Does crossover auto simulation software?

[doug20]

I have wave files of my impulse measurements.

Is there anything on the market that takes those measurements and optimizes a crossover for them?

I am not sure I understand your question but LEAP will generate a crossover using a Wizard format more or less automatically. It can also run circuit optimizations against a Guide curve as well from an existing circuit and measurement set.

Yeah, that is what I was trying to ask. I forgot about LEAP. But Madisound LEAPs program only works for drivers they sell.

I have wave impulse files and I would think a software package could take those files and create crossover simulations.

Hi , I wanted to ask this for a while, Do you think It worths applying that onto an LF something like a JBL 2235h ?
Or rather HF benefits?


BTW this one can do it , too, be sure to watch tutorials:

(((acourate)))® - Room Correction, Speaker Optimization and Sound Improvement

[doug20]

thanks!

Crap, The STransform software package can not import Wave files yet. Would have been cool to see my response in 3D. I have to see what other types of files HOLM can export.

Trying out Acourate demo....very, very limited.

pretty well I get to this point (imported my wave files)




But I can not do much more. I have to find some help files on it.

[doug20]

Acourate will not generate a schematic for passive crossover network correct?

[tritosine]

Well, there is a lot to read there, perhaps start with the whitepaper If you seek for phase coherent design apart the usual inverted frequency plots.

As far I understand the basic concept , you want to generate those correction coefficients afterall and those can get LOOOOONG both in terms of computational resources and processing time involved, so I pretty much gave up on it because its not really suited for my embedded app. Im toying with an esl57 now anyway.


-No passive crossover , passives can't do what is depicted in the whitepaper.

[doug20]

So its really a PC based DSP solution? It won't generate values for me to plug into my DCX?

btw, I like the interface.....not hard to figure out. Measurement packages seem to fail at that user ease of use thing and the toturials are great.

[tritosine]

Ah its whole different than the DCX, this one is brute force FIR, whereas the DCX is rather cheap analog-alike IIR algo.

Also this one prefers low order filters , and using low order filters is mandatory once you stay phase coherent .
I just dont beleive the DEQX marketing fluff that its both steep and both phase chorent because byproducts cancel between drivers.
