Float denormal issue in JavaScript processor node in Web Audio API (3)

To see the problem, here is a piano physical model in C++ compiled in asm.js using emcsripten. A single string is then duplicated (for "bug" demonstration purpose) 16 times, so 16 strings are computed all the time.


Chrome CPU  here ==> 36 %

Hit the "gate" button to play a same note on all 16 string, wait some seconds, CPU raise to 100%

Same issue with Firefox and Safari WebKit.
