Okay, reporting:
the "0" thing didn't work out (it just keeps spinning forever) but EQ filters as low as 1ms build okay.
Also somewhat strangely, if UI is to be trusted (the red line when filter is built), the 1ms EQ filters follow the specified "blue line" curve closer than ones built with default settings.
As soon as I get an external card with TOSLINK-in I'll check just how compliant they are with desired curve "on the wire" (a matter of curiosity plus guy was selling a decent-looking external audio card for ten bux. I'm ready to spend ten bux on curiosity!)

With a minimum phase filter there is nothing to optimise. Turn that off and 0 will work just fine and be as accurate as the filter length allows as in the example above.
"zero" works out without optimization but the "red line" ends up being differently shaped. Not by a huge deal but different. Might eventually compare to 1.45ms filter produced from same settings (maximum optimization, UI shows red line perfectly tracking the blue one) using the TOSLINK-in usb thingus (still in transit) and report if any interesting differences exist
That indicates there is not enough taps to accommodate that filter shape without some compromise. If you are using a computer as a source then either Equalizer APO, Jriver, CamillaDSP or others can run any length of convolver filter you want without any real latency. Jriver has the ability to add DSP to tracks that are then streamed to other devices.
I think he said he uses it OpenDrc
Should be 6144 taps at48k 64ms
Or 3072 at 96k plug-in iirc
even with the 48 K plug-in 64 ms isn’t even noticed on video that much, I have a Dirac that is 23ms on my HT and I can’t tell at all

Sure my point was to ask if the hardware was actually necessary, as if the source is a computer then the tap limitation can be relieved. As shown above with a minimum phase filter the latency does not have to be tied to the taps as it is with a linear phase one.
Sorry ,
Yeah I’m still a dummy about this roon and jriver
although it looks really really cool…
Okay I’ll be quiet now I’m gonna go bury my head in some of this and try and learn more 🐌

Hang Loose Convolver from Mitch Barnett, is very good for that purpose

Thanks fluid ,
yeah I just learned about roon , I am still reading about it . Never tried it
But it sure looks promising. And man I can get way more then 6144 taps and I can sample super high….🤩🤩🤩
what a brilliant idea

Oabei, are you going to flatten the phase for a passive speaker? The low end eats a lot of taps and can be hard to fix with too many bands.
Oh no no no…..
But I was thinking roon is something and I just found out it’s BORING!
wouldn’t it be something to have a cloud based correction… where a user could stream their apps through it, like title or Spotify or Qobuz. Most people wouldn’t ever need to buy a DSP or any hardware
no stupid silly core that is a dumb idea.
someone needs to invent this and unleash cloud based DSP….
you could simply tell your app what room you’re in whether you’re in the car or at home or at work and you will have a correction for each of your listening environments
so what is most of it is only two channel. all Suman would need is a measurement microphone that can interface with the app
There’s a lot of iPhone measurement mics like the one from audio control that are very good….
Could you imagine nobody would have to have any silly core or any silly PC running,
Their correction filters could be online and stream through your Music app it could interface with your other stuff that would be so cool!!!!!

Tidal should partner with Dirac…. Or pos and make something
Having it from the music app would be huge!!! Have a little chair with measurement points, could do it all from the music app, they have the music servers,
All they would have to do is add another server to run peoples corrections through
For like an extra two bucks a month or something..
it would know whether you were in the car or at home through GPS and it could automatically switch corrections
oh my gosh I’m a brain sometimes I have the best ideas but I bet nobody does it

on a sidenote: it is obvious that Rephase needs ajustments. dev promissed a new version...didn't come. what does he need? probably some reward, no? we could crowdfund a new version?! just an idea
Does anyone know how to make a cal file from a measurement?
i have a audio control mic that is very nice and sounds ten million times better then my umik1-2 and my UMM6….
the audio control cm-10 has no cal file, it’s calibration is part of the mic, and it’s XLR
I WANT my usb mics to sound like the audio control mic. Can I take a measurement with each and somehow make a offset and use it as a cal file for the umik?
pm me if can, I won’t bog this thread anymore with off topic… (you guys are the heavy hitters so I know if anyone knows , it’s you) 🙂 🙂
I’ll ask mods to delete this post in 2 days

Follow the process here and adjust for what you want to do

I had to apply myself to the read…. It’s perfect, I can apply this and modify a few small things , and it will work…
thank you so much!! 🥳🤩😎
It’s perfect.
Next question
mom tuning a guys car that has HQ player and roon
on HQ player I can just do a very high sample rate fir and HQ will downsample anything and work ???
and what is riff.wav ?

I am trying to convert my passive speakers to active by using powersoft dsp amplifiers..
I have done individual driver measurement with and without passive crossovers.Based on that I have figured out existing crossover points.
How do I go about designing crossovers in rephase? Is there a guide that i can follow. I am able to navigate rephase and was able to generate csv file to powersoft.
But I want to make sure what I am doing is right
