I have this little radio board but when power is applied it makes scratches and pops for half a second before it gets quiet. I wonder if there is proven way of muting input of the amplifier and slowly fading it in by, I dunno, using a transistor and a capacitor with some resistor to slowly close it,…

So, I had to abandon the idea of using class D amplifier all together. They create too much RF interference and I needed it for FM radio project. Even though I managed get rid of annoying crackle by using different chip, it was only letting me to tune to 3 out of 26 stations. In the end I found TDA1…
