I'm using Neo:6 upmix, but not from foobar. I know that there is a DTS Neo:6 DMO that is installed with Creative's Media Player (but I think you need to have their sound card) and also PowerDVD's audio decoder offer Neo:6 upmixing. Maybe there is a way to use them from foobar using foo_avs but I've never tried that.

Which speakers/amp are you using?

i 've installed Power DVD,and i could see only Dolby Prologic II,and True Theatre options for 2ch mp3 i played,no DTS Neo6 upmix
i couldn't figure out what "foo-avs" is,can you explain?
you can also suggest me an alternative player other than foobar for DTS Neo 6

I know Neo:6 has one back surround channel, but you're only running a 5.1 speaker system.

Neo:6 decoding algorithm is independent of the specific two-channel matrix encoding. Hence the input signal (Lt, Rt) can represent a standard matrix mix (L, R, C, S), a five-channel mix (L, R, C, Ls, Rs), a six-channel mix (L, R, C, Ls, Rs, Cs) or other. Reconstruction of the multichannel audio is dependent on the user speaker configuration. For example, for a six-channel signal the decoder will generate a discrete center surround Cs channel if a Cs speaker exists; otherwise, that signal will be mixed down into the Ls and Rs channels to provide a phantom center surround.

Unfortunately, I don't know of any software-only solutions. It seems most audio device manufacturers opt for Dolby features. Is there anything in particular you prefer from Neo:6 than Dolby Prologic? I know Neo:6 has one back surround channel, but you're only running a 5.1 speaker system.

Yes, of course. I use a rather old version 7 of PowerDVD. CyberLink Audio Decoder (PDVD7) have 3 upmixing choices: CLMEI-2, Pro Logic IIx and Neo:6. Maybe in newer versions they chose not to use Neo:6 anymore...
I put that decoder in KMPlayer's chain and set priority to Use forcibly. That's the way I'm using it. See the screenshot...
foo_input_avs is AviSynth decoder component by kode54 that adds decoding support for AviSynth scripts. (.AVS) But as I said, I'm not sure that one could write an avs script to use CyberLink's Audio Decoder...

The only way to upmix two channel to DTS or DD is to manually create the 24bit 6 channel mix from the best source of the two channel that you have. But if you are talking about music, then you will need all the tracks from the original recordings in 24bit then you could mix those tracks over six channels instead of two. Any sort of software based upscale of 2 to 6 is not the same in comparison. It is only an effect, they are taking two channels and using sound processing to send different parts of the audio too different channels. You can encode two channel sound to DTS and DD but that will just be two channels over five speakers and not real DTS or DD.

I have a yamaha 467 and if i want to send the two channel flac music from foobar to all the speakers i use the av receivers upscale. That upscale i think would be better than any software based upscale. But i prefer to listen to music of two channels on two channels, even though i have five speakers. But some two channels movies i will upscale them with the AV upscale. I also have an ESI maya 44 which does ac3 passthrough. I then have an optical cable going to the avr. Using ffdshow-tryouts x64 codec.

Hi Mr.Eevan,
i am not much familier with these tweaking,can you elaborate bit more,

In many cases the stereo movies and games (like on the PS2 and Gamecube) are specifically encoded for DPLII though.

For music, I do plain stereo, but if I have to choose I'd also choose Neo:6 cause DPLII(x) puts metallic sounding artifacts in the surrounds.

You're welcome!

Cheers
