Earlier quoted context omitted.
Per https://support.apple.com/guide/mac-help/control-access-to-y... you should be able to grant the FATpick app access to your microphone from that panel. It is likely you'll need to "install" the app (drag it to your Applications folder as prompted in the DMG), not just run the app directly.
I have the app in the Applications folder, but I am still not seeing it in the microphone access panel...
Hi royletron, for what it is worth I think the latest version (v1.4.2) now available at https://www.fatpick.com/support/downloads fixes this.
I think same updates that fixed the notarization issue may fix this problem also (since we had to add an explicit entitlement for the audio input). If it doesn't please reach me via the contact form at https://www.fatpick.com/contact-us or email me directly at rod@.
