| Abstract: | This article introduces the principle of three-level center clipping autocorrelation analysis method and the difficulties in applying this method to detect the sound accuracy of piano keys.Improvements are introduced and a detection system is designed for tuning pianos.This detection system can automatically test whether or not the piano is in a perfect tune after being preliminary tuned manually and sound deviations of each key are tabulated.This paper provides quantificational measurement for piano specification. |
