RecAll for Windows has been popular for use by amateur radio operators, small airports in certain countries that are required to record and save radio transmissions, and small businesses and telephone call centers that need to record telephone calls. Imagine the possibilities of using a small portable low-maintenance low-power Android device for the same application.

Before uninstalling: The RecAll app does not request storage permission, using its own private directory. Be sure to save or share any audio recordings you record with the app prior to uninstall, since audio in the private directory will be deleted during uninstall.
