Acourate is one of the best possible software solutions for speaker and room correction. Its generated convolution files integrate perfectly with Roon.
Now, version 2 is out! It has been completely overhauled and is much easier to use with more of the most relevant radio buttons now being directly accessible.
And the real good news: Using it with the same parameters and the same measurements it sounds even better: More transparency and more detail! Wow!
The new Inter-Channel-Phase-Alignment (ICPA) functionality is a boon for those not having the perfectly symmetric room. It solves a key problem in the modal frequency region. This leads to a more coherent bass sound.
If you have already got Acourate: The update is a must. If you haven’t got it yet: Go for it!
I’m downloading my upgrade to v2.0 now. The wait is agonizing. LOL.
I agree that Acourate is one of the most valuable “components” in my audio system. Right up there with Roon and room treatments. My room sounds great without corrections, but results with Acourate filters are astonishing.
Edit: download finally complete. It seems to work. Here’s a quick before vs. after vs. target for amplitude correction with the new UI. I really like the new buttons for macros 0 - 6.
I need to spend some time practicing with Macro 6, but creating an ICPA correction will be so much faster and less error-prone than what I’ve been doing manually with v1.10.4.
I’m kind-of bummed that there’s no quick way to create the ZIP file for Roon’s convolution engine like there was with v1.10.4. Either that feature has moved or been removed. Not sure. No big deal to zip up the stereo WAV files manually, but I can’t think of a good reason for Uli to have removed it. Perhaps it will come back on a later release of v2.0.
I do. I’m re-working my filters this afternoon with V2 after adding a pair of SVS 3000 Micro subs to my system. I’ll post my progress and results somewhere…probably on Audiophile Style since that’s what I did last time.
I had intended to do this yesterday, but the system sounds so good after integrating the SVS subs by ear, I could not tear myself away from the music long enough to drag out the mic. I’ve had REL subs in my system, but there’s something special about these new “audiophile” SVS subs.
The benefit of the pre-filter is that the corrections are applied without smoothing, enabling them to be more precise. Applying corrections without smoothing only makes sense at lower frequencies, like below ~200 Hz, where the wavelengths are longer.
That’s one part of the story. Sometime the room mode peaks are way above the average other frequencies, say 10-25dB. Without pre-filter you then need to reduce the level for all other frequencies too much. You should aim below 10dB reduction. This is why knocking the modes out 1st makes sense.
