AUDIO SIGNAL PROCESSOR WITH PITCH AND EFFECT CONTROL

摘要

An audio processing apparatus is constructed for generating an auxiliary audio signal based on an original audio signal and mixing the auxiliary audio signal to the original audio signal. In the apparatus, a control section designates a pitch of the auxiliary audio signal. A processing section processes the original audio signal under control of the control section to generate the auxiliary audio signal having the designated pitch, and applies a first effect to the generated auxiliary audio signal. An effector section applies a second effect different from the first effect to the original audio signal. An output section outputs the original audio signal applied with the second effect concurrently with the auxiliary audio signal applied with the first effect. The control section may control the processing section to alter the first effect dependently on a difference between a pitch of the original audio signal and the designated pitch of the auxiliary audio signal.
