I just realized that a moment ago. This points out a simple improvement: Change the error message to say that you need to use "measurement sweep". The current error message is confusing as it emphasizes version mismatch. Plus of course the NullPointerException is a bit scary :)
Hi,
I get "Data missing" "The sweep file does not contain data REW requires to generate the measurement, please use a sweep file saved from this REW version" error when trying to use externally recorded sweep measurements.
Steps to reproduce:
1. Export sweep from generator (logarithmic, 32-bit...
Here's an mdat which shows the problem.
I applied Psychoacoustic smoothing to L1, pressed "Average the Responses" (with only L1 selected), then chose the "A / B" trace arithmetic with L1 as A and Average as B. Resulting response is -240 dB at all points.
The RTA works for placing a single speaker (or sub), but doesn't show if there are significant differences between two speakers (which would screw up stereo imaging bigtime).
In that case, it appears that A/B has a bug that makes it unusable if the first response is original but the second response has been generated by averaging. In that case the resulting response is at -240 dB for all points (or a NaN is interpreted as -240 dB).
My use cases are comparing the...
Hi,
Another low hanging fruit:
Add feature to calculate dB(A) - dB(B). This should be trivial to implement and would be useful to separate the effects of comb filtering / modal ringing (can't be compensated with EQ above 100 Hz) from general tonality (can largely be compensated with EQ).
Hi,
Here's a feature that should be simple to do:
Add option to automatically measure two outputs (L&R typically) in succession. This should speed up finding optimal speaker / room treatment placement quite a bit.
Hi,
I've found applying -3 dB / octave filter very helpful in determining where to place absorption for early reflections. It removes the inherent excessive weighting of high frequencies in IR / ETC plot, while keeping the IR features / reflections visible. However, it's quite tedious to...
