Peter Verkhovensky recently wished out loud on Twitter for a feature in MarsEdit. He wanted the application to play a sound when a post has been sent successfully to a blog, similar to how Mail can play a noise when sending a message.
Although MarsEdit doesn’t have built-in support for this, it turns out to be relatively easy to achieve if you take advantage of the built-in Growl support. Growl is best known for its ability to display small, floating notification windows when certain actions are performed in applications, but it also supports the ability to play a sound.
Peter describes the process of adding a successful post sound in this manner. Nice work, Peter, and thanks for sharing the details on how it was done.
