Abstract: Disclosed is a signal processing apparatus including a surrounding sound signal acquisition unit, a NC (Noise Canceling) signal generation part, a cooped-up feeling elimination signal generation part, and an addition part. The surrounding sound signal acquisition unit is configured to collect a surrounding sound to generate a surrounding sound signal. The NC signal generation part is configured to generate a noise canceling signal from the surrounding sound signal. The cooped-up feeling elimination signal generation part is configured to generate a cooped-up feeling elimination signal from the surrounding sound signal. The addition part is configured to add together the generated noise canceling signal and the cooped-up feeling elimination signal at a prescribed ratio.

Abstract: The present disclosure relates to an information processing apparatus and method capable of performing compensation to achieve a standard sound regardless of a recording environment. The microphone picks up sound from a sound source and inputs the sound to a recording apparatus as an analog audio signal. The recording apparatus is an apparatus that performs binaural recording and generates an audio file of a sound obtained by binaural recording. The recording apparatus adds metadata related to a recording environment of binaural content to the audio file generated by binaural recording and transmits the file with the metadata to a reproducing apparatus. The present disclosure is applicable to a recording/reproducing system that performs binaural recording and reproduction of the sound, for example.
