In reading through the tutorial on recording from cassette (Thanks, WC!), I got to the recording test section and found reference to setting sound levels wherein I learned that the VU meter readings can be calibrated in dB or linear. When I place my mouse cursor over the meters and right click I learn that that Linear is selected and dB is greyed out. I then looked at Edit > Preferences > Interface expecting to find a means of changing the calibration to dB but there was no means to do so there.
I have screenshots but don’t know how to post them (yet).
Could someone please point me in the right direction?
