Blu-Ray: Compliant Audio


Dima

Question

Hello,

 

I have a 16-bit 48 KHz 1536 Kbps Stereo Wave PCM file. When I bring it into DVDIt! Pro HD, the program tells me that it's not a Blu-Ray compliant file. When I create the disc, the audio gets transcoded, and a new file (CustomAudio1.wav) is created in a temporary folder. Looking at the properties of this new file, I noticed it's exactly the same as my original - 16-bit 48 KHz 1536 Kbps Stereo Wave PCM. However, upon listening to the new file, I noticed that audio levels were significantly lower than on the original. This was confirmed by bringing both files into an audio editing program.

 

There aren't any volume/level settings in DVDIt! Pro HD project properties.

 

So, my question is, why exactly is this happening?

 

Thank you,

Dima, yours was the first report of this. I will put it in front of QA so we can explore the issue. FYI, there are audio controls on the timeline (right click on the audio in the timeline and choose audio options and then set the audio at 125% or something like that). I don't know, however, how those are working for Blu-ray burns...it might error out.

Thanks Scott.

 

My big concern is with DVDIt! not recognizing the compliant audio format. Volume level seems to be a potential unexpected side effect that I felt I should mention.

 

Let me know what you find. Thanks again.

Thanks for your help.

 

I'm surprised that such a blatant issue made it into the public release of the program. Perhaps Roxio never took the time to thoroughly test compliant audio/video formats for Blu-Ray.
