AC3Filter 1.30b

Released: 2007-03-27

• AC3 loudness increased by +6dB. Now it matches loudness of other decoders. I was noted about this problem a long time ago, but I wanted to be sure what I’m doing, because new version produces overflow with LOTS of movies. I checked everything and found that it is not a bug of the decoder, but mastering issues. Other decoders also produce the same overflow at the same places. Therefore, new version works as it must work. Some notes about how to handle these overflows you may read here: AC3 overflows in movies .
• Some Vista compatibility issues fixed (matrix editing works and gains are saved correctly). But problem with SPDIF output stays. I did some research and almost sure that problem is with sound card drivers.
• A small issue with WMP fixed: sometimes it made 2 tray icons.

AC3Filter 1.20b

Released: 2007-03-20

• Now we can play multi-channel audio CD without any conversion! Just insert multi-channel CD into CD drive and open it with Windows Media Player or Media Player Classics. (Or you can use any other DirectShow media player that can playback AudioCD. Winamp IS NOT DirectShow player and does not work!)
• Also, we can playback .wav files ripped from multi-channel CD (that produced just noise before) without any conversion!
• New method of DTS over SPDIF passthrough allows to transmit DTS streams that was impossible to transmit before!
• Fixed work with 14-bit DTS files that was played back incorrectly (like fast forward).
• SPDIF input support. This will allow to decode external SPDIF source at future…

AC3Filter 1.10b

Released: 2006-10-02

Work on stability continues. Now filter shows good stability, therefore its status changes to beta and it may be recommended to replace any previous version.

Some additional work was done:

• Tray icon to access filter’s settings from players that do not allow to configure filters.
• Sometimes SPDIF mode cannot be set because of post-processing filters that do not support SPDIF output. Now it’s an additional option to force this problem. Read here for more info. (Thanks to LESAGE Aurelien for testing)
• DivX player now works with SPDIF

Known problems still not fixed:

• AC3 encode mode does not work with some receivers
• Incorrect playback of some 14bit DTS files
