Well you’ve seen an EQ before? This is like an extension of EQ it sees deeper down the spectrum, well blow our hearing where its mostly felt, if amplified at insane levels it would be heard, but it would painfully uncomfortable.

So in general you’re looking at the frequency response of what the films producing from the LCRS folded together as Dolby stereo mixes don’t have true sub bass discrete signal.

So I take you’ve seen Star Wars more times than you’ve had hot dinners?

The musical score opening is bit scattered apart on this CLV laserdisc. The CAV THX laserdisc is bit fuller wider in the lower register.

It’s easier if you had the program running on your pc. Its simple to load up and takes few minutes to set the parameters and its fairly effective.

The green is like soft level

The yellow getting a bit higher in level

The red getting hotter and louder

The pink too loud or represents the highest peak in the frequency.

Note the third graph the pink is the death stars low humming energy reactor sound, or what ever? The traces of colours below are the, star destroy. Its easier to turn the level up, and the, star destroy might produce some pink! Then the death star will sound too LOUD at 43Hz.
