Dynamic response and Bottom End

by **DwaneHollands** » Mon Jan 24, 2011 3:21 pm

Hi Guys,

Would be it be fair to say that by cutting the bottom end out of a source, that you're reducing the dynamic response? It would seem to me that dynamic response is more important for 'bottom heavy' material, is that correct?

I've just notice that if I really do some cutting in the bass, the signal almost appears compressed (with no artifacts that is) and more manageable.

(this is the place to ask stupid questions right ; )

dynamic response??

what do u mean by that?

i assume u mean, "cutting the bass gets rid of random shit that shouldnt be in the signal"...

i guess that statement is source dependant...if something has alot of bass, cutting it would be a bad idea..

i dont think low end cuts make a signal sound compressed...it may get rid of some bass material which could make ur compressor pump tho...

I suppose I mean perceived loudness or perhaps energy. When you're compressing, you're trying to reduce the amount of energy in the signal,right? So that it becomes more manageable and less dynamic. It just seems that most of that energy is in the bottom end. I've just noticed when doing a dramatic cut in the bottom end, it appears to reduce the dynamics, kind of like squashing it with comp - without eq.

Just seems to me there might be two approaches to making a full range signal more manageable...

You've answered your own question, since most of the energy in a musical signal is in the bottom end (compare the power of a set of live music subs to the power of the tweeters) then cutting the bottom end reduces the energy available in the signal.

Yeah I suppose I have, just wanted to see if I was on the right track.

Thanks guys!

Refer back to Fletcher /Munson curve.

Sup Heath! Long time!

From looking at the fletcher munson curve, it appears that it requires more bottom end in order to match the perceived loudness of a 1khz. So it seems like midrange has more energy. Or it's more efficient - in regards to how we perceive it.

So I dunno...haha.
