    摘要： The present invention relates to an AGC circuit, a AGC circuit gain control method, and a program for the AGC circuit gain control method, and may be applied to IC recorders, for example, as a portable recording/reproducing device, in order to ameliorate problems of listening to talk, music and the like during playback from IC recorders. In the invention, a signal level L1cyc is detected in units of the period of an input signal, and a recovery time constant r is switched on the basis of a decision as to the signal level L1cyc based on an average shift Lavg of the signal level L1cyc.

    摘要： A portable type recording and reproducing device including recording means for converting sound information obtained by collecting external sound to files in message units and recording the files on a predetermined recording medium, and recording image information obtained by photographing an outside on the recording medium in association with a corresponding file of sound information in response to a predetermined first external operation, display means for displaying images based on image information associated with respective files of sound information, and reproducing means for reproducing a file of sound information associated with an image selected by a predetermined second external operation among the images displayed by the display means. The recording means creates an image managing file for associating the sound information with each piece of image information, and the reproducing means reproduces the file of the sound information associated with the image selected by the predetermined second external operation among the images displayed by the display means on a basis of the image managing file.

    摘要： A software program of a flash memory loaded into an IC recorder is read and executed by a PC connected to the IC recorder via an external interface and an input-and-output end, so that an information signal, such as audio data held by the PC, is transferred from the PC to the flash memory. Management information about the information signal that is transferred and stored in the flash memory is generated by the software program executed by the PC and stored in the flash memory, so that the IC recorder can use the management information.
