What Does DTS/AC3/DD+ Source Filter Do?

This source filter acts as a bridge between your audio files and media players.

Once installed, it registers with Windows and allows any DirectShow-based player - including MPC-HC, MPC-BE, Zoom Player, and PotPlayer - to open and play standalone DTS, AC3, and EAC3 audio files.

Originally developed by Inmatrix (creators of Zoom Player), the filter has been updated to support modern Windows versions and the newer DD+ (Dolby Digital Plus/EAC3) format.

Supported Audio Formats

• DTS - Digital Theater Systems surround sound.
• AC3 - Dolby Digital (standard DVD audio).
• DD+/EAC3 - Dolby Digital Plus (streaming and Blu-ray audio).

For advanced AC3 processing with equalizer and SPDIF passthrough options, consider AC3 Filter. If you need broader format support including DTS-HD and TrueHD, LAV Filters is the recommended modern alternative.

How to Install DTS/AC3/DD+ Source Filter

1. Download the installer from the link above.
2. Run the setup file (administrator rights may be required).
3. The filter registers automatically with Windows.
4. Open your preferred media player and play any DTS, AC3, or EAC3 file.

No configuration is needed - the filter works silently in the background.
