I do have one feature request that may be useful. Excess group delay and minimum phase calculation. I have been transferring EASERA data to ARTA or sample champion just to get this information recently. I think it will be a useful function since a lot of other measurement system has this.

We will add the "Excess Group Delay" to the new features requested.
Thank you.
We want to mention that we have included the new sophisticated "Delay Analysis" in the new version of EASERA SysTune. It is recomended for the time alignment of loudspeakers.

I had assumed you used Excess Group Delay within the frequency range of interest in SysTune's Delay Analysis module, which seems to be what you're implying Waldemar. :)

Standard, minimum and excess group delay plots can be extremely useful in tuning as they can reveal what is minimum phase (thus a good candidate for EQ), and what isn't.

One of the clearest discussions I've seen on this can be found on ppg. 50-53 of the help file for the REW v5 measurement software:

It would be wonderful to see these plots added to SysTune Pro as well as EASERA. :)

Thank you, Langston.
We know that text.
If you use the Delay Analysis in SysTune, you can easily find the best Delay, without inspectation of the Phase or Group Delay.
Nevertheless we will discuss to add those plots to SysTune as well.
