i have just completed a beta of instant player for os x. please go to the freeware page to check it out. for those who haven’t heard – here is a short description:
INSTANT PLAYER is a program which allows you to browse your soundfiles from the Finder. Start up INSTANT PLAYER, go back to the Finder, select a soundfile and press the option key. One can browse a large number of soundfiles by just holding down the option key and clicking on the sounds. This makes it great for looking through sound f/x or sample libraries. It will play the soundfile as soon as it opens it, so is also good as a browser helper application or as a drag and drop player.
