I'm currently just recording in my bedroom, but I was just wondering about acoustics, as my knowledge on this subject is almost non-existant. I was reading an SOS article about some guy's home studio. Here's an extract:
Another important design consideration was the acoustic response of the room. Once again, Russ was methodical in his planning. "I read in a Paul White article that a concave or arched space is the worst acoustic space you can get. I realised that was true when I bought the Genelecs, which are supposed to have really good stereo imaging. Even with them I didn't have a stereo image, because the sound bounced off everything. I could pan, but there'd be no noticeable difference at all!
"So I started experimenting with the lagging that you see on the walls. There's an upholsterers nearby that supplies a lot of material to hotels and hospitals, and they have a big odds-and-ends box. I bought masses of the stuff; 12 square yards for £10. I attached wooden batons to the ceiling and used a big staple gun to fix the lagging to them.
"The lagging worked, although the room has a bass hump at about 80Hz. Realising that, I bought a graphic EQ so I could filter that hump out. I've set the EQ so it dips at about 80Hz and comes back up at about 40Hz, although the monitors roll off about there anyway. Now the room response is quite flat, and considering its size and location it's not a bad recording space."
------------
I have a few questions from this:
1) How do you know when you've got lagging on the wall?
2) How do you know if you've got a bass hump?
Basically, how do I know what my room is doing to my recordings? How do I know if it has a flat response. I've heard people sayong things like, "I've got a bit of a bass hump patch to the left of my back wall" - how do they know this?
As you can see, I know nothing on this subject!
Thanks!
