Just to be sure, this is stuff right?

It's way better than the pyramid ones. I saw exactly this in many studios.
The question is: where do you want to use them? editing suite, control room, speaker booth?
Wood panels sound better, like wood diffusers.
 
Really?!?!?

I need some reverb cancellation on the ceiling of my walk in closet/sound booth and some small openings between the shelves... I got the bulk of it taken care of with cotton sound blankets and hooks

But if this stuff helps I'd get a ton of it and put it on my loft/editing loft
 
I think that they could do the job.
But acoustics is a science and for our sound booth we hired an engineer who designed the inner of the booth with tons of wood lists, bass traps and other tricks. He did it with a computer, he costed 300$. This is our favorite booth, it sounds very good.
In other words, do not improvise with acoustics. But if you are looking for a pro looking ambient, they are wonderful.

I am doing it with trial and error... so far it sounds ok... so I guess next up is getting a few of these unless someone has a better idea...
 
Experiment a little before spending a lot of money. Maybe you already have. A good series of detailed articles are here:

You said two things that struck me. Bookshelves often make excellent diffusers, so usually you don't need to treat small spaces between them, or small spaces between many hard surfaces. In fact some studio diffusers are actually just hard boards spaced closely. Another thing I've found is that you sometimes only need to treat one side of two parallel surfaces. So if the floor is carpeted, you often don't need to treat the ceiling. Hopefully those things can work for you and save you some money.
 
Absorbers and diffusers are different things. I don't know how much actual absorption the foam will provide. In most cases you don't want a LOT of absorption but you do want a lot of diffusion. Book cases and those square panels that have different hight sections are diffusers. Foam absorbs a bit and diffuses a bit, foam on top of an absorber sucks sound like a vacuum cleaner. In most editing rooms you don't want it "dead" but you don't want a lot of bounce either so book cases and diffusers work well with some soft areas to absorb some sound. Recording booths are usually pretty dead, though personally I like ones where two sides are very dead and the others are less so. You can move around and get pretty live to very dead. In our Foley stage two and 1/2 walls have blanketing covered in foam, get close and you loose thoughts, the rest is hard and flat (glass window glass sliding sound door). The ceiling is curved and un treated and the floor is a slab but often has rugs covering most of it. People love working in there. If you move close to the all foam corner it's VERY dead, if your over by the hard corner it's very live. But nowhere do you get any real bounce echo because there are no parallel surfaces.
 
cool.... thanks for those posts guys... I have been reading the Audio Postproduction for Digital Video by Jay Rose and you guys added to what he described there... I went downstairs and reconfigured my booth I now have the sides (clothing) covered with cotton blankets and then I doubled up the blanket covering the wood door which is now behind the talent... My floor is carpeted but I will also throw a heavy old towel or two on it cause my ceiling is bare popcorn... I was wondering it I should go with a few of those foam squares for the ceiling...

the mic is a Hypercardioid Oktava MK-012 and right now I put it in a corner as Jay Rose recommended but I am curious to see what u guys thing of it since the wall behing it is bare... heheh well kindof... there are still some purses hanging there heheheh I can take those out easily but I was wondering it in fact they might help? lol... who knows hehehe

I am still to try recording but will do so and post back my un-trained impressions of different mic placement.... I was hoping you guys could give me some thoughts before I go and do what my ears tell me to

I have a cheap snake I built to I can let the talent know when I am ready to go to the next clip and tell him to switch to Tape Return on the MixPre which works ok coming out of the Tascam US-122 and all along I can hear him through the mic... I have Sony MDR-7506'ers for mah ears and Seinhnheiser HD280 pro 64ohms for talent...

Not gorgeous but the booth does look much better in person :)
 
I am not happy with it at all really... I know this isn't supposed to be a great sounding booth but I was hoping for more... please help me make it better...
 
Here is a sound clip... 3.5MB

Mic aimed at mouth three distances

and this is what I need to pull off... my character talks to Michelle's character from the table... he later walks over... they walk down a little paved path but all else is grass and trees... all of that I actually recorded in a quiet park with no reverb so I just need to record the dialogue from the table and about where Michelle is

Please help, will some of those foam squares on the ceiling do the trick? Is there any way to remove reverb in post?
