Measurement device, measurement method, recording medium, and phonograph record

A measurement device included in a record playback system including a record player, the measurement device comprising:

• a processor;
• and
• a memory,
• wherein the processor, by executing a program stored in the memory:
• measures a frequency characteristic of each of a plurality of input signals which are input from the record player to the measurement device when a plurality of test signals for measuring a characteristic of the record playback system are played back by the record player, the plurality of test signals being recorded on a phonograph record, the plurality of input signals corresponding to the plurality of test signals recorded;
• calculates a measurement error between the frequency characteristic of each of the plurality of input signals measured and a predetermined frequency characteristic;
• selects a frequency characteristic of which the measurement error is smallest from among the frequency characteristics of the plurality of input signals, as a measurement result of the record playback system;
• and
• outputs the measurement result selected.
