This is very good quality, but becouse we need to passthrough it as 5.1 we need to proceed it more and standartize it.Here is time for FFDshow. FFDshow resample anything that is <> 48Khz to 48Khz, then on the fly encode it to 5.1; 48khz AC3 16bit.48khz AC3 16bit is "standard" - all recievers should be able to handle this format.Of course there is no need to AC3 encode, you can output it as it is now as 5.1 48Khz 16bit PCM.This process happend with all 5.1 (and more) audio formats - AAC, WMA, etc...But if you try to play my sample in MePo, graph is created like this: (exactly, FFDshow is missing).<img src="http://hobring.esero.net/saf/mp/graph/flac2.png" alt="" class="fr-fic fr-dii fr-draggable " style="" />By some reason, MePo blocked FFDshow, so such audio source cannot proceeded correctly.So that is why FFDshow audio decoder needs to be added to MePo video postprocessing to force load it - but this cause issues for some videos with multiple audio streams inside (MePo popup cannot play...)I do not known how much tourettes wants to develop his filter, but i think to have standartise input is very usefull and can prevent lot of problems.</blockquote>
