I've got a question for anyone who has done an acoustical anaylsis of their studio. When you are measuring the frequency response of the room and the RT60, where do you place the mic? I'd assume that you would place it right where you sit when mixing, but are there any other locations that are benificial, like measuring the entire room in a grid pattern.

Also, if you could pass on any good links about acoustical analysis, I'd appreciate it.

Thanks for the help.
 
i am interested too... and what software to use.. ETF Acoustic ??? other?? is there good example with pictures of acoustic measuring..
 
We are using Smaartlive by SIA. It has a 30 day demo available.
 
Mada,

Yes, the mix position is your main concern, but you also need to know how a mix sounds to clients who are sitting in on a session. So if you have a couch in the back of the room, or in the front, you'll need to know the room's response there too.

Wow - this looks great! I hope to be buying it eventually, but do you know if the demo is feature limited in any way, or just time-limited?

Thanks,

So far it looks like it is just time-limited. We haven't hit any roadblocks yet.

Ethan - Thanks for the advice. That makes sense.

Anyone else have any advice or suggestions for performing an acoustical analysis?
 
What kind of microphone/preamp are you using with this? It looks like they recommend an expensive measuring microphone combined with an external preamp.

One alternative that should work FINE is a mic that they talk a lot about over in the microphone forum here on Homerecording.com -- the Behringer ECM8000. You can get one of them for about $30.-- which is a LOT cheaper than the expensive measuring microphone. You can also use it for certain things, such as drum overheads later. Be aware, though-- it requires phantom power, if that's an issue.

A lot depends on if you are measuring a control room, or a tracking room, or a combination room.

If you are measuring a room where you will be recording, as opposed to listening -- I'd take lots of measurements, maybe on a grid of some sort, in order to identify any places where there might be standing nodes that you need to address. Ideally, you want a room that sounds good everywhere you want to put a microphone.

We have access to B&K mics and preamps.

Thanks for all the help, and if anyone has any other advice it would be appreciated as we are planning to start the analysis later this week.
