Sound Association v3.0
A noisy computer is a good computer! Put your .wav files to good use and assign them to all of your most-used programs with this free utility. Sound Association (formerly Souser-Sound Association) lets you easily assign sound events to any Windows executable file. For instance, you can have a specific .wav file play when you open Word, another when you fire up Notepad, and still another when you launch your Web browser. Besides "Open" sound events, you can add hooks for Close, Maximize, Minimize, Restore Up, Restore Down, and more. Just type in the program's "friendly" name, browse for its .exe, and check off the sound hooks you want to add. Then, push a button to go directly to the Control Panel Sounds area to assign .wav files to your new sound events.
