From the developer:
Recordia is an application that lets you record audio directly from the menu bar or with a global keyboard shortcut. This can be useful for recording voice memos, song ideas, meetings, lectures, interviews, phone calls, voice-overs, and more. The tool supports customizable keyboard shortcuts to start/stop and pause/resume recording.
