Classic data is only available for 1/3 octave and 1 octave. I did.

Not a bug. If you want REW to retain your manual filters uncheck the "Auto EQ" box for those filters.

You would need to attach an mdat file rather than some images to get meaningful comments on the measurements. No input data and input selection reverting to default sounds like the mic is disconnecting, so USB cable length or connector issues.

Maybe, but a better route would be to use the API. Its purpose is to facilitate extension of REW's functionality, the /audio/input-cal endpoint allows calibration data to be read and written.

No, some preferences affect structures that are only generated at startup.

You could save the preferences after selecting and calibrating an input and reload the relevant preferences file as needed.

In principle that may be possible with one extra channel for the mic input (so 3 input channels in total). The impedance measurement input provides access to the signal at the driver terminals so it should be possible to derive an SPL impulse response from that and the mic capture. It would...

On the PC you are using ASIO, which treats devices as a collection of individual mono channels. On the Mac, or on PC when using Java drivers, inputs and outputs can be multichannel with a channel selector. L and R in the channel selector correspond to 1 and 2 in ASIO. There's also a L+R option...

Could you attach a screenshot of your REW soundcard preferences? 1 and 2 would typically correspond to left and right (L, R) in the REW channel selector.

No. Best to plug the mic in before starting REW.

Open the RTA window and click the "Stepped sine" button above the graph.

Presumably you have selected the UMIK as the input in REW? Does the mic work in any other audio application? If not, likely an issue between the USB port and the mic. Use a short USB cable if you aren't doing that already.

This seems to a bug between Tahoe and the Java runtime, the names for the inputs and outputs on some devices are empty. Nonetheless, selecting the empty entry seems to work.

The blank input is pretty odd, I see that too. Should still work fine with that selected though. I'll look into why it's blank, seems some output devices have blank output names as well.

The change was made in V5.40 beta 127 released 7th June.
