Abstract: A device that enables easy, reliably performance of a search at a desired position even in the case of a one-bit digital signal. A control section of a digital signal processing device extracts a one-bit digital signal of a predetermined period from a memory section at a position designated by a jog dial and iteratively outputs the signal to a multi-bit converter. The multi-bit converter converts the one-bit digital signal into a multi-bit signal, and a multiplier subjects the multi-bit signal to fade-in and fade-out processing. A ?? modulator re-converts the thus-processed signal into the one-bit digital signal, outputting the digital signal.
