A audio mixer player that allows a user to press "play", start all tracks at the same time, and adjust individual track volume levels on the fly. There are some old players out there that basically do this, but they are all flash based and I really need one that plays on mobile devices. I've seen some html 5 players that get close, but still don't do what I need. Here are some linked examples: This is more or less what I want but is flash: /windows/audio-mixer-player-48265.html Another one: /2009/08/12/online-audio-mixer/ This is the closest thing I've found in HTML5: /html5/html5audio1.htm The HTML5 example is not what I need, but it's the closest I've seen that is not flash. Also, depending on the difficulty of creating this, two other features that would be really helpful would be: -a looping function where the customer could select an "A" point and a "B" point to just keep on repeating an area of a song. -a tempo function that could slow down the recording without altering the pitch Desired Skills: HTML5 Keywords: Other IT & Programming, HTML5
