Claims

1. Apparatus for signal processing in conjunction with a digital audio source, said apparatus comprising:

a record player with a turntable and an arm;

a pick-up element disposed on said arm for playing a conventional record; and

a digital filter fed by said pick-up element comprising a circuit for detecting and following a carrier frequency and a demodulation circuit for demodulating a time-code signal that is modulated on the carrier frequency in the audible range between 20 and 20,000 Hz.

2. Apparatus according to claim 1, wherein said apparatus additionally comprises a detection device for determining phase difference between the time-code signal demodulated from left and right channel signals, respectively.

3. Apparatus according to claim 1, wherein the time-code signal controls the digital audio source.

4. Apparatus according to claim 3, wherein said apparatus additionally comprises a digital audio buffer under control of the time-code signal, and wherein the digital audio buffer is connected to a digital output filter which feeds a signal output which is selected from the group consisting of a digital electric output socket, a digital optic signal output, and a digital-to-analog converter.

5. Apparatus according to claim 4, wherein said apparatus additionally comprises a control logic device fed by the time-code signal and determining a velocity signal being a measure for speed of change of the time-code signal, and wherein the digital output filter is controlled by said control logic device.
