I have this film, and this it how it graphs.  From about 1:33 to about 1:39, there is a strong 20Hz effect, you can see it in the average and peak graphs.  At one point it is encoded as hot as 108-109dB If played back at 'Reference Level'.  With a real low distortion playback system, it would lend an ambience to a scene that many would find disconcerting.  Low distortion 20Hz playback is rare to achieve.

Has anyone measured the content of the 1917 movie?  Near the end there is some ominous low frequency bass. Reminds me of the Hunger Games raffle scene.  Can someone measure to see what frequency range that is on 1917?

you can see it here - https://beqcatalogue.readthedocs.io/en/latest/aron7awol/59350372/

the spike is clearly visible on the heatmap view

Left hand side is the amplitude of the digital signal (with '0' at the top being the highest it can possibly go).  The bottom is the frequency.

Summarizing that graph: the loudest bass is -20dB at 40Hz, and it drops fast under that (10dB lower is about half as loud to your ears, so the bass at 20Hz is over half the volume of the bass at 40Hz).  So ultimately you will not be blown away by any part of the low end in Shang-Chi.  It's all relatively high in the frequency range, and not all that loud.

Thanks.  That's a crying shame.  Hopefully my Crowson will give me something a bit more to make this a better audio experience.
