@pos,

Just wanted to say thank you very much for your wonderful software.

I was finally able to acquire a multi-channel DAC and add linear phase crossovers to the convolution filter mix. Here is a current in-room snapshot of the WIP.

Trying to learn a step at a time. Adding the additional channel convolution files is telling me my near decade old music PC is about ready for a heart and kidney transplant.

Here is an early vertical wavelet of the right channel, but it may not be indicative of just time alignment filtering disabled.

I should make another set of filters with just the XOs in place.

It dictates how many iterations the optimizer will do to try to make the resulting magnitude curve as close as possible to the target one.
If you have enough taps at hand setting it to "none" (default) is the best option.

I have saved files for Linear phase filters as texts files on many occasions. But I have no Idea how I did it. Can anyone help a senile senior citizen? Thanking you in advance for all the wonderful and amazing toys I enjoy!

Try the "format" dialog or use wav-files imported to REW that can also export txt-files..

I apologize for not being more lucid. The file is associated to notebook as opposed to rephase. A sample would be like this.

But if I add TXT to the file as I save it I am getting this, which is not helpful with my preamp Najda.

If you choose the text output option as Byrtt showed and press generate to save the file. Open that file in Notepad you will have all the coefficients as you want.

Perhaps you are looking at a Rephase settings file which is why it looks weird in notepad.
