How to play 6 channel wav files from PC?

Hello everyone, I'm new here. 

I just read that is it now possible to rip the MLP tracks from a DVDA on a PC?

If it's possible, I was having some questions for you experts:

It is possible to burn 6 channels WAVs on a DVD and let the receiver do the D/A instead of my Pioneer dv563a?

What I would like to do is to be able to rip my DVDA on my PC or burn it and pass the MLP tracks directly to my receiver and do the bass managment there instead of going analog.

I will be very excited to know if from my PC I can send the high resolution stream from my PC to my receiver. 

thanks to everyone!

I am pretty sure you can't do what you want.  The only way to play 6 channel wavs as far as I know is through the analogue outs of your soundcard.  I have to do this for the hi-res copies of quadraphonic records I have made.  Neither optical or co-ax has the bandwidth.  The newer firewire based connections *may* allow you to do it I suppose but don't know...

I don't believe a 6-channel WAV can exist and that belief was strengthened by this response in cdfreaks.com found by Googling for " 6 channel WAV" :

as far as i know, a standard audio cd can only exist out of 2 channels (according to the book of rainbows). I thought that was also the case with wav-audio. For 5.1 sound you can use for example AAC."
I can report that the JVC RX-D302B internal DAC I got Friday does a fine job with any matrixed (is that the word?) multi-channel source fed from the PC via USB Wi-Fi transmitter or USB 2.0 cable.

No sorry,  6-channel WAV can and does exist.  Just because audio CDs don't support it doesn't mean anything.  I make them on a regular basis.  The common implementation is Extensible Wave Format which supports assigments for up to 18 channels. 

Matrixed?  I suspect you mean Dolby Digital and DTS which aren't matrixed sources.  Prologic is Matrixed.

It's possible to have 6 channels in a WAV, though I do not know how standard-compliant is that. I know i had some when I was ripping the DVD-Audio discs with the special ripping tools "released" a few months ago.

As for reburning, I'm not sure if you can burn them in a format that preserves the hi-res content and quality while it still works on a simple DVD player.

For my research I have even used .wav files containing 42 audio channels. Most editors like Cooledit are able to read these files.

ok but how you play the file without losing the high resolution? you need an analog card with the 6 channel output? there is no way to play the file the digital way?
thanks.

With that lead about Extensible Wave Format I readily found the freeware MavenPlayer which purports to play 5.1 channel EWF files.  However, the link for downloading sample audio files is dead.
If somebody finds that it works, could they post a sample audio file for the rest of us to try?

You can play them in foobar and I think winamp too.  Plus you can losslessly compress them with wavpack (and some of the other lossless encoders too, but not FLAC).

yes but how it will be output to preserve the high resolution of the dvd audio? by 6 analog cables? can it be sent to a processor via spdif?

Use ffdshow audio DS filter and allow PCM as input, set output to AC3. Using this method your computer will redirect your high quality multichannel PCM stream through SPDIF. I suppose that your computer has a SPDIF interface and you have an amplifier with this interface too. You just need a DS player like MPC 6.4 or the infamous WMP.

Is AC3 via SPDIF on-the-fly lossless?

It is lossy for sure since AC3 is lossy. At this time there isn't a single consumer soundcard supporting MLP output through SPDIF because of licensing problems (a MLP digital passthrough license is really expensive and it is reserved only for professional equipement) because it is technically easy to do, OTOH 6ch 96/24 raw samples does not fit in the SPDIF bandwidth. IMHO The best option you have is using the described method. Analog outputs will give you a lower SNR, coupling effects and less quality than lossy but digital AC3 IMO. Just try it and give us your feedback.

Anyway if a future hack of the drivers of a soudcard allow MLP through SPDIF, you will need a MLP thorugh SPDIF enabled amplifier.

that's what I thought. I will continue to listen to my DVDA and SACD through my Pioneer 563A for now, until I get digital way to send high res audio via HDMI or Ilink with a new player or if a soundcard arrives some day supporting those stream.

Strange. I've ripped the DVD Audio off some 5.1 DVD-A discs and encoded them to FLAC resulting in 6 channel FLAC files. Why do you say its not possible to encode them to FLAC?

Ah so multichannel FLAC does work in some fashion then...  The software I use to make  multichannel WAVs uses the Extensible WAV format which FLAC doesn't support at the moment.  I believe this is the most common form of multichannel WAVs (as there are channel assignment issues with making multichannel WAV files without using extensible WAV format (I think)).  Guess I should have been a bit clearer...

Remember that it not only depends on your computer's soundcard but also on the amplifier's digital input. If the amplifier does not support MLP, then you will still need to provide the signal through multi-analog or downgrade it to DTS or high quality AC3 (640Kbps), you should not notice the difference between pure MLP and HQ AC3, but it depends on the rest of the system (amplifier, speakers, cables, headphones, the environment, etc...).

I think I need to be walked through this slowly. 

I want to take a bunch of .wav files and combine them into a 6.1 file of some kind, and then play it over a toslink connection into my home theater. Some lossiness ok (and apparently inevitable). It sounds like if I convert the wavs to AAC format (same as AC3?) then I can do that... maybe. But downloading ffdshow didn't give me a handy interface where I can specify a bunch of .wav files in and get an .aac or whatever out. So how is it done?

Once I get the output file, how do I get it to play over the toslink connector? I'm using an external SB Audigy card and it seems convinced that if I want digital output, that I must mean 2 channel sound.

Help the newbie, please... thanks!
