I’m currently checking that all the hardware is working ok on my new 11th Gen (Ubuntu) and 12th Gen (Windows) laptops - but it seems I can’t easily check the individual built-in mics (“dual MEMS”). Both OSs are geared to testing a single (mono) mic; likewise the Windows Voice Recorder app only seems to offer mono record/playback.
My background is in broadcast engineering (BBC, Channel 4 UK) and in the past I’ve come across instances where someone has (allegedly) made a stereo source mono by taking just the left channel (rather than by adding left and right and reducing by 6 - or possibly 3 - dB). That’s the easy way to do it, of course - but it’s not the right way.
Before I install Audacity to investigate further, just wondered if anyone knows/has worked out how the Framework dual mics are treated when using the OS to test the built-in mic or with apps that are mono-only.
