AC3Filter - AC3 and DTS Audio Decoding
With a large percentage of new camcorders using MPEG-2 video combined with AC3 audio as a common storage format, it's become much more complicated to work with camcorder video. If you have one of these camcorders and use free tools like Windows Movie Maker for video editing, you simply shouldn't be without the free DirectShow filter AC3Filter. The app runs in the background as an audio decoder and processor filter for AC3 and DTS audio tracks. AC3Filter supports playback of AC3 and DTS audio tracks in software like Windows Media Player, in addition to enabling editing features in things like Windows Movie Maker. Audio processing supports an up-mixing any audio source to 6 channels or down-mixing to stereo from surround sound. Both analog multi-channel and digital (SPDIF) output are supported. AC3Filter encodes any audio source to AC3 on-the-fly and send it over SPDIF to your receiver. [Windows 2k/XP/Vista $0.00]
