Release notes:

• Localization support! Localization procedure is easy and can by done by everyone!
• Russian translation
• Fixed bug in AC3 decoder (audio skips). Thanks to Chris Meadowcroft!
• User manual fixed (broken in v1.35b)
• Mixing LFE channel into several channels preserves resulting loudness. LFE level now means gain relative to front channels.

Release notes:

• Fixed a bug in AC3 decoder (decoding of 4.1 and 3.1 AC3 files was affected). Thanks to Dietmar Kleiner for reporting and testing!
• Fixed a bug with fast playback of mono files in WMP
• Delay units works correctly in offline config utility
• SPDIF page added, all SPDIF-related options are moved there
• AC3Config utility supports themes
• Invert levels option to fix a bug with levels display in 3rd-party themes
• Default output format changed to stereo

Release notes:

• 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.

Release notes

• 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...
