ABSTRACT:
A recording device obtains audio signals by plural microphones and records the audio signals on a recording medium. The device includes plural incorporated microphones for obtaining the audio signals; correction circuits for changing characteristics by correction parameters for the incorporated microphones, for correcting characteristics of the audio signals obtained by the incorporated microphones to a reference characteristic, and for outputting the corrected audio signals; and a recording device for recording the corrected audio signals output from the circuits on the recording medium. When an audio signal obtained by an external microphone is input to the correction circuits and recorded on the recording medium instead of all the audio signals or a part of the audio signals obtained by the plural incorporated microphones, the characteristic of a corresponding correction circuit is set by a correction parameter for the external microphone, the parameter is obtained from the external microphone, the audio signal obtained by the external microphone is corrected to the reference characteristic to produce a different corrected audio signal, and the different corrected audio signal is output.
