  • Publication number: 20230144494
    Abstract: An audio signal processing device includes a first input terminal which receives an audio signal from a record player, a memory which stores a correction parameter for audio signal processing and characteristic information indicating the characteristic of an audio signal for measurement, a signal processing circuit which performs the audio signal processing on the audio signal received based on the correction parameter, and a microcomputer. The microcomputer measures the sound characteristic of the audio signal received when the audio signal for measurement recorded on a phonograph record for measurement are reproduced, generates the correction parameter based on a result of comparison between the result of the measurement and the characteristic information, and stores, in the memory, setting information and the correction parameter generated, in association with each other, the setting information indicating a setting on the audio signal processing when the measurement is performed.
