Abstract:
An audio codec having multiple selectable processing paths comprising:a first processing path comprising:an analog input mixer for mixing analog data streams received at a plurality of analog inputs into an mixed analog data stream;an analog to digital converter for converting said mixed analog data stream into a digital data stream;a digital mixer for mixing data from a digital input with said digital data stream to produce a mixed digital data stream;a digital to analog converter for converting said mixed digital data stream into a second analog stream;an analog output mixer for mixing said second analog stream with analog data received from a second analog input, to produce an analog output stream; andat least one output for transmitting said analog output stream to an external device; anda second processing path comprising:an multiplexer for selecting a data stream from among said analog data streams received at said plurality of analog inputs and said analog output stream;an analog to digital converter for converting said data stream selected by said multiplexer into digital form; andan output port for transmitting said selected data stream in digital form to an external device.
