Spek now has a fully functional Windows port! The installer bundles GTK+, GStreamer and all their dependencies, you don't need to install anything else.

I also moved project hosting over to Google Code so Spek now has a full-fledged bug tracker. The source code is hosted on Gitorious GitHub.

If you are tired of starting up monstrous applications like Adobe Audition or Audacity just to check a file's spectrogram, give Spek a shot!
