There is provided a signal processing apparatus that obtains a speech signal with sufficiently reduced wind noise. The signal processing apparatus includes a main microphone that is provided so as to be readily influenced by movement of air outside the signal processing apparatus, a sub microphone that is provided so as to be hardly influenced by movement of air outside the signal processing apparatus, a determiner that determines, based on a strength of a main speech signal output from the main microphone, whether the main speech signal includes a predetermined amount of wind noise, and a selector that receives the main speech signal and a sub speech signal output from the sub microphone, executes, if it is determined that the main speech signal includes the predetermined amount of wind noise, selection processing for outputting the sub speech signal, and executes, if it is determined that the main speech signal includes no predetermined amount of wind noise, selection processing for outputting the main speech signal.
