Avery Magnotti:

If you haven’t already heard, Apple accidentally published a prerelease build of audioOS through their public update servers. Whether or not this leak was “intentional” is up for debate, but I personally believe it to be a mistake.

Regardless, Avery dug in and pulled out a series of HomePod alarm sounds. If you are interested in the process (requires some Terminal/basic Unix skills), read Avery’s blog post.

For your listening pleasure, here are the sounds.
