts such as 5.1 are downmixed to stereo and resampled to 44.1 kHz before playback.
Key Features
- Decodes DTS with the FFmpeg dca decoder
- Downmixes 5.1 and other surround layouts to stereo
- Accepts raw .dts files extracted from discs
- Output is 16-bit PCM at 44.1 kHz
- Play, pause, and seek controls
- Decoding runs in WebAssembly on your device
Common Use Cases
Check a DTS track ripped from a disc
Listen to an extracted .dts track to confirm the right language or mix before you archive it.
Open a DTS file on a computer without a DTS decoder
Play .dts files on macOS or a browser-only machine where no media player handles DTS.
Preview a DTS file before converting
Confirm the audio is intact before you convert it to a format such as MP3 or WAV.
Audit a home theater rip
Spot-check dialogue and music levels in a downmixed copy of a surround track.
How to Use This Tool
Choose a DTS file
Click the upload area or drop a .dts file onto it.
Wait for the decoder
The first file loads the FFmpeg WebAssembly binary from a CDN. Later files in the same session start faster.
Press play
Start playback to hear the decoded DTS audio.
Pause or seek
Use the player controls to pause, resume, or jump to another position in the file.
Pro Tips
- 1
Extract the audio from a disc image or video file first. This player takes standalone .dts files, not whole movies.
- 2
If a file will not open, check that it is a DTS stream and not a renamed AC3 or WAV file.
- 3
A 5.1 track folded into two channels can sound different from the surround original, especially in dialogue and effects balance.
- 4
Large DTS files take longer to decode before playback starts.
- 5
Use the AC3 Player for Dolby Digital tracks, which are a different codec.
Frequently Asked Questions
How do I play a DTS file on my computer?
Open the DTS Player in a browser, choose the .dts file, and press play. No media player or codec pack is needed because FFmpeg decodes the file in WebAssembly.
Why do 5.1 DTS tracks play in stereo here?
The player downmixes every file to two channels so it sounds correct on ordinary headphones and speakers. The original surround mix is not changed because nothing is saved.
What is the difference between DTS and AC3?
Both are surround codecs from different companies. DTS usually runs at a higher bitrate than Dolby Digital (AC3) and is decoded by a different FFmpeg decoder.
Does the player open DTS-HD Master Audio files?
It plays standard .dts streams. DTS-HD content stored in a Blu-ray container needs to be extracted to a standalone audio file first, and results depend on what FFmpeg can decode.
Can I save a DTS file as MP3 or WAV?
This tool plays audio only. Use a converter if you need a different format.
