You are probably thinking of Sound Source AudioClips which included the SoundMaster utility. I had the Star Wars version:
The Macintosh Garden seems to have the Star Trek version available. I don’t think any of these were licensed – shows just how obscure Mac software was in those days that they could be sold in stores and still fly under the radar!
[If you still have the old files and want to extract the audio out of the old Mac sound files, you can use ResForge.]
