REW Beta Release Error when generating minimum phase IR

[greatadrian]

Hello,

I noticed that when trying to generate a minimum-phase IR there is an error.
It occurs in REW 5.20 RC2 & RC3 (running on MacOS).

The error message:

REW V5.20 running JRE 1.8.0_252-release 64-bit on OS X 10.16, en, , UTF-8 at 127 DPI

I attached the project for which generating MP IR will fail. As an example, I imported measurement sweep against itself.

Many thanks for your hard work John!

Wish I had seen that yesterday. I have fixed it for the next build, in the meantime the bug can be avoided by generating the min phase response from the SPL & Phase graph rather than the Impulse graph.

Sadly, I noticed it only yesterday evening. I did also notice that similar error happens when MP Impulse Response is selected during WAV export. Not sure if it’s related.
Many thanks for looking into that!
