Interesting ! you can do even frequency modulation by varying the IR frequency with a transistor from pin 3 to GND. The output filter passes the low frequencies more and HF less. :05.18-flustered:

I'm more interested in class AB than class D

Class D is interesting too, you can get big power easily and the sound quality is still very good !

at least I know ir2153 can be a class d amplifier , I tried simulation but I can't make it better
maybe Norazmi has a better design

This is good enough for class D. Can I get from you the IR2153, irf640 and lm311 ltspice symbols ?
