Abstract
Recording and reproducing apparatus is disclosed wherein stereo signal components which include a monaural signal component are supplied to a signal processing circuit. The signal processing circuit replaces the supplied monaural signal component with a further monaural signal component. The thus processed stereo signal components, including the further monaural signal component, are supplied to a first recording head for recording on a medium. The supplied stereo signal components including the supplied monaural signal component are coupled to a second recording head for recording on the medium. The recorded stereo signal components including the further monaural signal component and the recorded stereo signal components including the supplied monaural signal component are reproduced from the medium and sounds corresponding to the reproduced signals are generated. The reproduced sounds thus include the stereo signal components, the further monaural signal component and the supplied monaural signal component so that both monaural signal components can be audibly compared. In one embodiment, reproduction of the supplied monaural signal component can be supressed, whereby the generated sounds represent the further monaural signal component in combination with the supplied stereo components.
