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.
Claims27
An apparatus for signal processing, comprising:
- a position encoder for generating position data associated with a spatial relationship between an analog signal source from which an analog audio waveform is generable and an analog signal source assembly for generating the analog audio waveform;
- and
- a signal processing unit for sampling the analog audio waveform at a rate corresponding to the position data and for outputting an external digital signal for controlling an additional media source, wherein the position data controls the outputting of the external digital signal such that portions of the external digital signal corresponding to portions of the analog audio waveform associated with the position data are output in response to the position data to control the additional media source in correspondence with the analog audio waveform.
A method of processing analog and digital waveforms, comprising:
- generating an analog audio waveform from an analog signal source;
- generating position data specifying locations on and distances traveled by an analog signal source assembly along the analog signal source and encoding the position data to generate data related to portions of the generated analog audio waveform;
- providing a digital waveform, wherein providing the digital waveform and generating the analog audio waveform are independently performed;
- and
- outputting portions of the digital waveform selected based on the position data wherein the selected portions of the digital waveform correspond to the portions of the analog audio waveform associated with the position data and control an additional media source.
A method of processing analog and digital waveforms, comprising:
- generating an analog waveform from an analog signal source;

- storing a waveform map including at least two correspondences between position data and a sampling of one of the portions of the generated analog waveform related to the position data;
- providing a digital waveform, wherein providing the digital waveform and generating the analog waveform are independently performed;
- generating a synchronization map including at least two correspondences between portions of the digital waveform that correspond to portions of the generated analog waveform stored in the waveform map, and the position data corresponding to the portions of the generated analog waveform data from the waveform map;
- and
- outputting portions of the digital waveform selected based on the position data wherein the selected portions of the digital waveform correspond to portions of the analog waveform associated with the position data using the synchronization map.
