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.

Abstract: An amplification device is configured to operate such that when a first amplifier function is switched to a second amplifier function (S13) and then the second amplifier function is switched to the first amplifier function (S15) and at this time a state of an operating member is a state corresponding to a second sound volume larger than a first sound volume that was output right before switching from the first amplifier function to the second amplifier function (S16), the amplification device causes the state of the operating member to change to a state corresponding to a third sound volume smaller than the second sound volume (S17), and controls an amplifying operation of a signal processing circuit to cause it to output the third sound volume (S18).

Abstract: At a startup of an audio recording and playback apparatus and after executing a function other than a recording function, a controller reads out a recording program stored in the nonvolatile memory, stores the recording program into the RAM, and puts the audio recording and playback apparatus into a stop state. Further, when a recording key is turned on, the controller executes the recording program stored in the RAM.

Abstract: A battery-operated recording medium controller monitors the ID of a replayed melody and when a replay ID comparing section (A126) makes a decision that a melody of the same ID as the previous one is replayed, a section (A127) for judging necessity of auxiliary information designates an auxiliary information access control section not to acquire auxiliary information (ID3 tag) again from a disc but to reuse auxiliary information stored in an auxiliary information storing section A. Consequently, the number of times of accessing the recording medium is decreased, and when the auxiliary information added to reproduction data like the ID3 tag of an MP3 is acquired, moving distance of an optical pickup is decreased and current consumption can be reduced.

Abstract: Provided is a recording medium playback device intended to achieve a reduction in power consumption by stopping disk rotation during a period in which no content data is being read, while improving playability and responsiveness to external key inputs or the like. A system control section 106 instructs a servo control section 105 to stop rotating a spindle motor 102 after an optical pickup 103 completely reads the content data that is being reproduced, and to forcibly rotate the spindle motor 102 in order to start reading the next content data to be reproduced when the remaining amount of data accumulated in a buffer memory 113 falls to a threshold n or lower, the threshold n being calculated based on (a) a stabilization time of the spindle motor 102, (b) a moving time of the optical pickup 103, and (c) a speed at which data is read from the buffer memory 113.
