5.1 ASF -> 5.1 AC3 or 6x 1.0 WAV?

[pelmen]

I've been trying to find out if there is any way of converting a 6 channel ASF audio only file into either a 6 channel AC3 or 6 mono WAVs. Anyone know of a utility to help?

I don't want to try playing and recording a "what you hear" WAV file, i'd prefer to be able to convert digitally to a format that I can process (clean up, normalise, etc) as lossless as possible.

thx

Well, if you can play back the file in a directshow media player, you could use GraphEdit (doom9 download page) and replace the sound renderer with a wav dest filter and then a file writer; assuming the splitter/decoder filters are set up to playback in 5.1 mode, this would give you a six channel wav you could edit and then encode to AC3.

am hoping for a better solution. i can never be sure that all the channels are staying in their correct places when using pla/record methods. look at the stereo to 5.1 thread and all the different channel orders different methods produce. plus since everything i play on my system my audigy card spits out at 5.1 i can't be certain that a play/record method isn't being manipulated by the audigy card. i feel safer if there is a straight file conversion option. perhaps besweet might support asf file one day and solve my problem? :)

I have the same problem. I'm trying convert 6ch audio stream from Windows Media 9. If I use Graphedit, it decodes only 2 channels (i think, that this is Dolby Surround), but i need decode all channels.

So I use Foobar 2000, and convert WMV to 6ch 32-bit Float WAVe. This WAVe can be encoded to AC3 via BeSweet. But I have problem to assign right channel order. When I encode to AC3, channel order is different.

I need know the right WMV 9 channel order. Anyone help?
Thx very much.

The channel order is: Front Left, Front Right, Centre, Sub, Rear Left, Rear Right.
