Read the rest of this update entry...Changes in V5.20 beta 39:
- Provide more precision for the left and right window width settings
- Moved the RTA average count panel to the bottom left corner of the graph
- The signal generator maximum frequency is based on the chosen WAV sample rate when Save to file is selected
- Added a button to close the FlexASIO control panel
- Added slope choices from 6 to 48 dB/octave for the Subwoofer and Bass limited speaker targets
- Improved scope triggering for high frequency...
Lots of strange things going on in your system. If REW lets you manually calibrate a UMIK-1 it is because it doesn't know the input is coming from a UMIK-1. Can you attach a screenshot of your REW soundcard preferences?I have UMIK-1 and I uploded calibration file (checked twice) but the noise floor was showing only 9 dB. I wish my room would be that silent but I'm sure this was an error.
My measurements with 5.19 version were somewhere at 100 dB on a scale. With an upgrade to 5.39 they were 40 dB lower.
I then guessed some numbers (from 80-85 while my SPL meter was showing 32 dB) when doing calibration to get a matching scale. However, with 5.19 version I got max value at 122 dB anad with 5.39 this number is 126. The plots are now on a same scale.
It doesn't bother me any more but I though you should know this.
REW was only looking for the FlexASIO PortAudioDevices.exe file under Program Files, I will have it look under Program Files (x86) as a fallback.OK, update. since today (and after restart yesterday) ASIO drivers are not working in 5.39 version.
Looks like some files have been deleted while uninstalling the 64-bit version. I had both installed at the same time).
I downloaded the 1.5 version here:
Install folder by default is Program files. But REW is not giving me ASIO as a choice.
I uninstalled it and choose Program Files (x86) folder. Asio is now found in the device dropdown menu.
But I still didn't get the sound out from the speakers.
When ASIO control panel is clicked I got an error message below. Interesting, the same message occurs when Asio drivers were installed in Program Files folder ...
I then copied FlexAudio content to both locations. I'm now able to measure again. The calibration process is now not allowing me to enter my own number so I will try to match the same level with "level" field in measurement window.
Ok, thank you for the tip. Where can I get this file?You need to load the cal file under the FlexASIO device, since that is your input source. You have the file loaded for the Java drivers input. If you click the Cal files button on the Measure dialog you should see there isn't a cal file loaded currently.

- The dual added mass method for Thiele-Small parameter estimation, developed by Claus Futtrup and Jeff Candy, has been implemented. This method provides a very accurate Bl estimate that is independent the driver impedance model and provides a "ZM*" model of the driver motional impedance around resonance, allowing accurate extraction of Mms.
- The driver motional impedance model has been changed to accommodate...

- Added crossover filters to the DCX equaliser option (Butterworth 6, 12, 18, 24, 48 dB/oct, Bessel 12, 24 dB/oct, Linkwitz-Riley 12, 24, 48 dB/oct)
- Added crossover filters to the Generic equaliser option (Bessel, Butterworth and Linkwitz-Riley up to 48 dB/oct)
- Bug fix: The measurement trace was disabled on the EQ window filter adjust graph

Impedance measurement has received some attention in this release. The impedance measurement process uses the difference between a reference channel and the measurement channel to calculate the impedance. If there are differences between the frequency responses of the channels, as there typically will be at low frequencies for AC-coupled inputs due to component tolerances, those will affect the result. The impedance of test leads...
