Hello - this is my first post I am in a little predicament. I write music for Videos and Promotional pieces, but nothing really for the web. I just got hired to write music for an online Video Game and I don't have the first clue on what I am doing. I am to write sound effects and scores, but I do not know what format to do it in, bit rate - nothin. I don't know where to even start. It is going to be an online MMOG - so apparently it needs to have specific parameters. thanks so much!
