Music Studio in my Studio apartment!

This is your new home if you already have a studio, but it isn't working out for you acoustically, and you need to fix it...

Music Studio in my Studio apartment!

Postby recaro19 » Wed, 2019-Oct-09, 18:08

Hey everyone,

New to the forum and very excited to be here as I embark on this journey in professional music production. A little bit about me. I'm a DJ and Producer out of Toronto, ON. Been putting my career on hold for quite some time and up until a few months ago, I recently moved into a much better space that will (hopefully) allow me to get creative again.

The purpose of my studio is mainly for working in the box with some outboard pieces of gear. It will be primarily used for production and mixing. I do plan on recording but nothing major. Some hand instruments and such just to add some unique sounds textures to the genre I'm making. I predominately produce techno and progressive styles of electronic music.

Here is the current gear I have:

- Komplete Audio 6 (what was used for REW measurements)
- RME Fireface UFX
- Dangerous D-Box
- Neuman KH120's
- Sonarworks Measurement microphone

I also have a second set of monitors which are KRK Rokit 8 RPG 2 and a KRK 10s subwoofer. I am not planning on setting these up just yet as I want to make sure I have position and measuring of the KH120's first since they will be my main near field monitors. I'm also not setting up the RME and D-box at this time so I'm using the Komplete Audio 6 for now as I'm not sure how to take measurements with the RME and D-Box set up. I'm assuming it won't matter which soundcard I take my measurements in but any insight on this would be greatly appreciated.

From what I've learned so far, I will most likely require two large Superchunk bass traps in the front two corners and bass trap panels at 6" thick all around using Roxul Safe n Sound. I'm planning on cutting some wood at 24"x24" to cut into triangles which will give me two pieces with an approximate 34" face for both the top and bottom of the Superchunk. This was what was recommended by Mike at GIK after speaking with him about DIY options. I'm going to be making them 72" high since I need to leave about 24" from the floor to make room for two outlets on either side. Of course, I'm here to learn and since I haven't started building any sort of traps I'm still open to recommendations best for my room.

In terms of REW measurements, I had some trouble getting initial measurements when I first started out. Stuart knows of my multiple attempts but after carefully revisiting his instructions, I think I've figured things out. Here is the latest measurement file:

If things are still off please do let me know and I will circle back and re-measure. Please note that I am a total beginner when it comes to measuring a room and reading these graphs. I have limited knowledge in terms of what each graph is showing me, but I do have a slight understand from my knowledge in the pro audio world. What I have trouble with is understanding how to identify problems based on the information the graphs are giving me and how to interpret them to make the correct treatment decisions.

Here are the dimensions of my room as well as a 3D layout:

These are photos of when I first moved in to give you a better idea for the space:

And here is the current set up of my room. I've built a monitor shelf to allow for my sweet spot to be a bit smaller and got rid of the TV on the keyboard stand so my desk can be pushed right up against the wall. I already noticed a better sound from the below set up compared to the above.

I am very excited to be here and already have noticed some great improvements from my new setup. Just looking to take it to the next level and really open up my stereo imaging and sound quality. I look forward to working with each of you and if there is something I missed in terms of information, please let me know. I will be watching this thread actively while at work as I'm hoping to get to work on this project soon.

Best

Hi there, and Welcome! :thu: :) So glad you made it over here, to the new forum.

- Neuman KH120's
I think I said this to you before, elsewhere, but I'll say it again: Those are nice! They should work well in that room.

I'm assuming it won't matter which soundcard I take my measurements in but any insight on this would be greatly appreciated
There's probably very, very little difference at all. Most audio interfaces these days are pretty darn good, with only very minor differences. If you really wanted to, you could do calibration and testing with both of them, to see if you can find any difference, but I'm betting that they will be the same.

From what I've learned so far, I will most likely require two large Superchunk bass traps in the front two corners and bass trap panels at 6" thick all around using Roxul Safe n Sound.
Something like that, yes. I would also consider doing another superchunk horizontally in the wall/ceiling corner directly behind you (above the bed), and something very think on the rest of that wall.

You have a strange shaped room, which isn't symmetrical behind you. Normally, that's not to much of a problem, but in your case, you have a large reflective surface back there: the wall and door to the bathroom. That's going to need some serious attention too.

I'm planning on cutting some wood at 24"x24" to cut into triangles which will give me two pieces with an approximate 34" face for both the top and bottom of the Superchunk.
There's not really any need to build "shelving" for your superchunks; you can just cut out the triangles of OC703 directly and stack them on top of each other, like this:

Just a few photos of how they are done, typically. You'll probably want to build a light wooden frame and stretch some attractive fabric over it, to hide those ugly monsters behind.

I'm going to be making them 72" high since I need to leave about 24" from the floor to make room for two outlets on either side.
To be fully effective, superchunks should run from floor to ceiling. If that would cover over an outlet, then consider extending the outlet with a surface-mount raceway, that can cover over the existing outlet and be used to extend the wiring to a more convenient place. Legrand makes good systems for that.

Then you would just cut out a some parts of the OC703 to fit around that.

In terms of REW measurements, I had some trouble getting initial measurements when I first started out. Stuart knows of my multiple attempts
:thu: I remember! :)

but after carefully revisiting his instructions, I think I've figured things out. Here is the latest measurement file:
Yes! It looks like you got it right! The data is valid, and in fact your results are not too bad at all. One surprising thing that caught my attention, is just how closely matched your left and right channels are: there's not a lot of difference between them at all, which is a very good thing: It means you have your room set up symmetrically, with your speakers placed and aligned accurately. And it also means you have good speakers, of course... :)

Your overall frequency response is reasonably good, with the expected modal stuff going on, and your decay times are all fairly close to each other, across the spectrum.... just too high. Around 600ms right now, and you'll probably want to get that down to around 250ms or so.

The good response is partly due to having a nice sized room, in addition to the other things I mentioned.

I would say that your room should be able to turn out rather well, if you treat it suitably.

If things are still off please do let me know and I will circle back and re-measure. Please note that I am a total beginner when it comes to measuring a room and reading these graphs.
You are doing fine! You have it all figured out now: your measurements are good, the data is valid, and your room is looking very promising.

I have limited knowledge in terms of what each graph is showing me, but I do have a slight understand from my knowledge in the pro audio world. What I have trouble with is understanding how to identify problems based on the information the graphs are giving me and how to interpret them to make the correct treatment decisions.
I'll try to respond to that a little better tomorrow, with some examples from your own data, but interpreting REW graphs is both easy and not so easy! :) Easy to get an overall idea of what's going on, with a bit of insight about what they are really showing, but also "not so easy", in the sense that there's a lot more stuff hidden in there, if you just know what to look for...

And here is the current set up of my room. I've built a monitor shelf to allow for my sweet spot to be a bit smaller and got rid of the TV on the keyboard stand so my desk can be pushed right up against the wall. I already noticed a better sound from the below set up compared to the above.
I would suggest that you get your speakers completely off the desk, onto stands behind the desk, up against the wall. Then you can use the "walking mic" test to find the optimal location for your mix position. The procedure is here: Soundman "Walking Mic" test procedure, for finding optimum mix position location (and other things)

Once you find that initial "best" location, move the desk up to the mix position and locate it so it is comfortable for you to work at with your head at the spot where the mic was.

Next, you can do something similar with the speakers: sliding them further apart in small incremental steps, with REW measurements at each step, while also changing the angle to keep them aimed at a spot about 18" behind that "best" mix position, then looking at the data to find the best spot for the speakers... and finally repeating the "walking mic" test, but just over a small range of distance this time, to see if there's a final "even better" spot. There's no need to do the entire room this time: just a small range around where the initial best position was.

I would also suggest replacing that desk with something that is lower profile (no shelves or other things sticking up above the work surface), and as small as possible. Desks can have an effect on the acosutic response of the room, and in general it's not good to have the speakers on the desk either.

With that setup (everything in the "optimal" location), you can then start treating the room. And once it is treated: repeat! Try optimizing the mix position and speaker locations one more time, with the treatment in place.

I have a hunch that your room can be really good...
