I would like to see the "waterfalls", this will tell me the rooms decay times.

Also were you using an omni microphone when you did this test?

And where where you in the room? Were you in the 38% position?

Also what are the dimensions of the room and can you post some pictures of it?

About your test, Where the doors closed when you did this test, and how far away were you standing form the mic?

From what I see on this chart, you have a nice dip at about 245Hz, but it looks like most typical rooms.

Acoustics are counter-intuitive. If one thing is certain about acoustics, it is that if anything seems obvious it is probably wrong.

I was sitting on the stool I use when I do a lot of auditions or narration. I had my regular mic (TLM 103) in the normal recording position for me when sitting, and played the sound through my monitors (BX5s). I don't own an omni mic. My "booth" is in an 8x10 spare bedroom (there is a bed, a full linen trunk, an empty dresser and a 5x6 area rug). The door to my booth and the bedroom door were both closed during the test. Here is a video I made last year about my booth (it's a little embarrassing now).

I have since made many changes. First, I am using different audio equipment and have moved the computer out of the booth. I have also add a second ceiling quilt. I have put plugs (¾" particle board with foam seals) in the bedroom windows and added foam seals and a sweep to the bedroom door.

Is there an equivalent piece of software to FuzzMeasure for PC/Windows platforms?

I also wasn't sure what you meant by "waterfalls." What setting should I use for that? For the top graph, the software can do: frequency response, SPLs, mixed phase response, group delay, minimum phase response, excess phase response, or harmonic distortion. For the bottom graph, it can do: step response, energy decay curve, impulse response, log squared impulse response, or envelope time curve.

When measuring for the 38%, do I measure for the room as a whole, or for my booth? I am about ⅔ of the way back in my booth, but that places me right near the edge of the room as a whole given that my booth extends into the closet.

Also, while I appreciate the free help, honestly, I am not going to upgrade or change much at this point. With the teaching situation in the crapper and my wife changing jobs, money is going to be very tight. The window plugs were my last wife approved project for awhile, and I needed those badly to help cut out the noise bleed from the freeway ¼ mile away. Plus I have gotten mostly positive feedback on my auditions since upgrading my mic and interface, so I'm not too worried about the room.

So going back to my original question: I can use the rolls of insulation I already own as bass traps, right? They wont do a lot of good, but might help just a little. I was going to stuff them in the closet corner behind the GOBO behind the mic or up on the closet shelves. I could also shove them in the corner behind the dresser in the bedroom if you think it would help more, but they need to be hidden if they out in the room (per wife's instructions). If you have any other advise based on the video, I would appreciate it, but I can't afford to make a lot of changes. I know my setup isn't optimal, but I can't let the perfect be the enemy of the good.

Thanks again.

Apparently the same $150 price tag, there is something for Windows called ETF:

Don't know if there is anythiung for Linux or any freeware that does the same thing.[/url]

I found something called "Room EQ Wizard" at hometheatershack.com that looks really promising, and is free.

I haven't been able to get the Room EQ Wizard to work with my gear. It plays out through my Konnekt 6, but wont take input through it. Weird. Probably because it is a Java a Hobo Tounge

, so it runs on a Mac but doesn't have full driver support.
