Patent ID: 7197299

Claim:
An analog signal recording and playback system comprising: an integrated circuit having: first and second analog inputs configured to receive first and second separate analog input signals; first and second analog outputs configured to provide first and second separate analog output signals; a storage array configured to store analog signals and having record and playback capabilities; an interface configured to receive digital control information and control the read and write capability of the storage array and the selective coupling of the first and second analog inputs, the first and second analog outputs and the storage array to select any one of the following: a) couple the first analog input signal received by the first analog input to the first analog output to provide the first analog output signal, and couple the second analog input signal received by the second analog input to the second analog output to provide the second analog output signal; b) couple the first analog input signal received by the first analog input to the storage array and to place the storage array in the record mode; c) couple the storage array to the first analog output to provide the first analog output signal and to place the storage array in the playback mode; d) couple the first analog input signal received by the first analog input to the first analog output to provide the first analog output signal, couple the second analog input signal received by the second analog input to the second analog output to provide the second analog output signal, couple a combination of the first analog input signal from the first analog input and the second analog input signal from the second analog input to the storage array, and place the storage array in the record mode; e) place the storage array in the playback mode, couple a combination of a playback signal from the storage array and the first analog input signal from the first analog input to the first analog output to provide the first analog output signal, and couple a combination of a playback signal from the storage array and the second analog input signal from the second analog input to the second analog output to provide the second analog output signal; f) couple the first analog input signal from the first analog input to the first analog output to provide the first analog output signal, place the storage array in the playback mode, and couple a combination of a playback signal from the storage array and the second analog input signal from the second analog input to the second analog output to provide the second analog output signal; and, g) couple the second analog input signal from the second analog input to the second analog output to provide the second analog output signal.
