Yes, until we build a Class D amplifier with a easy to handle via Software DSP ADAU1401, but Analog Devices did not support class D PWM audio output. So we whant to try STM32 for a Class D active speaker. And we see that there is no easy to handle so...

Do you have any sources for this easy to find principle?There are also libraries for the Cube IDE which you can implement DSP functions.Are also example codes available until today?
