A Jedi’s frequency waterfall response

Well it’s been a while since, I was here last. I think 2 years?

These are frequency waterfalls showing the strength of the Star Wars films. Regrettably I only have few of the originals on laserdisc. The DVD doesn’t really count I guess, unless one of you request a waterfall from a specific moment from the film.

I’ve taken liberty of doing Return of the Jedi. The laserdisc is early 1990 edition widescreen with digital PCM and analogue track.

Thou its not practical to do the whole film as it would take me, many hours to edit the size of the waterfalls and upload them and so and so on.

So a few short moments will suffice I think…unless of course of get the strength to do the whole film as it would make for some interesting fact.

The lows have been taken off my AVR Kenwood KRF-X9050D THX select sub bass output. AVR is set at 0db plus I’ve just boasted the sub bass gain by +10db to sparkle it up a little bit.

I’ve stopped the laserdisc at 5m 16s to get some feedback. Well I’ve placed a (memory repeat) at (5m 16s).

The waterfalls again show the strength of Jedi Knight, no I’m lying, they just show the strength of the signal.

 The soft green is low strength the yellow is mild red high pink very high. Not Jedi has a few pink spots in these few graphs. The software I’m using is called Specturmlab that was designed for radio amateurs. Its also found use in recording sub bass or LFE.1 and so on.

20^th Century Fox Fanfare introduction  

John Williams Star Wars theme opening

Star destroy thunders with wide range while other effects are Death Star interior and shuttle craft dropping off Darth Vader some parts are musical score as well.

The ramp lowers on the shuttle Vader steps off the platform. It ends at the top where part of it is score, it than cuts to Tatooine where I stop the laserdisc.

Oh, hey, I remember you. Welcome back. Shame I don't have anything to add to this conversation.

lol oh, please I don’t want to be reminded about that, I’ve had nightmares about it ever since.

 Thank you, it’s nice to be back after, I figuring out what the heck my password was, took me, 20 min, had to reboot for new password, sigh.

 Well have since been looking at Jedi on THX CAV, obviously it goes lower and higher up in the range. Presently looking at Empire THX CAV with few special modifications on the parametric EQ tocut a few peaks bump up the lower 20Hz a tiny bit, the waterfalls looking devastatingly low.  

Jedi reached down to below 15Hz thou very shy it was mostly (green) while it was hotter down to 30Hz which seemed to be the common limit while few tiny (yellow) spots came around 25Hz. That was the CLV version of the above laserdisc.

The CAV THX edition lower!

Empire is easily making 20Hz still waiting to see hot red or maybe some insane pink.  

Empire is still regarded as (best of the trilogy and the best sounding one) I’ve heard since Star Wars.

Tell me what I'm looking at?

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.

The asteroid slug creature scene in Empire CAV THX goes low down to 20Hz and below to 15Hz and it takes an insane sub to take the stick at that level. Or you can get away with some bass shakers stuck underneath your sofa and rattle, your teeth out! lol

I’m looking for the lowest and highest while modifying the parametric EQ while bumping up the AVR by +3db more I’m at the ceiling level on my AVR at the moment.

I use the parametric EQ Behernger BFQ2496 to force some extra low on the lower 20Hz to see how far it will stretch too. I’ve trimmed some of the common 30Hz to 40Hz and 50Hz down a bit, I have the bypass button if I want to divert back to normal readings.

I seem to recalling reading an article that the team at Skywalker sound was impressed with the new sound system that was installed. They heard lower lows on Empire that they didn’t hear on the original dubbing stage.

Empire does have some brutal low end grunt for 29 year old film. It’s really too bad I misplaced the article, I think I lost it while reading it at the beachside many years ago.

Yes my, lord we’ll find them.

Don’t fail me again, admiral.

Onto the forth side now!

Animated GIFs are still allowed in sigs (see this post). However, we decided to limit the file size to 100KB or less.

Jedi Temple34 - yours is nearly 500KB. Please could you remove it or replace it with something smaller?

Then don't be surprised when Jay (or someone else) asks you to delete your signature (we're not allowed to have animated ones anymore). ;-)

What? Okay I’ll remove personally I think it’s a bit &*(^)*^*()__ Yeah. So things have changed in two years.

Wow, that thread was like having vice attached to your nuts, and having the force applied at the same time!

The force of the vice, or The ForceTM?
