I might be alone in this but I strongly disagree that tagging the audio with metadata is "an even better idea". File names are something immediately visible. They allow for sorting the recordings in a file manager. They do not rely on tracker or a similer third-party solution that understands the tags. They work regardless of the location (meaning, you can move the recording to a folder tracker does not monitor, or even to your PC or another device, and you will still know immediately all the important data about it). Last but not least, not all audio formats have the tagging capability.

I vote for file names. But whatever method you choose, Orecchiette will still need to have the capability to provide the info.
