PROBLEM TO BE SOLVED: To provide a signal processing apparatus such as an audio signal processing apparatus capable of efficient processing even on the occurrence of a defect or a biased operating rate or load in part of signal processing processors such as a part of DSPs. SOLUTION: A signal received via a circuit (not shown) is given to an A before-processing area 135 of a second shared memory 1082 which is subjected to the processing by an A processing DSP group 121, the processed signal is transferred to an after-A processing before B processing area 136, which is subjected to processing by a B processing DSP group 122 this time. The signal is similarly processed in this way. Loads of DSPs 105 being components of the A processing DSP group 121 to a C processing DSP group 123 are respectively detected, an idle DSP group 124 D in a D processing DSP group 124 is graded up to A standby group to C standby group 124C depending on the detected load and added to a corresponding processing DSP group when the loads furthermore get heavy.
