AC3Filter is high quality freeware DirectShow audio decoder and processor filter used to decode audio tracks in movies (DVD, MPEG4 and others). It has a priority on wide functionality and convenient settings.
AC3 Filter can decode following audio formats: AC3 / DTS / MPEG Audio. It also supports multi-channel and digital (SPDIF) outputs.

Features of AC3 Filter 2.6:

• Playback:
- Watch movies with AC3 and DTS audio tracks
- Listen multi-channel (AC3/DTS) AudioCD
- Playback WAV files with AC3/DTS content, ripped from multi-channel AudioCD without any conversion of these files.
- Playback raw .AC3 and DTS files (with help of AC3File filter)
• Process:
- Up-mix any audio track (even plain stereo) up to 6 channels
- Down-mix any audio track to any number of channels (to match your speaker configuration)
- If you have an external Dolby ProLogic decoder, you may use ProLogic down-mix to help DPL decoder to extract surround information
- Watch movies under poor hearing conditions (noisy environment, weak speakers, ...)
- Decrease dynamic range to watch movies at night
- Apply time shift to the audio track to synchronize audio with video.
- Adjust gain of every input/output channel independently to compensate loudness differences
- Adjust time delays for every channel to compensate different distances to loudspeakers.
- Passthrough AC3 and DTS over SPDIF without any change to external decoder
- Encode any audio to AC3 and transmit it over SPDIF
- USB sound cards supported


- Audio Codec Tag 2000 may be requested when AC3 Filter is missing.

- It also solves AC3 DVM codec missing, reported by AVIcodec utility.
