Dolby-Prologic Filter for Media Player Classic ?
Howdy yall, I recently got my self a 5.1 speaker system, (Logitech z5500 ) and have been messin around with various configurations. I have opted to bypass the the on-board dolby/dts decoding and use my sound card through the 6 analogue channels cause I got a kickass Creative soundcard with a 10 band equalizer.
Anyhoo, MPC Home Cinemas inbuilt dts and dolby decoders do a dandy job splitting the sound up but when i play 2 channell anything it just goes to front left and right. I can enable Pro-Logic on the speakers but I would really prefer it if I didn't have to switch it over all the time. Also, my sound card has Creative CMSS-3D which is basically not very good. Is there a filter I can that will take 2 channels and decode them into 5.1 using the actual ProLogicII algorithims ? Also preferably, one that will let 5.1 go through untouched ? |

Use Ac3Filter or ffdshow and configure it to
1) Output 5.1 channels 2) Process uncompressed audio

I tried ffdshow, I found setting to use 5.1 speakers, but they didn't work, I could never get anything besides audio from front left and right.
AC3Filter at least decoded to all 5 channels, but it wasn't very good at all, dialogue was very much spread across the three front speakers. Any suggestions on what I might be doing wrong with ffdshow, I told it I had 5.1 speakers in the Mixer settings and also tried checking Dolby decoder, but I got nothing (at all) from the centre speaker and or the two rears. I am not sure what you mean by this Last edited by jonathonsunshine; 21st July 2008 at 00:29. |

And it means that ffdshow-audio can be used as a "post-processor" for other audio decoders...

In ffdshow you must also enable the "Dolby Decoder" filter to get 5.1 audio from a Prologic-encoded stereo signal

In the best case the "Dolby Decoder" will pass-through 5.1 audio untouched.
In the worst case it will discard the center/rear channels of 5.1 audio and then decode multi-channels from the right/left channel. I didn't try it yet
