Cavern's FIRs don't delay at all with default settings, they are minimum phase filters. QuickEQ Home is using zero delay only, and Complex has a toggle for it that's on by default.Big latency
16500 does not give an audible delay.
Can this problem be solved?

Easy Effects and James DSP on UBUNTU have no delay for 16k samples Cavern wav convolver export, and give a noticeable delay for 64k

Sorry, I downloaded the latest version of Cavern, but no this option in complex mode

It's in Home only. Complex is getting phased out when every feature moves to Home, because Home is much friendlier to use.Sorry, I downloaded the latest version of Cavern, but no this option in complex mode

Why?!
In Home I can't adjust the curves for high and low frequencies, I can't make gain in safe mode, I can't cut low frequencies, there's a lot of useful stuff missing

Home version export 16k convolver stereo wav file, instead of 65.
Just uploaded a new version with increased Home convolution length (32k only, as 16k is way too small, but 64k is overkill), and added Equalizer APO (per stereo) to Complex, you can find it under the hardware export dropdown.

I spoke to a studio musician, he explained that the increase in length increases the delay. Is this true?
It's a common misconception of FIR, but it's not universally true. It's only true if the filter is zero phase. If it's minimum phase, it will have no delay. Cavern gives you both options.

Please remind me which setting regulates this?

Yes. Now it works, there is no audible delay when sampling 65k. But when I converted 2 mono files to 1 stereo, there was a delay. For this I used REW and Audacity. Do you have any idea why there is a delay after conversion?

Why is REW needed? In Audacity, you can pan one to the left and one to the right, but the per stereo export will do this for you.

It is a pity that VoidX removed the comparative quality table for export to various devices. WiiM does not support high quality equalization, only simplified export

Dirac already corrects to the selected target curves.
It could have seemed like aggressive marketing, even if the comparison was objective with the metrics stated in the docs.

Tell me, please, what equipment is needed for a PC to calibrate with Cavern and use equalization for 2.1 systems?
For the Smoother curve (EQ only removes the differences of speakers, but keep their general sound the same): any microphone, for full calibration: any measurement microphone.

Excuse me, I had in mind the means for playback. It is impossible to just buy a multi-channel sound card, connect it to a PC and display cross-made signals 2.1 to the subwoofer and an external audio amplifier? Cavern does not know how to do this? We need some kind of software crossover that divides the audio type into low and high frequencies
Equalizer APO. You can create a sub with a Copy filter and low/highpasses on the select channels. Don't forget to also do the downmixing, for example, using your system in quadro, and mixing the rears to fronts so one rear can be used as a sub out. However, PC 2.1 systems are usually active crossovers, you just have to calibrate a stereo.
