一、引言在钢琴生产过程中,钢琴音准的调整与检测直接影响钢琴质量。长期以来,因缺乏有效的检测手段,钢琴音准的调整与检测主要凭调音师的听觉和经验进行。既费时费事,又不十分可靠。本文的目的是探讨微型计算机在钢琴音准检测中的应用。钢琴音准的测定问题,实质上是钢琴各个键音的基音检测问题。关于基音检测,在语音信号处理研究中已经提出了许
I. INTRODUCTION In the process of piano production, the adjustment and detection of the piano sound level directly affect the piano quality. For a long time, due to the lack of effective testing methods, the adjustment and detection of piano tunes are mainly based on the sound engineer’s experience and hearing. It is time-consuming, not very reliable. The purpose of this paper is to discuss the application of microcomputer in the piano pitch detection. Piano sound quasi determination of the problem, in essence, is the pitch of the piano key sound detection problems. Pitch detection has been proposed in speech signal processing research
