John Mulcahy replied to the thread REW Beta Release REW API beta releases.Phase unwrapping is relative, it has to start somewhere. The reference is the wrapped phase value at the cursor frequency. That's how it... -
John Mulcahy replied to the thread Feature Request: Simultaneous display of SPL Slow and Leq.It is just the Pro version for multiple meters. I'll give some thought to showing multiple measures on a single meter though.

John Mulcahy replied to the thread REW Beta Release REW API beta releases.Some images might make that clearer, but it sounds like it is behaving as expected. 450 degrees and 90 degrees are the same phase and...

John Mulcahy replied to the thread Feature Request: Simultaneous display of SPL Slow and Leq.What version are you running? The logger in the V5.40 beta version already does that. If you have the Pro upgrade you could also put the...

John Mulcahy replied to the thread REW Beta Release REW API beta releases.There's no need for them to be identical, clocks vary slightly with temperature so a slow change of adjustment between measurements is...

John Mulcahy replied to the thread REW Beta Release REW API beta releases.I did give that some thought a few years ago, I might revisit it at some point. There is always Spectrum Lab.

John Mulcahy replied to the thread Wy the much better measure with less noise did not show EDT T20 T30 ?.I have found how the extra traces appear, it's a side effect of removing a measurement. I have fixed it for the next build.

John Mulcahy replied to the thread Wy the much better measure with less noise did not show EDT T20 T30 ?.Yes, that's normal, it's the unit (seconds).
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Check for consistent clock adjustment figures for each measurement.
-
John Mulcahy replied to the thread Wy the much better measure with less noise did not show EDT T20 T30 ?.This is very odd, there should only be two traces in the legend for this graph, it seems to be showing traces from the SPL & Phase...

John Mulcahy replied to the thread Wy the much better measure with less noise did not show EDT T20 T30 ?.It indicates how well the decay matches the model of exponential decay + noise, smaller numbers mean a better match to the model...

John Mulcahy replied to the thread Wy the much better measure with less noise did not show EDT T20 T30 ?.You have to generate the classical results on the RT60 graph for the octave fraction you want to view.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.I don't see how. How would REW distinguish between renaming the LFE channel because it's not the LFE and renaming it because you want to...

John Mulcahy replied to the thread Is Pink Noise Misleading Me?.Yes, you are confusing the system response (which you are seeing when using pink noise) with the frequency content of program material.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.No. The spectrogram covers a time span, choosing a different reference for the pre and post parts of that span wouldn't change the result.
