Benjamin Ragheb converted the script into a Safari Extension.

Regarding custom domain names. If your tumblelog is using a custom domain name — such as

foobar.tumblr.com — Tumtaster for Safari might not work on your site. If it doesn’t, and you want people to be able to download audio that you post, send me an email. I can update the extension to include your site.
