It is the sound effect when collect hearts that is not optimal ?

I think the sounds in themselves were good, but their volume is way compared to the rest. The sound effects also start with a delay, I suspect that your sound files don't start exactly at 0.00s? FYI you can fix all of those things in godot, without having to meddle with the sound files:
