I know about the solutions in the native wrappers. In this case, I'm actually not looking for polyphony, but simply no delays in audio playing in browsers on mobile phones, or at least in iOS safari.
It would be nice to have Pode's solution part of your C2 build process.
Pode, you available for hire? I'm on a very tight deadline of tomorrow. You want to help me with your audio sprites solution? Email me at jamesmrz@faceyspacey.com. I PMed you, but I'm not sure you saw it.
