I found an issue. The volume seems to go down and get really weak after the program plays some SFXs. It seems to me like it forgets to turn the music volume back up after the sound effects get played. For me to listen any music sound at all I have to turn the computer master volume control all the way up as well as the soundsense volume control. The SFXs, though, are still as loud as ever, so it bothers me sometimes (I would like a way to turn down the volume for these sorts of things).
And if I start SoundSense after Dwarf Fortress, it won't play any music at all until the season changes. It is quite bothersome as sometimes it quits with some random error (trying to access not allowed memory, usually when the game log gets spammed with job cancellations or combat reports) and for me to listen to the music again I have to save and load again.
I think the achievements should be saved on a file with the world name, so it doesn't start all the way again in the same save file. These are great, really. I haven't revealed them all, but I'd like some secret fun stuff to come up. "Taming a dragon" and the like would be cool.
Other than that, I appreciate all the work you did. The songs are great and addictive. By the way, I am using standard Dwarf Fortress 2012 on a Mac OS X.6.8 Snow Leopard and Java 7.
