Ok... I'll continue on topic... with best example, Blackbird Studio C, "100% diffusion".

Dawn Langstroth, George Massenburg, recorded and mixed (live) in Blackbird Studio C:





Enjoy!

The piece goes somewhere () and that someone's arm gets cut off to replace it

No way! heh
It must be the same piece of MDF....
With someone's arm instead of exact piece of MDF, whole room will sounds different!

is MDF strong enough (dense?) to keep a 3ft piece from sagging over time? or any challenges regarding gravity that had to be taken into account with the deep wells? that's a question i always had.

I believe MDF sticks sagging may be neglected if humidity is kept low...

Hmm... I don't see/know any connection between deep wells performance and gravity...

in case anyone missed it, here's a camcorder in that studio, with some guys talking:

The Vagabond Soles @ Blackbird Studio‬‏

"Smells like a ****ing toothpick factory"... hmmm, I wonder if that's distracting at all?

I've never heard of Dawn Langstroth. Stranded is a great song and nice to see the whole band playing at Blackbird. Thanks for posting!

That's a strange mix. The instruments sound pretty good but the voice... sounds like she's singing in a anechoic chamber (and unfortunately makes me feel like I'm in there with her), and it doesn't fit at all with the rest.

that 2nd sentence was still related to the 'sagging' topic in the first sentence - not meant to be presented as a separate issue. disregard

Despite the camcorder quality and ****ty youtube compression, you might be able to tell the difference in audio response as the guy walks between the two studios and other rooms.

It would be sweet to have a walkthrough like this for different studios and environments (like an ambionic chamber), done with better equipment in a consistent manner, to get people to hear the differences.

Ah, sorry, if sticks aren't totaly sagged/melted like wax, they will still work very well... some sagging doesn't matter.

I found another record from RES Media recording room, this time is male vocal

File is very large, ~20MB... 192kHz 24bit (I play it with Foobar2000)

The other 138,645 block heights have to be adjusted to compensate.....heh

actually...

the prime number which determined the primitive root diffusor calculation was suggested by Peter DAntonio (my collaborator in the project) was is 138,647, yielding co-primes of 181 & 766. this linear series was folded into 2D by the Chinese Remainder Theorem. there is roughly 47 tons on the walls after milling on a Cosmac horizontal mill, which ran for about 3 months cutting 1532 pieces of 1" MDF. we had thought that "sagging" might be a problem, and worked out a system of installing 1/4" dowels at strategic spots in the array to support it should this be the case - it hasn't been a problem, though.



note in this ETC that the decay is approximately 0.3 seconds, but more importantly, the direct to ambient ratio is in excess of 30dB, which is also the reverberation spec for an anechoic chamber.

the room is hardly anechoic, though. just listening to music in there is extraordinary; ensemble musicians report that it's easier to play live in the room because it's easier to hear in the room.

those that appreciate it use it to it's utmost. the "sound" is more or less like an "acoustic white-out", and the decay is extraordinarily linear with higher frequencies (the Schroeder curves are remarkably linear) having more decay than any other room i've ever experienced. i made the best record i ever made in my life in there (from which that video clip came). unfortunately, Nashville's short-sighted and inept "music" industry will not tolerate innovation of any kind, and i'm told that the room now has heavy curtains hung in front of the diffusors.

i now live in Montreal, by the way.

If that room is long I would doubt it myself. Who really knows though what other things they might have in that room with regard to low end control. I for one hate rooms that are shaped like that as it seems to have a really bad (I like to call) tunnel effect.

What you see for instance at the bottom of the sidewalls are Helmholtz resonators.

Some pics below of another room with much diffusion.

1. you'd have to hear the room. the quality of it's ambience is not in your's or anyone else's experience.

2. the shape of the room is rectangular. like many of the great concert halls. sorry that you hate rooms that are shaped like that - it's one of the most dependable shapes we know of. don't know that any of us have heard a "really bad tunnel effect".

3. i'm never heard of a "tunnel effect".

btw, BB-C is very close of cube root of 2 differences between H, W, & L.

It is rectangular? If so then I take back what I said. From looking at the pictures it looks like slatted side walls and long. BTW if that is your room I am impressed, looks really nice.
BTW I should have not used the word "hate".

I think the lens used to produce the photo (wide field of view I think) exaggerated the apparent length of the room.
