hey folks,
I have recorded my sinus sweeps, white and pink noise in my new control room at 3 points (listening position and rear corners).
Now I have to figure out what frequencies are most disturbing.
I have recorded signals with a Sennheiser MKH 20, a Mackie 824 speaker and the Digi 002 Rack on my powerbook at high volumes, so I think the signal chain is pretty good.

Is there anyone who canm help me to interprete the results?
thx ,
this whol acoustic thing is very new to me,
thx a lot.

MKH-20 isn't the best choice for doing room measurements, but I'm guessing it will give us a good idea of what's going on... shouldn't be too far off.

If you could send me the original sine sweep file and the versions recorded in your room, I would be happy to help you analyze them, so long as there is a bit of silence at the end of the recordings... if not, my process won't work properly. Email them to me (use the button below this post) and I'll take a look for ya.

wow, thx that would be great!!
I will send them to you as a Zip,
cheers

eleo!!

Eike,

I'm sure you're in good hands with David, and I look forward to seeing what he finds. Allow me to offer a different perspective on this.

As I see it, there are three important reasons for people to measure their room:

1) To understand that they have a problem (many people have no idea how bad their room is).

2) Measuring before and after adding treatment to have hard proof of what was improved after treatment, and by how much.

3) To verify how good their room was made after treating it.

I use measurement primarily to:

1) gain insight into how much treatment is required and how it should be implemented.

2) aid in the placement of sources and receivers.

3) identify problems that predictive methods may fail to identify.

And best of All, unlike ETF or R+D the new DMF program is freeware, it's a bit like REW, but with additional remote options.

DMF actually runs REW as a native plugin.

I knew but wasn't sure I could reveil the DMF code ......
