Free ac3 dts software for windows

AC3 Filter 1.63b is considered as a high quality free audio decoder and processor filter allowing media players to playback movies with AC3 and DTS audio tracks. Also it can process any audio track, much of processing options allows to adjust the sound in almost any way.

It is possible to upmix any audio source to 6 channels. Filter can do multi-channel and digital (SPDIF) output. It can encode any audio source to AC3 on-the-fly and send it over SPDIF to the receiver.

1. Playback:
   • Watch movies with AC3 and DTS audio tracks
   • Listen multi-channel (AC3/DTS) AudioCD
   • Playback WAV files with AC3/DTS content, ripped from multi-channel AudioCD without any conversion of these files.

2. Process:
   • Up-mix any audio track (even plain stereo) up to 6 channels
   • Down-mix any audio track to any number of channels (to match your speaker configuration)
   • If you have an external Dolby ProLogic decoder, you may use ProLogic down-mix to help DPL decoder to extract surround information
   • Watch movies under poor hearing conditions (noisy environment, weak speakers, ...)
   • Decrease dynamic range to watch movies at night
   • Apply time shift to the audio track to synchronize audio with video.
   • Adjust gain of every input/output channel independently to compensate loudness differences
   • Adjust time delays for every channel to compensate different distances to loudspeakers.
3. SPDIF output:
   • Passthrough AC3 and DTS over SPDIF without any change to external decoder
