Thanks

Using the signal generator can work, but using some kind of spectrum display gives you much clearer info. If nothing else, sweeping a sine wave and listening can be quite revealing. As I said before, I would avoid graphic EQ's completely(most digital emulations also emulate the drawbacks too) Presonus and Behringer analyzer mics are actually quite adequate( I bought the Presonus for less than $50 on a special a few years ago(even though I already own the Audix measurement mic)

At our studio, we are still on Pro Tools HD10. Some of the newer room correction plugins are only 64 bit, and won't work with our system. We use instead a MiniDSP DDRC-88D running Dirac Live 3.0 for our room correction. No Pro Tools plugin needed. The MiniDSP comes with a measurement mic (with a calibration file). Together, they are a very powerful system that I would call a "game changer".

That looks like a great option, and they have smaller versions(less IO) that are less money.
Have a look at this one:

Totally!! It really is a great option! Sounds incredible. Mixes have been translating so much better. There's only a handful of the MiniDSP boxes that work with Dirac Live though. Here's a link to the page.

We went with the DDRC-88D (Digital) because we needed 4 inputs and 4 outputs (L+R+SubL+SubR) plus we wanted to use our own converters. Their DDRC-88A (Analog) would have been my second choice, but then we'd have to use their converters, which I've heard aren't that good.

Has anyone tried the Onyx3 Spectrum Analyzer App for IPhone & IPad? What do you think?

This isn’t particularly useful for measuring a room. You need an app/room corrector that generates swept impulse responses and measures frequency response over time.

Given the size of your room you’re going to have problems at the bass end and will simply not have enough room for really effective bass trapping. Auralex foam bass traps are not particularly effective. RealTraps are much better but you simply won’t have the space to install enough of them to fix the problems a room of your size will inevitably have. Small rooms with a similar width and length and probably height are a nightmare. A perfect storm of coincident room modes.

DSP correction is the way to go IMHO.

Would you elaborate please? Thanks

He menas that unless your walls are made of wood or thin paper, there is this thing called "room mode" and as a physical fact can only be treated with bass traps

No I’m saying in a room this small it will be impractical to get enough bass trapping in there to really fix the problem. They help but won’t go far enough, even with really effective traps which doesn’t include foam ones!

As a consequence, DSP room correction is the way to go, either with the hardware solutions mentioned above or the Trinnov system, or plug-ins like Sonarworks or the IK one.

If you put the dimensions of your room into a room mode calculator and assuming your height is the average 9 foot then you end up with near coincident room modes. In other words standing waves or resonant frequencies that are very close together.

In your case it’s really nasty at 125 and 129Hz. There are lower room modes at 41,52,and 63Hz which are too low for most off the shelf bass traps to suck up.

I have a similar sized room in terms of width and height and in my case, I get a spike of nearly 30dB at 126Hz at the listening position untreated and a major lump around 59Hz!!
