Abstract :
Each pitch of the normal musical signal corresponds to a fixed frequency. If the singer deviates from this frequency, it will cause “abnormal pitch”. This paper studies the method for correcting the abnormal pitch by using the DSP technology and its realization in high speed processor, the TMS320C50
