John Mulcahy's latest activity
-
John Mulcahy replied to the thread STI signal and measurement.REW's STI calculation uses the indirect method, so it uses an impulse response. You can get that by making a sweep measurement. The STI... -
John Mulcahy replied to the thread How can I get longer IR for limited-bandwidth sub measurements?.Sure, change the Analysis preferences below. REW adds 1 second before the IR peak, so the overall length would be 1 second greater than...

John Mulcahy replied to the thread Frequency Normalized Distortion.It is doing it. Choosing the plot harmonics option forces use of harmonic as ref, so whether the THD plot changes depends on whether...
-
John Mulcahy replied to the thread Frequency Normalized Distortion.Not really. From the help: Plot harmonics at the harmonic frequency changes the way the harmonic orders for sweep measurement...
-
John Mulcahy replied to the thread Advise to interpret REW measurements.A mic fault is unlikely, but a very long USB cable could be a factor.
-
John Mulcahy replied to the thread Generator Output High-Pass Filter??.Difficult to be sure what you are referring to or what you did when you measured the output. You can see the REW stimulus on the...
-
John Mulcahy replied to the thread Frequency Normalized Distortion.That's the "Use harmonic frequency as ref" option.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.How long is the FSAF file? Does the Measure dialog open in FSAF mode when you get the delay or is it in SPL mode? Is there a Busy...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Yes, please.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Doesn't give me much to work with. Every time you open the Measure dialog or only the first time? What are your Measure dialog settings...
-
John Mulcahy replied to the thread Advise to interpret REW measurements.Clock adjustments are all over the place, anywhere from -3 ppm to -255 ppm. That will alter the shape of the IR but won't change the...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.No need for a video, problem has already been fixed.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.I guess the level was -3 before you changed it to -9.7? I have fixed it for the next build.

John Mulcahy reacted to xPoiler's post in the thread I made a free easy to use (Open source) advanced room correction software that leverages REW's API with
Like.
Hi guys! I got tired of generating filters with trace arithmetic in REW by hand, it can be quite the time-consuming process if you don't... -
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Are you sure the Overlay graph had the Y axis set to SPL? The SPL offset doesn't affect other axis choices.
