OCA's video first steps but PEQ as a result ?

[Darek K]

OCA made the video "REW (Room EQ Wizard) Top Tricks: Convolution with Inversion (no EQ filters, all FIR!)".
The result of this work is filters saved in a WAV file.

Is it possible to convert a WAV file into a bin file that is acceptable by MiniDSP 2x4HD?
I'm guessing not.

In that case, is it possible to follow the first few steps in this video, but instead of producing WAV files, create PEQ filters as the result?
Would it make sense to do everything up to 14:42 and then create the filters in the EQ window there and save them as txt files (to then load them into MiniDSP as PEQ files)?

It would good to show some consideration for the people you are asking for help by linking the video, instead of making us search for it.

!!! SORRY, really sorry !!!

I dont'like links like this because of insted of simple text link there is whole video "frame".

Hmm. I am brainless.
First step in this video it is time alignment.

Second step this is SPL alignment

And than we go to EQ window to produce only valid house curve.

But I consider to produce whole filters in this window and export them to txt files.
This is my question - is that make sence ?

This video is about creating a convolution filter, its different to PEQ filters. Generally speaking if you are producing PEQ filters I wouldn't use this video as a reference.
For PEQ filters you should be able to find plenty of simpler video's on youtube - ie one that uses a target curve made up by the video creator. I use a straight line 0.3dB / octave slope. It can be a steep learning curve, and it does just take time playing around with REW.

This video is not relevant for you. The video is about making FIR filters. You need IIR filters.

The first step in that video is to time align the left and right speakers. This assumes that you managed to place your microphone exactly between the L/R speakers and there are egregious differences between them. Otherwise, if your mic is a few inches closer to one speaker compared to the other, you WILL see a time difference between L/R. Not only that, but this measurement is almost impossible to replicate, and it's also irrelevant if the time discrepancy is small. I recommend that you should skip the L/R speaker time alignment step.

Note that L/R time alignment is not the same as main speaker - subwoofer time alignment!

If you are generating PEQ's for the MiniDSP, I suggest you follow MiniDSP's instructions. I don't know if @OCA made a video about generating PEQ's for MiniDSP, but the instructions on MiniDSP's webpage should be adequate.
