Measurement of the resonance curve (Acoustics)
Dear @solid,

thank you for the wonderful experiment. I tried as acoustic resonator and it worked perfectly. Both, the sweep option and the FFT.
Then i thought, this could be wonderful for High-/Lowpassfilter with RC. I built one with C=100nF and R=1000Ω.
I can measure the damping (see attached) figure with an oscilloscope, but didn't suceeded with an audio option.
My idea was to use a 3.5 mm 4-conductor and use and audio chanel R and the microphone pin AUX.
But no success. Sometimes it was misinterpreted by the phone as signal to reduce the volume.

Have anyone an idea?
