Is there a tool that preserves the audio? I want both, the transcript and the audio.

Quick glance; FreeFlow already saves WAV recordings for every transcript to ~/Lib../App../FreeFlow/audio/ with UUIDs linking them to pipeline history entries in CoreData. Audio files are automatically deleted though, when their associated history entries are deleted. Shall be a quick fix. Recently did the same for hyprvoice, for debugging and auditing.
