    Problem with RTA measurement

    My Win11 system doesn't do that, also running 24H2.

    Problem with RTA measurement

    There were some Win11 USB audio issues reported a little while ago, but I don't know which builds were affected.

    How to average the dB SPL of a measurement over a specific freq range

    You can use the graph metrics on the SPL & Phase graph to get average level over a selected span.

    Problem with RTA measurement

    That's certainly pretty strange behaviour, I haven't seen anything like that before. You could try the mic in another application to see how that behaves.

    Problem with RTA measurement

    The video is blurred so I can't see what the input is, what driver you are using or what REW version. If you are on Windows use the Java drivers and choose the input for the UMIK that starts "EXCL".

    Arithmetic shows additional gain +3dB

    Use the SPL axis.

    REW Beta Release REW API beta releases

    Yes, that's because it is the unfiltered result which is used by the FSAF processing to extract the impulse response. I can add an "excfilt-" file in the next build that has the actual output data. The residual can be played back using the system default WAV player via the button in the...

    REW Beta Release Issues with 5.40 Beta 99

    Thanks, I can reproduce that. The arithmetic result is briefly selected before selection returns where it was, but control updates in the EQ window while that is happening end up sending a value from the arithmetic result to the selected measurement. I'll fix it in the next build, in the...

    REW Beta Release Issues with 5.40 Beta 99

    "Generate measurement" meaning what? Targets are specific to measurements, changing the target on one measurement doesn't change it for others. New measurements get their target settings from the defaults in the EQ preferences.

    REW Beta Release Issues with 5.40 Beta 99

    New measurements are selected by default for the overlay windows, including All SPL. If you open an mdat file saved by V5.40 the selection status is remembered from when the file was last saved. For files saved with earlier versions that selection status defaults to not selected, but I can...

    macOS also working fine for me. Please try beta 98 to confirm that is OK for you.
