Far greater high partial information, spectral purity, and tuning accuracy is achieved with the the sensor vs a mic. This indeed affects the tuning accuracy measurement achievable in an ETD app. The PianoSens sensor captures far more energy in the higher partials or harmonics. This results in a greater signal-to-noise of the waveform, and therefore more accuracy in the frequencies. In this example, the difference is as much as 0.6 cents but on some notes it can be greater than 1 cent.

| Using the PianoSens sensor we are able to get more spectrally pure information that affects the tuning accuracy measurement achievable in an ETD app. The sensor captures far more energy in the higher partials or harmonics. This results in a greater signal-to-noise of the waveform, and therefore more accuracy in the frequencies. |
