Abstract
Method and apparatus for signal processing for controlling a digital audio source may include retrieving a time code signal from a rotating recording medium. The time code signal may be a sum of a binary signal and a sinusoidal pilot signal in the audible range, and the binary signal has a symbol frequency less than a frequency of the pilot signal. The time code signal may be filtered to recover the pilot signal and the binary signal. An estimated speed of rotation of the recording medium may be determined from a recovered pilot signal, and an estimated position may be determined from a recovered binary signal, for controlling the digital audio source.
