AC-3 ACM Codec 2.2
AC-3 ACM Codec (formerly AC-3 ACM Decompressor) offers Dolby Digital AC-3 decoding for Windows ACM. Install this and you can convert/decompress AC3 audio directly to WAV / MP3 using VirtualDub. This also works with AviSynth, TMPGEnc, allowing you to use AC3 encoded AVI files, not normally recognised.
