Abstract
An apparatus processes an analog audio signal having been stored in a recording medium in a recording order and being reproduced therefrom in a reverse order of the recording order and at a speed .alpha. (.alpha..gtoreq.1) times higher than a recording speed to the recording medium. The analog signal is converted to digital audio signals and written in a memory having head and final addresses. The digital audio signals read from the memory are converted to an output analog audio signal. A controller controlling writing and reading the digital audio signals to and from the memory has a read address controller for controlling read addresses of the memory such that the read addresses repeatedly reciprocate between the head and final addresses. The controller controls the writing such that, if .alpha.>1, the writing starts in sequence from the head or final address when the read address reaches in the vicinity of an address which advances by (.alpha.-1) / .alpha. of all the addresses after returned at the head or final address, whereas if .alpha.=1 the writing starts in sequence from the head or final address immediately after the read address returning at the head or final address.
