Test mp3 quality, delete crapola

Situation: I have a large collection of mp3, Flac, ape, etc. files collected over the years. I also have Spotify.

Complication: Many of my files are very old and are encoded in low bit rate, poor quality formats/codecs.

Resolution: Time for a cleanup of old crapola cruft.

I would like hazel to:

1. iteratively go through the folder
2. Find mp3 files
3. Check the audio quality (e.g. Is it less than 320kbps?)
4. If yes on (3), delete

I can do everything other than (3).

Can anyone give me a solution for checking/testing the bitrate of an audio file in Hazel?

If you select "Other" in the attributes pop-up in your rule condition, you can see what metadata is available on your system. On mine, I have Audio bit rate. If you have that too, it's worth trying that. If you don't, then you can do one of the following:

- Find a Spotlight importer for mp3s which does import that data.
- Use a script condition in Hazel to run some program which can extract that info.

You can use Hazel's preview function to see the values of various fields while editing your rule to help test things.

Other doesn't work.
OS: macOS Sonoma 14.0 Beta (23A5328b)
Hazel: 5.1.1

How to repeat the issue:

1. Create a new rule
2. Attempt to select other

Outcome: Dialog box flashes briefly and then disappears.

Sorry about the harsh contrast in the iPhone video - not sure what is happening with it)

5.1.1 is very out of date. Try updating to 5.2.2. Note that the in-app updater may be broken in which case I suggest downloading and installing the update manually.
