Version 2.1 (December 22, 2011) Hide changelog Fixed an uninstall problem specific to 64-bit Windows. Added experimental support for tag WAVE_FORMAT_EXTENSIBLE. Version 2.0 (December 21, 2011) Added decoding support for low sampling rates (BSID9 and BSID10). Fixed some install problems specific to Windows 98. Version 1.9 (July 16, 2011) Fixed a decoding bug in AMD64 build when source is stereo. Combined 32-bit and 64-bit assembly code into one module. Version 1.8 (July 9, 2011) Fixed corrupt MMX decoding when source is 5 channels. Fixed silent audio on AMD64. Version 1.7 (July 2, 2011) Updated .inf and .bat files provided by ale5000. If you are using one of the batch files to install the codec on Windows Vista or higher, you must right click the .bat file and select "Run as Administrator". Version 1.6 (March 19, 2011) * Major rework of Visual Studio workspaces, but no significant code changes. * Moved registry storage location to HKEY_CURRENT_USERSoftwarefccHandlerAC3ACM * New .inf and .bat files are provided courtesy of ale5000. Version 1.5 (January 17, 2010) * I've ported the code to Visual Studio 2005 and added a new (untested) 64-bit build. Installation instructions are in ReadMe.txt. * I've switched to using 7-Zip to archive the source code package. Version 1.4 (September 22, 2007) * Fixed an A/V sync problem when encoding 44100 Hz AC-3. * If you insert AC3ACM into a DirectShow filter graph as an AC-3 encoder, it chooses a default bitrate based on the number of source channels. The default is (96 * nChannels) kBit/s. I've added an option in the driver configuration dialog which allows you to change the default to (64 * nChannels). Version 1.31 (May 13, 2006) * Fixed an MMX bug in the decoding of 3/2 channel AC-3. Version 1.3 (May 11, 2006) * Added support for WAVEFORMATEXTENSIBLE PCM input for encoding. * Default channel order for PCM input and output has been changed to FL,FR,FC,LF,BL,BR in accordance with Microsoft's recommendation. * Added an option to disable MMX in the driver configuration dialog. Version 1.21 (April 17, 2006) * Added the fix from FFmpeg for a low volume issue in ac3enc. Version 1.2 (October 22, 2005) * Added sensible strings to the ACM encoder configuration dialog. Version 1.1 (September 27, 2005) * It turns out that AC-3 decoding was slightly broken in the previous version 1.0. This version 1.1 should be much more stable. Version 1.0 (September 22, 2005) * I've finally added AC-3 encoding support by adapting the "ac3enc" code from the latest ffmpeg. There is a LOT of room for improvement in the future, so don't expect too much at this stage. (Right now I'm just happy when it doesn't crash...) Version 0.9 added the humble beginnings of a configuration dialog Version 0.81 fixed a failure to recognize AC-3 in some AVIs Version 0.8 stereo downmix of surround channels was b0rked version 0.7 fixed install goof in Win98 (nothing serious) version 0.6 fixed a bug where FL/FR channels were swapped version 0.5 channel order is now FL,FC,FR,BL,BR,LF version 0.4 updated liba52 code from latest CVS version 0.3 fixed uninstall problem in WinXP version 0.2 fixed most of the bugs in 0.1 version 0.1 buggy first release

I was having an audio problem with one concert video using LAV Audio decoder. I switched to AC-3 ACM and the audio now plays perfect.

This is a great little program. It couldn't be simpler, and with good results. No doubt there are better programs, but for the money (which is none!) the results are good. I use it in conjuntion with ProCoder (which doen't output to AC3) and Encore to create good quality DVDs. Only down side is it can only handle 2 channels and you can't seperate them to output two single channels.

I didn't think this codec would be of any more use than several others I tried, but I am very HAPPY to say I was wrong. It worked great! And it works with virtualdub which has been an invaluable tool! THANKS SO VERY MUCH!

Work with ac3 sound as if it were any other format! If you deal with ac3 at all, you need this tool. KUDOS to fccHandler!

If you ever wondered why your mpeg2/vob video imported to Virtualdub has no sound, this is your answer. You´re lacking the AC3 ACM Decompressor. Get it. it´s vital.
