Mis amigos, this looks to be almost the ultimate room acoustics...

Please read it, tell us your opinion about it. Happy listening!

While reading the article (I just skimmed through the first part), I couldn't help but think about a recent 'update' ("Quarter Notes") from Jim Smith to his book "Get Better Sound", where he states:

"If you have a mid-bass peak in your room, you could possibly reduce it with EQ. And that may be your best choice.

But remember that the peak is almost certainly from a room resonance. When you turn it down by eq’ing it, you are simply turning that whole frequency area down in amplitude. Actually, you haven't removed the resonance from part of the sound. Its percentage of the fundamental will still be similar, only turned down a bit (well, it will usually be a somewhat smaller percentage to some extent because it’s not resonating as loudly).

So this correct-amplitude bass note will still contain an inordinate amount of resonance even if it is reduced electronically."

So he is suggesting room treatment before applying any EQ.

Hey Bernard,

The standard rebuttal to this POV, from Harman and elsewhere, is that sure, the resonance is still there, but since the offending frequency band has been attenuated by the EQ, the resonance (undesirably long time decay) has been pushed below the noise floor - i.e. it's now inaudible. I've yet to find a cogent response to this logic, though there may be one. Having said this, I don't think anyone would disagree that DRC should be used only after optimizing speaker placement and room treatment.

To the OP, I've been following Accourate and a similar product, Audiolense, since their inception. Both look like terrific products and I'd love to have a software-based solution, but both appear quite unwieldy when compared to comparable SoTA hardware-based products e.g. Dirac (in Datasat form) and Trinnov. Then again, they're an order of magnitude plus cheaper.

As the guy on the forum with the most treated room, I can attest that yes, doing the physical treatments first is highly recommended. However, that does not negate the need for DRC as well.
A well applied DRC can still improve any room and the results can be magical.

The differences between DRCs are many, but the hardest part about all systems is the measuring process. I've yet to see one of the systems enhance the measurement process to the point an average user can get a good result the first time out. They all require study, practice and iteration to get the best out of them.
That said, the new Accourate software looks like it has advanced a lot since I looked at it three or more years ago. I'll have to check it out. Gracias Roberto for the heads up on this.
