[QUOTE="Lotsofjazz, post: 796350, member: 64243"] yeah, I figured that out.. logical of course :) ffdshow was last updated in 2002, an Alpha release in 2004, since then development has come to a stand still. AC3filter was updated the last time end of 2009.. So what is old? :) And what Hoborg tells in his response is plain wrong, AC3filter does support HD Audio for re-encoding.. SPDIF doesnt! So that is why you need AC3filter, it re-encodes the HD audio to AC3 and sends that to SPDIF out.. and what is HD audio? most of the time only more channels (6.1 and 7.1 in stead of max 5.1 that SPDIF can support) Only DTS-HD and TrueSound provide theoretically a higher quality sound because of the higher sample frequency (SPDIF max 640) But my experience is that for richness and clarity of sound the amp itself is way more important, that is why I have still my 10 year old Marantz, which has only analouge speaker outputs and a few SPDIF toslinks for digital audio input. I have tried yesterday and the AC3filter accepts a HD DTS stream fine, and re-encodes to normal AC3 perfectly Note that AC3 filter does not realy decode the audio for me, it only re-enncodes to AC3 in case it is not AC3 already or standard DTS. I need that so it can be send over the SPDIF to my high end Marantz Home Theatre audio amplifier. I wonder if your setup also has a SPDIF connection with a seperate high end home theatre system.. I do not have the speakers directly to my HTPC and I do not want to.. Computer speakers are crap 90% of the time. But I think I understand what you do, and it might work for me as well, but I will try to achieve without SAF... What need to be accomplished is that first the audio and video is decoded, then corrected for the frame rate and then Audio only re-encoded into AC3, from what I understand from you mpaudioencoder can do that for me?. I have to figure out how to do this, but I think this should be possible without SAF, because from what I notice you only need the audio decoder of ffdshow, right? so why not install that by myself and avoid the other hassles SAF generates. As a side question, how does this affect sound? will music not get out of tune too much? I am a musician myself so I have trained ear for that unfortunately, I hear immediately when something is out of tune. We will get there, thanks :) Lots [/QUOTE]
