This article tells about what is SPDIF, how Windows and sound cards work with it and how to configure AC3Filter.

Mixing matrix article described how matrix mixing works and some channel swapping magic. This article focuses on phase inverting. It describes what is phase inversion, how to test and fix incorrect phase and how to make pseudo-stereo effect from mono track.

This article describes how to watch movies at night and under poor hearing conditions (noisy environment, weak speakers). At the first sight settings for poor hearing conditions and at night must be different. In the first case we need to make sound louder, and at night we should be quiet. Nevertheless, in both cases we need to do the same. Paradox? Not really...

Remote debugging is very hard task. To track the problem a part of a file with problem is often needed. This guide tells how to cut such part.

Translation is easy! This manual describes how to make a new translation of AC3Filter or fix bugs in an existing one with help of poEdit program.

One of the most interesting features of AC3Filter is mixing matrix. With help of mixing matrix filter does downmixing and upmixing. But you can use it in much more ways: reassign channels, invert the phase of incorrectly wired speakers, mix LFE to specific channels, etc.

You may want to save the result of AC3Filter processing to a file for different purposes. For example some audio editors do not support AC3/DTS files and you may need to decode it to uncompressed WAV file. Or you may want to re-encode AC3 audio to MP3 to save some space. This article describes how to record output of AC3Filter to a file.

If you try to play a multi-channel disc on a computer in usual way (using Windows Media Player for example) without AC3Filter, you'll get just a terrible noise. Why? And how can we playback it?

I have explored a set of ac3 tracks from different movies and found that much of them contain overflows. It is not AC3Filter’s issue; other decoders also show overflows. Here we will consider AC3Filter configuration questions connected with this problem.
