Topic: Roll Off

[RobertNC]

My only hard and fast rule is don't let dogmatic thinking get in the way of pulling good tapes.

Once I got past this "rule" of you can always take away but you can't add back, I found that for a lot of the types of music I record in the kind of rooms I record in, running my on board 40Hz rolloff really sounds nice.  I'm no sound engineer and don't really understand the differences, but to my ears the results often sound "cleaner" than doing the same amount of roll off in post.

I don't know, maybe I'm just being a pussy.

47 hz might have been the spot
you lost 7 superclean hz of phatt

re create it in post is playing in the dirt.
once you get it clean you always want it clean
roll off is best done like this

Yo g,

I'm not up on  this new math, but I think you meant that super phatt 7 hZ  above 33 maybe?

Anyway I don't drive a tuner car with ground effects and a row of subwoofers in the trunk, and to me the lower range is more pressure than sound.  I don't try to rumble the hood so I like the rolloff myself.

see you got it

It's all about running gear and figuring out what you like. 

If you really wanna know if the water's just fine, stick your finger in and make up your own mind.

I always seem to find the lower register instruments on the right.  Maybe that's an East/West coast deal?  Cello & viola on the right yesterday afternoon, violins on the left. Miami Bch, ocean on the right side facing North. 

Hi-pass on one side? Never considered that before. Interesting.

should you roll off before or after adding gain?

If you remove some of the lower frequiences, you are also going to reduce the average db level of the entire wave form. Therefore, it would probably be in your best interest to remove the frequencies first, and amplify it with some digital gain as a final step.

it was so hidden
but i got it

well done on the cloak

hey robert,

i recall you talking about using the high pass filter on the 7xx series in the past. what setting do you use? you mentioned 40Hz, but what slope do you use? (12,18, or 24 dB/oct)

the reason i ask is b/c i have an upcoming show with a band/venue combo i always roll-off in post. i'm thinking about giving the 722's filter a shot. in the past i've set my filter in post to 70Hz @ -3dB/oct. I'm trying to figure out which setting would be best in this situation.
