Department of Homeland Mathematics

Apparently the Department of Homeland Mathematics held a meeting that I missed recently, where they decided that 11.5+11.5+11.5+10.5=35.6.

This week, my paycheck was significantly less than it normally is. So I came into work on my day off to investigate, and discovered that the program that keeps track of time (our punch in/punch out timecard system) does math differently than the rest of the universe. All the hours I’d worked were there, it’s just that they totalled it incorrectly.

Ah well. Everyone at work was baffled. Supposedly on Monday someone in payroll will cut me a check for the remainder. Somehow I couldn’t help Tom Ridge grinning his inane grin at me and telling me this is all for my protection…

audiogeek verbal diarrhea

Over the past many moons, I’ve been frequenting several audio and acoustics forums (fora?) to try to learn to educate myself about good acoustics principles. And, I’ve learned a tremendous amount from reading these forums.

So I decided to write up my recent experiences, to try to give back in some small way. Maybe someone else is in a similar situation and would be helped by my experience.

There is an overall writeup of what I did, and in a different place I posted detailed instructions on the gobos, including a diagram.

Do they make audiogeek pepto bismol?

Last night I got the studio rewired (mostly — microphones and speakers work, I still have a bit more to do for everyone’s headphones, etc before we record). I’m thrilled that everything is working just as it was; nothing went *poof* and the resolder job I had to do works perfectly. w00t!

So last night, after a couple of minor false starts and everything was rewired (thanks to Matt for climbing behind the desk to plug in the preamps … several times as it turned out, heh), I arranged the bass traps and the gobos around the desk, and fired up some music.

WOW! What a sound. SO much more focused than it was before. The “sweet spot” — or, the listener’s position at the apex of the equilateral triangle with the speakers — sounds fantastic. The bass is MUCH tighter, less boomy, I can actually hear what’s going on in the low end. The imaging is much more precise, even with my low-end monitors. If it sounds this good with those, then I can’t wait to hook up my Dynaudio speakers from home in that room. Regardless, I have plenty of listening to do to familiarize myself with how this room sounds, but as I told Matt last night, we can DEFINITELY mix an album in this space now. Mission accomplished!

After we listened for a while, we moved the gobos out of the way and got out the microphones. We spent some time arranging them into the theoretically correct place as a starting point, put the bass traps and gobos back into place, fired up some headphones, and while Brent was playing I moved mics around one at a time.

I actually recorded a few minutes of drums…. wow! More low end, a tighter sound than ever. Much of this is, of course, due to the new drum heads, but several links in that particular chain have been upgraded lately. I also added another mic to the drums, so now I’m recording 6 channels of drums. So again, Mission Accomplished!

In our recent demos, the only part that sounded “right” in terms of final production was the bass. Now, I’m happy to say, the drums have a similar “finished” sound that should fit nicely into the mix. I can’t wait to record my acoustic guitars in this space now, not to mention vocals, not to mention mixing, not to mention mastering, not to mention selling thousands of CDs. :-)

Countdown to our basic tracks recording session: 12 days. Lots to do before then, cleaning, “vibe” detail (making the space comfortable and as aesthetically pleasing as possible, given the proliferation of “construction” scents in there at the moment…bleah), not to mention cleaning up preproduction for all our songs.

Busy, busy, busy.

So the studio build continues. Today we reinforced and expanded the mixing desk, adding a layer of MDF to the top shelf, several more braces, and an extra leg in the back where all the weight is. The top shelf, where the speakers sit, is now angled so that the speakers point inwards at a 60 degree angle, so that it is possible for the listener to sit in a sweet spot where the listener’s ears and the 2 speakers form an equilateral triangle.

This is ideal, in terms of listening. Plus, this sweet spot is 38% back from the front wall, which is a very good spot. However, I think the triangle is a bit too big, as the edge of the desk is only about 6″ out from the wall. I definitely want to get more cotton behind the desk.

After we finished building and installing the desk, I arranged everything out on the new shelf and begin the tedious process of rewiring the studio. The snakes are run, and I resoldered the broken RCA cable for the S/PDIF input on the sound card.

Can you feel the audiogeek love?

I thought that you could….

Anyway, still haven’t heard anything yet there. I’m dying to listen to audio through the speakers with the acoustic treatments up. Tomorrow night, I should be at this stage. Not looking promising in terms of getting drum sounds yet, may have to wait until next week….

still stirring

I’m feeling a bit better today. That’s good.

I picked up my PodXT Live today. I also ordered a Variax 300 in black. Very cool.

My attentive readers will recall that we ordered acoustic cotton recently for all the studio sound treatments. This material is reasonably new on the scene compared to rockwool and fiberglass, and one of its main benefits is that it is nowhere near as toxic as glass or mineral fibers. It’s also cheaper, it turns out, as I discovered when we recently ordered some online.

Little did I know how much cheaper.

I discovered today that there is a local, green friendly business that sells this stuff…. for less than HALF of what we just paid for it online. Doh!

Ah well. Live and learn. We haven’t finished our treatments yet (we’re only on phase one) and we’ll need more. It’s good to know that there is a local place to get it a bit at a time.

the (lack of) sound of sweet exhaustion

I’m completely exhausted. I’ve been flirting with the flu all week, achy, headachy, and slightly congested. But, I’ve been pushing myself harder than I’m accustomed to this week, and we got lots accomplished on the studio front.

Phase one of the studio acoustic treatments are drawing to a close. All 6 gobos are finished, all 6 bass traps (or more accurately, broadband sound absorbers) are finished, the fiberglass is up in the first treatment spots, covered by blankets, and the entire ceiling is covered in fabric. Plus, the 2 bass traps that hang across the wall/ceiling corners are installed.

All that’s left is cleaning, rearranging, and rewiring the studio as we pretty much had to unplug EVERYTHING and move it during this process. So there is still plenty of work to be done. I also have to resolder one connector that broke off during the process. Lots of nagging details.

Another thing is that I’m thinking of modifying the desk, making it such that the speakers can be properly angled (the idea is to have the the shelf holding the 2 speakers to be at a 60degree angle so that they will make an equilateral triangle with the listeners head at the listening position). This week I hope to get to that, since there is already some reinforcing repair work that needs to be done to the desk as it’s sagging a bit in the middle.

However, last night was The Big Test(tm). We actually played some music, for the first time in several weeks. That was very cool. The effects of the new acoustic treatments are obvious. It’s one thing to absorb a lot of theory, with all the studying I’ve done on studio acoustics, yet quite another to build something that actually works. Last night was our first clearly audible confirmation as to just how well these treatments work in our studio.

Brent had put new drum heads on the entire kit, all the way around. So the first thing is that the drum kit sounds fantastic. MUCH better than it did with those way-too-many-years-old heads that wouldn’t get in (much less stay in) tune. The heads are really nice Evans heads; basically Brent copied the heads used by one of his favorite drummers (John Dolmayan from System of a Down). This is an older, vintage-ish Gretsch kit, and man it sounds good.

The sound of these drums in the room with the panels arranged around it is hard to describe. The best way I can think of is to say the sound is much more focused, since there aren’t any (or vastly fewer) reflections bouncing of the walls, floor, and ceiling. The sound actually seems to be coming from the drum, as opposed to the more diffuse sound of the drum-in-a-reflective-box thing. Again, it’s hard to describe but it is clearly audible. I had warned Brent that the difference in sound would be subtle, especially to an untrained ear, but his reaction was quite exuberant: “You said this would be subtle, this is a HUGE difference!” Even our friendly neighborhood curmudgeon-in-training bass player appreciated the difference, “this is much more like a real studio.”

So yes, I’m quite thrilled to see theory put so effectively into practice. In short, the designs work! And as always, Matt and I worked very well together in constructing them. The gobos aren’t necessarily pretty, but they are MASSIVE and heavy and effective. Cleanup work, and wrapping up some loose ends, is all that remains for phase one. And I hereby declare phase one a massive success! w00t!

Phase two will be to complete the framework construction of the room by adding more fiberglass and sheetrock, along with 2 reinforced doors. This will much more effectively isolate the room, so that when we record basic tracks, we can put Matt on the other side of the door to get his voice out of the drum mics (and the drums out of his vocal mic!).

Once the room is “finished,” phase three will be to add more room acoustic treatments, either more of what we already have (bass traps and gobos) or something that is more customized to this room (which means they’d be harder to move down the road if we ever need to). But, the wheels are turning here, I have some very interesting ideas to acoustically optimize the space we have.

And the best news is last: Freakwitch has officially scheduled April 13,14,15 as the 3-day-solid stretch of recording our first album! I hope to get basic tracks done on those days (meaning: drums and bass recorded for every song). Then we can begin overdubs with guitar (including electric as I’ll have my new rig by then) and vocals.

Ever onward!

time to go wash…

…the fiberglass out of my hair. Bleah. What an unpleasant task. But I’m happy to say that about a third of the studio ceiling is now fiberglassed and covered with blankets. Eventually we will also cover what’s there with some of our fabric.

It really makes a BIG difference in sound. Once we got it up, we’d stand under the fiberglass and make a loud, sustained sound and then walk out under the fiberglass. As soon as we got out from under the fiberglass, we’d start laughing because the sound changes so much! This is cool. It should help us tremendously.

Tomorrow night we get to build the rest of the gobos, then on Tuesday I have to rewire the studio, as we had to move everything out of the way. I also have to resolder one connector that broke while we were trying to unplug the cable that had become corroded. Work, work, work….

everywhere I look, seeds are germinating

and it’s quite a good feeling. Spring is coming.

All the bass traps are built at this point for the studio. We’ve also built one of the gobos, as a proof-of-concept/prototype thingy. It seems to work as planned. Only 5 more to build. We also picked up enough fiberglass to stuff the ceiling joists, giving an absorptive cloud, above the drum kit and the mix position (about 2/5 of the room). Things are moving!

I’ve been in a MUCH better headspace lately, too. Now I’m in the mode where I’m enjoying my emotional clear skies, and watching people around me weather their storms. All is well.
