AC3Filter is a high quality free audio decoder and processor filter that allows media players to playback movies with AC3 and DTS audio tracks
AC3Filter - it is DirectShow filter for AC3 decoding to play .AVI with AC3 audio tracks and MPEG2 (DVD). Distributed absolutely for free (FREEWARE, OpenSource). Sorry if my English is bad, but I think it is better to have something than nothing.

Main features:
  • Full AC3 standard compliance.
  • S/P DIF passthrough support.
  • Decode MPEG2 PES streams.
  • Multichannel output support.
  • LFE support.
  • Dynamic Range Compression (DRC) support.
  • Overflow control and automatic gain control.
  • Gain levels control.
  • Bitstream information (channel format, bitrate, sample rate, coupling freq and maximum freq).
  • Input/output levels.
  • Matrix mixer with direct control of mixing matrix.
  • Stereo to multichannel mixing.
  • DolbySurround/ProLogic/ProLogicII downmixing.
  • Equalizer.

The official change log for version 1.46 is as follows:
  • + AC3 encoder bitrate is now adjustable
  • + Korean translation added (thanks to starcodec)
  • ! Upmixing of Dolby Surround files works now (thanks to Stefan Schott)
  • ! MPEG Audio Joint stereo playback fixed (thanks to Daniel Bechter)
  • ! Problem with decimal point in mixing matrix on some non-english Windows (thanks to Marcin Hencz)
