AC3 Filter 1.60b

AC3 Filter 1.60b is designed as a professional program for AC3 decoding used to play AVI with AC3 audio tracks and MPEG2. It is distributed absolutely for free (FREEWARE, OpenSource).

AC3Filter is a high quality free audio decoder and processor filter. It allows 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.

Major Features:

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.
   • Playback raw .AC3 and DTS files (with help of AC3File filter)
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
   • Encode any audio to AC3 and transmit it over SPDIF
   • USB sound cards supported

Enhancements:

• Major change in this version is x64 support.
• Now filter is distributed in several editions: Full, Lite and Win9x. More about the difference.
• Much work with equalizer. Now you can work with each channel individually and with all channels at once. You can see the equalizer's real frequency response, and build your own equalizers with custom frequency bands up to one hertz precise.
• Spectrum is now synchronized with audio playback. Also, you can see the spectrum of individual channels.
• Translated to Greek (thanks to thanks to Peter Perdik and Dimitrios Topouzidis) and Slovenian (thanks to DarkHand).
• Installer is localized now.
