UMik-2 cal file - not a recognised USB mic

[dlr]

I load the UMik-2 cal file using the measurement dialog "Calibration files..." that brings up Calibration data window. After entering the file the window pops up a message "The cal file has a Sens Factor entry but the input is not a recognized USB mic. The Sens Factor will not be used. " The file is a raw txt file with serial number for filename, but nothing to indicate the make of the mic. Why is it not accepted?

"Sens Factor =-10.77dB, AGain =18dB, SERNO: 8111506"

The UMIK has not been selected as the input, as far as REW can see. That might be because the input device and input have been left as default, or it might be because the input is oddly named (can happen on Linux, for example). What input device and input are shown on the soundcard preferences?

I'm using FlexASIO. I just saw that it had "Microphone" for input device, I changed that to "Line (Umik-2)". The Windows setting had been and is "Line (Umik-2)". I set FlexASIO Input to Umik-2. It seems to load now, no message popup. Just ran a new measurement. The db level _seems_ to be what I would expect, but I have no way to verify calibration.

Is there not some way to use the sound card ASIO driver, yet use the microphone direct input without a wrapper such as FlexASIO?

No, because ASIO is structured as a single device protocol. Wrappers like FlexASIO create a pseudo ASIO device that under the hood is separate devices for input and output. For measurement purposes there's no benefit to ASIO over the WASAPI Exclusive Java drivers (device names starting EXCL).

I switched to the Java drivers. Works fine that way. Better in fact. I've been having occasional glitches during STHD and multi-measurement averages. Possibly due to the old laptop with FlexASIO I've been using. So far the Java driver has not exhibited that.
