I need a web player for an on demand streaming site. This site should be playing music from music folders and advertising spots as well when user wants. The advertising spots should be in another folder. Unique for any user. I want this web player to support: A. Crossfading the tracks between them B. Loading tracks from two folders/sources (music folder and advertising spots folder). It should be playing the tracks from a music folder and when user wants (from options) it should load the advertising spots, that should be in the advertising spots folder to play between music tracks. C. Auto gain or audio limiter. I want this player to give the same volume in all tracks. D. Auto shuffling. Thanx in advance!
