チ変換器。[Claims for Utility Model Registration] (1) A pitch converter that can pitch-convert an input audio signal based on a conversion rate specified on the operation unit and output audio with a pitch different from that of the input audio signal. In the converter, the conversion rate is determined in the operation section according to the on/off state of one or more operation keys, and the operation keys are arranged near the holding section of the pitch converter. A pitch converter characterized in that a user can freely set a conversion rate while performing a pitch conversion operation. (2) The utility model registered in claim (1) is characterized in that the operation key is configured with a variable volume, and the pitch conversion rate is determined based on the operated volume value. Pitch converter as described.
