I'm not quite sure what provoked the desire to start converting random DTS and DVD audio CD's to WMA Pro 5.1. I'm not even sure why anyone would really want to anyway. I mean it would be just as easy to copy the entire disc 1:1 than it would be to actually convert. I suppose there was a cool and wow factor involved. It probably started from the time I first found out about
Pink Floyd - Money being released in WMA Pro 5.1. Sadly it was only for a very limited time, during which I was in England on dial-up and never noticed. I did finally get to hear it and plenty other 5.1 WMA tracks since coming to Redmond though and I'm just in love.
I try not to get into the entire stereo vs. 5.1, analog vs. digital, DD vs. DTS, and MP3 vs. WMA arguments. I just enjoy the music.
I've got a couple DTS and DVD audio CD's which really do sound fantastic but sadly any time I want to listen to them I've got to pop the disc in and that means getting up and finding it. Plus in this form it's not indexed, it's not in WMP or MCE, and it'll never get listened to regularly. To solve this I used a couple tools to backup and convert the 5.1 content to WMA 5.1.
I found one guide on the net along with some of the tools to do the process here. Granted some of it may be a bit shady but I just had to try and see if I could get a good quality 5.1 WMA out of it. The guide while extensive, missed the bits about converting from the 6 discrete mono WAV (channels) to a single WMA. To do this I used Adobe Audition 1.5 which has a great Multichannel Encoder (CTRL+E), you just add the 6 tracks to a multi-track session, pop up the encoder, set the channels correctly then encode. Sadly one tool which just refused to work for me during the night was the Windows Media Encoder, I've totally lost all faith in it.
Besides Audition a copy of InterVideo WinDVD 6 Platinum is also required. Along with DTSParser (questionable usage), Graph Edit (Microsoft no less...), WAV2WAV6, and DTS2WAV. Not to mention the two filters DTSSource.ax and WAVDest.ax. Putting everything together and after much frustration you should get something like...
The Eagles - Hotel California
Windows Media Audio 9.1 Professional
VBR Quality 75, 48 kHz, 5.1 channel 24 bit 1-pass VBR, 17.8MB
If you have a proper 5.1 set up hooked up to your computer and you've set the speaker settings to 5.1 by going to Control Panel then Sounds and Audio Devices then Advanced under Speaker settings, you should get the full surround sound experience. Otherwise WMP10 will auto down mix it to stereo... Then, well, I feel your pain. Regardless the quality is still there to enjoy.
