ABSTRACT:
A sound signal recorded in a memory synchronously with a low-frequency clock signal is read out with the low-frequency clock signal to reproduce a normal sound, thereby enabling checking of the sound signal recorded in the memory. For recording in a recording medium, the sound signal is read out with a high-frequency clock signal to effect time axis compression. By designating an address to start writing, a sound signal can be written starting with any address thereby facilitating editing. An analog sound signal previously recorded on a magnetic recording medium is time axis expanded by a time axis expansion device and then outputted from a sound output device, and the analog sound signal is hybridized with another analog sound signal inputted from a microphone, time axis compressed by a time axis conversion device, and recorded on the magnetic recording device.
