Firstly the angled channel should be OK - hey it works horizontally 
As far as the plywood verses sheetrock goes, I'd tend to go for both but thinner versions of each. i.e. sheetrock it in 1/2" then overlay it with 1/4" ply for the finish.
BTW Plywood is used extensively throughout studios in place of sheetrock. It has more mass, has a variety of layers for the sound to travel through (something sound doesn't like to do) and provides rigidity to the whole frame especially if it's glued and screwed. I can't see how someone would recommend sheetrock over ply unless they were concerned with the extra cost of ply

Ok, I was DEAD wrong. I guess that's why I'm not designing studios
It's kinda funny, until I started talking on here with everyone about building stuff, I had no concept of sizes with the metric system. I'm starting to get it now, (after using a converter all the time)
Maybe everyone in the U.S. just needs to build a studio and then we'll switch to metric in no time.

yes please
I grew up on imperial like you and had to switch. Believe me it is much easier AND more accurate.

I'll just put some more up incase anyone wants to see....
This is the outside..it's essentially a "shed" because it's not built into the ground it's just ontop of it. We hired a contractor to build the external structure and other than not into the ground it's just built like a house (i guess)

Exec,
Looking good my friend.
One thing puzzling me is why you didn't just mount the construction on floats, sit it in the pool and have terrific isolation from ground/floor vibrations. Just imagine the guys wanting to book time in "The Studio Afloat"

good idea! Maybe it's not too late. I'll get a crane and have it mooved.

Well obvoiusly you are not the one in the red shirt.......else you wouldn't have asked all the questions just joking
looking great - that's resilient channels !!!!......... in fact the second pic shows it even better but we are distracted by Butch Cassidy and the Sundance Kid armed with their weapons

ok well we figured out the floor and put it all together yesterday...It came together VERY well.....easy to do, seems like it's just the right amount of "spring" in it. I didn't buy the pads from soundproofing.org, I found a place by me w/ 3/4" neoprene (60 duronmeter) for about $60 to make pads for the whole floor, 14x18...
Anyway we did the inner frame today. You can see the frame and a bit of the floor attached. It's too bad I didn't think to take pictures of the floor before the osb plywood was on it, because I know seeing it before we did ours would have helped me. We have one picture on reg film, not developed yet....i'll post it when I get it.

A few Questions, Executivos:
1. What type of insulation do you have under the resilient channeling?
2. What goes on the inner wall?
3. When completed, how big will your room be?
Looking good. Glad to hear the floor went well.

we have regular fiberglass insulation under the resilient channeling. John Sayers said it's better to use rock wool, (at least on the outer layer) but when we're done using the room as a practice space down the road a few years, my singer's parents (ones that own the space) are going to tear out the inner wall and just keep the outwall probably turning it into a game room or something, so we tried to use regular stuff. Rock wool, I've found, is rare and expensive here, about .35 a square foot, and I found fiberglass for .18 a square foot. Apparently in australia and england it's more common and cheaper.
What do you mean by what goes on the inner wall...(be specific)
It's a 2x4 frame with fiberglass in that cavity as well. There's 5/8 sheet rock on the inside (room side) of that frame, but not on the outside (air cavity). This is very different from John's design, and in an ideal situation, I would have followed it, but it just didn't work out that way.
The room was built as a 14x18 room, and we were going to leave about a 2-3 inch airspace, but when we started measuring, we choose to leave a bigger gap of about 7-8 inches, because that made the inner room 12x16.....much easier to work with as plywood and drywall panels are 4x8 and fit evenly. The extra inches are valuble real estate, but oh well. 12x16 is big enough to practice in.
I hope this helps. Next tough thing to tackle is building our ventilation ducts without leaking sound.

Thanks Executivos. Man! it really helps to not only see what you're doing but to hear why, too. I'll keep that in mind with my project.
That is a bummer about Rock wool - Since we both live in the same state!!
Does anyone know of another product that would substitute well? I figure one layer of rockwool for my studio at those prices will cost well over $500. Since I'm building a recording studio and not a pratice room, I feel I'd have to get it.
Executivos - was that a local store price? Perhaps it could be ordered from elsewhere for less.

I called EVERYWHERE, looked online, looked in the phone book, the only way I was able to find someone who had it was to contact roxul by email. they gave me a number to call of a distributor....the distributor gave me the number of the company they distribute to in my area.
If it's too expensive then you might just go with insulation. From what I've read it's not THAT much of a difference.

Wow, I should have guessed that you would do your homework!
I'll probably invest in some rockwool, at least for the floor. BTW, Who is the local distributor in CA?

where in so cal do you live? I'm in the ontario/upland/rancho area and it was in chino. I'm sure there's more than a few you can find, but most likely their prices will all be pretty close.
You can save some money if you get 1 1/2 inch thick. (I was looking at 3 inch)

I live down near Lake Elsinore. maybe an hour and a little more south of you.
Good to know that there are cheaper rockwool options. I wonder what the difference in terms of sound absorption there is between those two and the fiberglass?
Why did you go fiberglass as opposed to the thinner rockwool? because of the eventuality that the room will be reconverted at a future date?
I'm going to have to sit down and budget all this stuff, see what my costs will be

well there were numerous reasons why I went with fiberglass over rockwool, the main one being that john said it wasn't too much of a difference acoustically, he actually said the outer wall should be rock wool, the inner wall should be fiberglass because it's acoustic properties were more favorable. In the end, it was cheaper and easier to use fiberglass.
here was john's reply to me after I asked if I should use rock wool instead of fiber glass...(btw in us it's called mineral wool not rock wool)
posted by john sayers:
"....In OZ it's heaps cheaper, so I presume it is the same for you.
Yes - use it instead of fibreglass but you have to go to 4" I reckon. I've done studios in it and the carpenters prefer it to glass fibres. Dacron is their first choice so I use that if the budget will allow for it as its over twice the price. 2" Rigid is the best on the wall I think. It's absorption curves are the best whereas rockwool is the best in the cavities. Where you have to make the frame first, plaster it and then stand it up dacron is the easiest cos it comes in rolls but you can get rockwool in sheets.
cheers
