Yes, First, I'd use _ctl() to modify the setting of sample rate, and Second,
I tried using 8kHz sample rate to compare and the resonance and explosion
does not appear. I found because of notch_radius will sharp the sound and
let the resonance not to be produced. The frequency around the pitch G3

Try using 8 kHz just to compare. Other sampling rates are less tested
and you need to specify the sampling rate the the _ctl() call.
