Abstract

The present invention provides a piano tuning system. The piano tuning system is applied to an electronic device. The electronic device comprises a microphone and a display screen; the display screenis fixed through a bracket; and the bracket is connected with a piano, the system comprises a display module, a storage module, an audio collection module, an audio coding module, a waveform comparison module and a calculation output module. The invention provides a piano tuning method. The method includes the following steps that: the system is started, a spectrum display range and a standard audio source file required for calibration are selected; the audio collection module receives sound signals sent by piano strings and sends the sound signals to the audio encoding module; the audio encoding module performs spectrum analysis on the received sound signals so as to obtain a sound signal spectrum and draws a corresponding adjustment peak curve on the basis of preset fixed frequency pointpeaks; and a standard sound source file spectrum is obtained, and a corresponding standard rhythm peak curve is drawn on the basis of preset fixed frequency point peaks is acquired.
