Login & Awake Sound is a tiny, but very useful app, that enables you to specify a sound or a music file, that is played every time you log in to your Mac or when your Mac awakes.
It's simple user interface lets you specify which sound file you want to be played at login or wake up.
If you were a windows user, that has migrated to Mac OS X and you are missing the log in sound, this is the app for you.
If you have a very long sound and you want only a portion of it to be played Login & Awake Sound can help you. You can specify a range from where to where the sound is played.
