Piano Doctor is a Music app by Jongseung Park. This app analyzes piano sounds. It detects the frequencies in the sound and estimates how far the sound's tone is away from the target tone.

Yes. We provide some of the safest Apk download mirrors for getting the Piano Doctor apk.
1. In the case where users want to see the frequency responses in a specific harmonic band, users can use the harmonic selector buttons located near the harmonic gauge.
2. Harmonic bands are defined as the frequency bands where the frequencies are integer multiples of the fundamental band.
3. In doing so, this app measures a band of frequencies called the target frequency band, which is defined as the frequency range between -50 cents and +50 cents centered at the target frequency.
4. The difference between the peak frequency in the target band and the target frequency is displayed in the gauge in the user interface.
5. A separate gauge is provided to show the frequency offset calculated from the harmonic band.
6. While gauges are showing only peak frequencies, spectrums viewers are showing frequency spreads in two-dimensional shapes.
7. With the self-generated tone on and the speaker at the proper volume, at least one of the gauges should report the precise frequency that is being generated.
8. Then, this app identifies the peak frequency where the sound has the biggest power in the band.
9. This app measures frequencies in the 6 harmonic bands (from the second to the seventh) and selects the best one automatically if the "AUTO" button is selected in the harmonic selector.
10. The frequency estimations are based on 131,072 point Fourier transforms and such long Fourier transforms provides very stable gauge readings.
11. In addition to the gauges showing the frequency offsets, this app provides two spectrum viewers.
