jujumarie,
i know you are new and eager to learn but you need to read the FAQ page through and through to understand, ask questions related to fields under each thread instead of creating a post for each question that pops in your mind please, so we can keep this forum organized and not the same questions all over the place. those fields mentioned here particularly you have created at least 3 posts to ask different things re them. please keep questions in one place if they are about the same audios
i believe you have been adviced a couple of times to resesrch, read etc all those are basic answers you can find in FAQ
enjoy!
