What am I gonna do with you?
So, is pink noise down 3dB/octave on a SL waterfall graph or is it down -50dB/octave as your posted graph shows? And, dunno what scene you capped but the 500 Hz content in that scene is obviously non-existent. No calibration you could dream up will put the content down -120dB and still call it content.
I did not say SpecLab is calibrated to ELC, I said that all mixers have ELC built in to their hearing, thus the low end mix will be reflected in the SL caps... which it is.
You imported the PH graph into REW and "I also changed the frequency axis to logarithmic (each octave approx. the same width)." That's ALL you did. The graph is identical otherwise. Distorting the graph to "logarithmic power density" assumes anyone would believe there is higher SPL content at 160 Hz in WOTW than there is at 30 Hz. Good luck with that suggestion.
BTW, with the settings used in that SL cap, full bandwidth waterfalls aren't possible.
Please do this:
Play a 10 Hz sine tone through the REW tone generator into SL. Next, repeat the process with a 100 Hz sine tone and then repeat once more with a 500 Hz sine tone and post the SL graph. Then explain why those equal level sine tones all show exactly the same level in SL, but a movie soundtrack cap needs to be tilted?
Now, on to this absurd idea that a PB13 can accurately reproduce WOTW at 118dB in-room or on any planet in this universe...
You post Josh's max compression sweep trace, add my room gain profile data and wham, WOTW at reference level (from 14 Hz up).
You forgot to include some data in that wet dream:
First there's this little snag when pushing the Ultra that hard:
What's the distortion level below tune at that level? We can't say... it's off the chart. But, we can say it's very high and certainly audible.
What happens below 10 Hz? We can't say, there's no data because there was no input signal, much less a complex signal spanning 5 octaves.
And how closely does a max output sine sweep or a tone burst at any point in the bandwidth equate in maximum output to an infinite spread of -5dBFS simultaneous frequencies across 5 octaves? Well, we do have some data to venture a guess:
There are only 10 frequencies in this "effect" and they range from 92dB-102dB, yet they sum to 110dB and create all sorts of squiggly things above the noise floor.
Casting no aspersion on John's efforts, peaks are tricky things to measure accurately. You assume the maximum peak in WOTW is 115dB and you assume that 115dB is the only requirement from the sub at 2 meters distance with room gain to accurately reproduce the soundtrack at your seat and you assume that a sine sweep accurately approximates the extremely wide bandwidth and infinite frequency effects found in WOTW.
If you prefer to lop off 2-1/2 octaves of WOTW, tilt it's graph and fantasize about a PB 13 providing accurate reproduction at the seats, be my guest. You won't be alone in that fantasy around here. For myself, I'm gonna hafta pass on that one due to overwhelming evidence to the contrary.
