Ac3filter Real Time Encoding
Posted on by admin
Hi i have been having this issue for quite some time now and i haven't been able to find a good answer. I know others have had the same problem but no outsiders seem to understand what is going wrong and they give completely useless suggestions.
The problem is, for some reason the fiber optic output that i am using to connect my Asus Rampage III Extreme to my receiver cannot be configured as a 5.1 setup. in 'playback devices' in windows, the 'configure' button is disabled, preventing access to the wizard that allows you to change from stereo to 2.1, quadrophonic, 5.1 and 7.1. the same is true in the Realtek manager. the screen showing the speaker configuration in the room is not present. I know for sure that the output is capable of sending 5.1 because when i go to playback devices, select realtek digital output (optical), click properties, and go to the supported formats tab, if i test the DTS or Dolby Digital encoding the sound is played perfectly through all 5 speakers.
Now to avoid confusion, i am not asking how to get 2 channel music to play out 5.1. i really don't care about music right now because my receiver has an enhancing function.
also please don't tell me that only applications with DTS or Dolby digital encoding will output 5.1 because i already know that. however VLC, PowerDVD 10, Divx, and Crysis 2, which all support either of those encoding formats will NOT play 5.1 (in the case of the media players i listed, i tested them with either a bluray or a digital copy of Avatar).
the way i have everything set up (which has the above problem) is i am currently running HDMI from my graphics card to my TV, and optical from my motherboard to my receiver. i want that option to work because the only alternative is running HDMI to my receiver, then HDMI again to my TV. with this option the 5.1 works perfectly, however routing the video signal through my receiver creates a tiny delay that is unpleasant in Crysis 2.

Real-time AC3 encoding for multichannel SPDIF output If you select SPDIF in the main ac3filter properties, it will passthrou if it is an ac3 source and it will encode to AC3 if not. But in my system, in ac3 encondinf mode, the filter stop after some seconds, it seams to be a bug. DTS® Interactive - a real-time 5.1 channel encoder that takes 2 or more channels and encodes them into a DTS bit stream - DTS® NeoPC - an up-mix matrix that turns any 2 channel audio into 7.1 channel surround sound - Dolby® Digital Live(AC-3) real time 5.1 channel encoding bit-stream to facilitate the connection with CE AV receiver.
