AC3Filter 0.70b – Audio / Video Filter Plug-in

Posted in Fun Stuff, Windows


This plugin is very handy for some codec that does not perform well when playback some encoded movie files, such as DivX or Mpeg. AC3Filter is a DirectShow filter for AC3 decoding to play .AVI with AC3 audio tracks and MPEG2 (DVD). Though this may be an old release, but it’s a good as the latest available.

This is a free (open source) distribution, but it is as good as any other audio/video filter plugin that you can get elsewhere. For instance, if your .avi playback allows you to hear the background sound, but not the narration of the casts, then this may fix your problem.


  • * 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 maximun freq).
  • * Input/output levels.
  • * Matrix mixer with direct control of mixing matrix.
  • * Stereo to multichannel mixing.
  • * DolbySurround/ProLogic/ProLogicII downmixing.
  • * Delays for each channel.
  • * Equalizer.

    Hey, guys, help the girl, please =) question about mp3 players..
    i’m looking to buy a new mp3 player and i cant decide between the ipod video 30gb and the creative zen vision:m 30gb. my ipod 4g is out of space and i wanna upgrade to a 30gb mp3 player. video isnt really a concern, since i wont watch movies or anything. i just want good audio quality and a stable player. it seems like with my current ipod, i have to reset it often since it freezes up. any other suggestions are also welcome. budget is around 300$, thx
