If you're new to the audio thing, perhaps I can help you get going in the right direction. Basically, you've got two separate things, "soundfiles", and music. The soundfiles can be anything from a beep or a buzz sound, to thunder & rain, to a car crashing in stereo. They're played with a soundfile player, "Sound" being one of the best. Rename it as "Play". You'll see the term "IFF" associated with soundfiles, and that's just a type of format a soundfile has been saved in. The soundfile players, like Sound, play either IFF or non-IFF ("RAW") soundfiles, but if you're going to use soundfiles in a program, like DeluxeVideoIII, they'll have to be IFF. To convert a RAW soundfile to IFF, you use a sound editor, either commercial or PD. The commercial ones do a few more tricks, like saving in stereo, but for just saving a beep sound, a PD editor will work fine. The ultimate soundfile kick is getting a sound digitizing program, like FutureSound, and making your own. Along the same lines, you can often trade your own custom soundfile for a soundfile in a program, like a game. Music files fall roughly into two categories, self-playing and MODs. If you don't know what type it is, first just try entering the name in the CLI and see if it plays. If not, try a MOD player, such as MODMaster or EdPlay. You'll also want ITracker and MEDPlay for a few of them. It might even be a large IFF soundfile, so check that too. You'll see some other types of music formats out there, DMCS and Sonix being among the foremost. DMCS is, quite frankly, a piece of junk. The Sonix music is nice, but the instruments take up a TON of room and end up in one monstrous directory. MusicStudio is another music construction set, but never caught on much, not sure why..it's a fine program. Anyway, in this day of self-playing music files and MODs, DMCS, Sonix and MusicStudio seem as antiquated as Arc and Zoo. By the way, if you see a "SMUS" running around, that's a Sonix scriptfile. Well, that should get ya started!
