Marty. No dubstep goes to 10 hz. In fact in over 5k analyzed tracks, I've yet to see one touch below 20hz. a very small minority touch below 30hz, a majority are above 40hz only.

things in the mid/high 20s are considered, the "lowest" tracks out there. Of course theres stuff like "bass I love you", and theres a whole thread of this one guy on here who produced tracks with content in the teens, but none of those tracks ever get played anywhere but on the insane HT setups seen here.

Heres some "low" tracks for reference

Asteroids by Vivek (31hz bassline)

http://www.youtube.com/watch?v=RCIyvKc7W-4

Puppets by Truth (28 hz bassline at the begginning of the bass drop)

http://www.youtube.com/watch?v=tGDtfTZjZ7w

Hunter by Kaiju (35hz bassline)

http://www.youtube.com/watch?v=UnQY3swM4tA

Face Melt by Tunnidge (32 hz bassline)

http://www.youtube.com/watch?v=vJCmCh3zMNE

I'll post some more if you want

Can you find out how low a track goes? Because I've been wanting to know the lowest Hz in "Worldwide Choppers" by Techn9ne. There's a spot in Busta Rhymes verse about 4 minutes in that shakes pictures off walls

there are a variety of ways.

the coolest tool is spectrumlab. it is complicated to set up, but if you search around you will find a guide or two with exact pictures of which boxes to check etc.

then you just play a track and it will display visually the content by frequency. very cool.

Listen. It's All Good.

here is the track at the time that you mention:

the purple bits are the monster bass hits that you are hearing/feeling. they are around 32hz and then some around 42hz. 32hz is pretty low for music, but it is not 20hz and definitely not 10hz. most folks get too caught up in the low numbers, when what they really need is SUPER LOUD hits from about 28hz up.


Listen. It's All Good.

Can someone run a spectral analysis on the Beetlejuice dubstep song? It's by Figure. I'm curious to see how low the drop goes in that song, I was guessing some of it touches 20hz.

those "drops" go down to 28-29hz, but then there are a couple random boinks at 12hz. maybe that is to just ensure that everybody with a ported sub is either running a high pass filter or loses their drivers. :-)

lol thats actually pretty funny. where are the 12hz parts? any chance they are the product of sloppy sampling?

Nope just checked it out. appears to be intentional I guess lol.

I thought I noticed some sub 20hz stuff. Right at the end before it starts the drop over and lydia says beetlejuice beetlejuice beetlejuice- It's probably the only dubstep song I could think of that I thought had sub 20hz content (as little as it is)

Hello, I wandered when Dubstep would get a mention, lol.

 

What about shed loads of SPL at 33hz? I only ask because its the resonant frequency of a certain part of the female anatomy......

 

It is valentine's day afterall ;-)

What was the test setup for that?

not sure if there is anything to it, but it was mentioned a few times on various sites.

"Don't touch that dial. The idea that 33 Hz is the optimal resonance to get a woman off originated with an experiment performed in 1992 by car-audio consultant Todd Ramsey. While on spring break in Daytona Beach, Ramsey and his buddies spent three days asking women to sit in the front seat of a Honda Accord. The crew then swept the frequencies from high to low on an 18-inch subwoofer, powered by a 1,000-watt amp, in the trunk. The women gave the thumbs-up when the vibrations felt best. Once Ramsey had crunched the numbers for about 100 volunteers, including making adjustments for their self-reported weights, he calculated that the optimal resonance for a woman of 115 to 125 pounds is 33Hz. Not so coincidentally, he says, that’s about the same resonance as an idling Harley or a spinning washing machine."

Listen. It's All Good.

Pretty funny LT!biggrin.gif Yep...The fix is in to get those dual-resonance systems to perform complete self-immolation!

Groove Radio went online in '95 but the Shoutcast wiki says it was created in '99. On the other hand, I started listening to Swedish Egil back when he was on KROQ in LA...

Just curious...
