Abstract
An apparatus is provided for evaluating the tonal characteristics of an object with respect to a nominal tone which comprises a striker for causing the object to generate an audio signal and a microphone for inputting the audio signal. A reference signal generator generates plural reference signals in accordance with the nominal tone, and those signals are mixed with the audio signal by a mixing circuit. The accuracy of the audio signal with respect to the nominal tone is evaluated in accordance with the audio signal mixed by the mixing circuit.
