I'm certainly no expert in 5.1 but when I look at that waveform, I see the center channel is much busier than all the others which could very well mean the dialog is being overpowered.
The idea of the waveform is to show that the center channel is not lower than the L/R channels, which would result in it being drowned out. The fact that it was at a level equal, or better, then the L/R channels should keep it from being drowned out. The waveform is indeed subjective, but it is one reference point.
The center channel, IMHO, was not being overpowered. Keep in mind that the waveform was highly compressed time-wise. I was thinking of showing some sections of the waveform in order to show more detail.
But were you specifically listening to the center channel? Were you listening for muffled dialog that was over powered by music, surround effects, and loud booming bass? If so, why were you listening for that? If not, would you really have picked up on it?
For the Nashville
program, I specifically listened to the center channel by itself to make sure that it wasn't having an issue before getting "mixed" with the rest of the audio. As mentioned in the posting, I did a specific mix where I did a stereo mix of L/C/R and listened to it for any issues (issues can be considered problems
) and heard none.
As for other ABC west feeds, the listening was of the 5.1 that I created from the 6 mono channels.
I have to ask... are you sure the surround levels on your amp are set correctly, in that the center speaker is not set lower than the L/R speaker outputs?
