ABSTRACT:
An apparatus including sensors that aid in the location of a stylus within the groove of a rotating record. The location of the stylus corresponds to a portion of an audio waveform present at a unique location within the groove. Using the correspondence between the location of the stylus and the portion of the audio waveform, an external digital source may be synchronized with an analog waveform. A high speed digital data path connects a control unit including a turntable platter to signal processing unit. Software in the signal processing unit synchronizes the analog waveform and digital signals from the external digital source.
