A few room impulses I captured

[Guitargodgt]

Yeah I have no idea if you will get any use out of these, none of them are studio spaces. This was my first time attempting to record room impulses. But I thought I would share non the less, names based on mic placement sine wav was generally played from one end of the room in the center and kept at that location for all mic locations. I'm going up tomorrow to capture the studio spaces (provided they are open to use) and take pictures of these rooms provided nobody has moved into the apartment yet.

This was a large studio apartment with a 12-15' cielings and one brick wall:

Apartment countertop.wav
Apartment left corner.wav
Apartment righ corner.wav

This was a concrete floor all brick wall room, but the ceiling was only 8' tall tops, there was amps on 3 walls and a rack of guitars on one. It's used to store the studio drums, amps, synths, and guitars.:

Basement amp room center.wav
Basement amp room corner.wav

This was the 2nd floor where all the offices and practice rooms are. All the practice rooms are tiny and carpeted so taking pulses from them seemed silly but the hallway wraps all the way around all of the rooms so I decided to take an impulse of that:

Floor 2 Hallway.wav

Ok and on the same floor they had a GIANT dance studio/ band rehearsal space/ actors rehearsal space. I didn't measure but this room was easily 60' or more long with hardwood floors. Unfortunately I don't think these came out all that well either as they still had a lot of the OC705 stacked inside waiting to be installed. But anyway:

Large room position 1.wav
Large room position 2.wav
Large room position 3.wav

Have you come across Altiverb? They already have an excellent catalogue of impulse responses from famous recording venues all over the world. Not sure what a studio apartment's going to add to that.

I use impulse reverbs. I'll give em a shot. Thanks for posting up.

guitargodgt... out of interest, what did you use to generate the impulse responses? I assume you recorded a sweep tone, then what software did you use? When I looked a while ago, had trouble finding one that would run on windows.

Cheers!

Let us know how you get on Greg

Okay, I tried em out on some drum tracks I had laying around. I applied them across the whole kit on a group track cuz that's how I roll. I never reverb the drum tracks individually.

I found these to be quite usable for my own tastes:

Apartment countertop.wav
Apartment left corner.wav
Apartment righ corner.wav
Large room position 1.wav
Large room position 2.wav
Large room position 3.wav

I did not like these for drums. Too bright and/or boxy:
Basement amp room center.wav
Basement amp room corner.wav
Floor 2 Hallway.wav

They may work great on something else though. All in all, they each technically worked fine and appear to be well done.

If you make any more, I'd love to have them.

I used a program called Voxengo Deconvolver to generate the sine wave and encode these impulses.

As far as the mics go, I wanted to snag a few so setting up was kind of a pain and I only had a few hours to record these (by myself, it would have been easier with another person helping) so I opted to use a Zoom Q4's onboard mics. The rig per say was fairly simple, 1 monitor hooked up to a laptop playing the sine wav and the Zoom Q4 on a mic stand at whatever location I put it.

The problem I had was the stupid fixed gain structure. Autogain setting would have been useless, so I had to re record several samples because they would clip (shitty) and I wanted to leave the gain on the hotter setting.

A starter pistol would have been easier, but in my reading of how to do these people have stated using a sine wav helps keep the noise floor down.


I only opted to do the apartment because it was empty, the space was large, and the ceilings were so high. It was still a fairly bright space. In the end it was more for the learning experience. Both studios were busy today so I couldn't make those other impulses I wanted. They probably would have came out better because of access to some nicer mics and monitors to use to make them, but like I said it wasn't in the cards today. They would have been dryer verbs with much shorter RT60 times but they might have been cool.

It doesn't surprise me that the hallway and basement spaces are crappy, it's not a space I would want to record in. I was just trying to grab some unique spaces you wouldn't find in a convolution reverb for the hell of it.

Also failed in getting pictures of these spaces today. <sigh>
