Hi,

I know there is a really good tool (azid) to convert AC3 to a 2 channel Dolby Surround compatible WAV file. Now, in case I have such a WAV file containing such a 2 channel Dolby Surround stream, is there a utility that decodes this stream to the seperate audio streams for the seperate speakers? This would be a software behaving like the decoding circuits inside a Dolby Pro Logic Decoder. Does anybody know, whether such a software exists?

Thanks in advance,
JohnDie

Dolby Pro Logic is built into almost everything... why would you need software to do it?

actually, if you have a 2 channel AC3 contianing DPL encoded material, the ntervideo encoder will play it back through multi-speakers, even without DPL hardware.

About any Software DVD player can do it (PowerDVD and WinDVD, for example).

To get the intervideo (=WinDVD) directshow-filter to decode to multi-channel can be a bit tricky and doesn't work sometimes (Pro-Logic costs a lot of licence fees and is disabled for applications other than the actual DVD player).
But then, you can get the Moonlight Odio Dekoda Directshow filter which decodes about any kind of files to any amount of channels that you like :)

hmm .. searched .. found about 10 messages with the same question and 30 of the same reply .. not one reply acctully produces 4 or 6 wav files from a prologic encoded 2 chan wav/ac3 ... i've been able to listen to pro for years now .. but their seems to be no filter that will seperate the file into it's parts.

I think we all misunderstood your first post: I thought you wanted to play back Pro Logic files, but actually you want to seperate the file into single wave files, right?

Well, if anyone knows how to do this, I guess it'd be DSPGuru :)

IMHO, only PowerDVD XP v4.0.0.1109 can decode .AVI files with DPL2 Soundtrack.
