SimpleSound is a utility from Apple Inc. that debuted with Mac OS 7.5.3 in early 1996. When Mac OS 7.5.3 was released, the Sound control panel and Monitors control panel were merged into one (and for users of Mac OS 7.5.2, the Sound & Displays control panel was taken away. Mac OS 7.5.3's replacement control panel, the Monitors & Sound control panel, merged the Sound and Monitors (separate) control panels, but did not feature a Record button. The Record button is hidden away in SimpleSound. SimpleSound can also, via its Open command, open sound files and QuickTime movies (soundtrack only).
