New and Improved DFPlayer Mini Library!!

I use a sound bank form fx-saberoos project.
The file are wav 16 bit mono.
Every file is clean from clicks, dc offset 0 and start at cross to 0.
But when the hum sound is interupted by a swing sound sometimes I hear a click at the baginning of the swing.
There is not any click inside files.
There is other things that i can do?
