Hi! Since the beta 136 (I think), the phase graph in the alignment tool is not changing when altering the delay.

Hi John,

The phase of the loudspeaker whose delay is adjusted either via Delay of Fine delay within the Alignment tool does not change on beta 140 when "Show phase traces" is selected

Thanks both, that's fixed in beta 141.

Running through a delay range on the alignment tool via the API is significantly slower than what it used to be, Nearly 3 minutes on a M4 Mac to cover 18ms at a rate of 0.03ms. Comparing against 135, it was usually done in about 5 seconds.

Great work John!

Couple of quality of life requests for he RTA Stepped sine window.

• Can the Level setting have the same level picker as the usual generator and measurement window?

• Can the "capture distortion compensation data" button be a checkbox selection?

Thank you.

Can the "capture distortion compensation data" button be a checkbox selection

It's a button rather than a checkbox as when it is selected it clears any current compensation, having it as a checkbox would be more likely to cause inadvertent compensation removal.

Can the Level setting have the same level picker as the usual generator and measurement window?

That's on my to-do list, but it takes up a lot of space and the dialog is already very tall.

Alignment of measurements with impulse responses takes longer with proper phase smoothing. You can either generate magnitude + phase copies of the measurements and align those, or use a variable step size so that you do not evaluate the alignment at so many points. Depending on your evaluation criteria a form of golden section search may be suitable, even if only to narrow the range after an initial coarse search.

John, is there any hope that later we'll get back to the same speed of the alignment tool as in the 135 version?

For saved RTA measurements with "show distortion", the overlay popup on the SPL & phase chart is disappearing when I select different saved measurements. I change tabs and go back to SPL&phase and it will re-appear.
