Audio processing apparatus, audio processing method and imaging apparatus

摘要

An audio processing apparatus including: an obtaining unit configured to obtain audio signals; and a processor configured to process the audio signals, wherein if it is not determined that the audio signals contain an abnormal value, the processor calculates a next sample value based on a predetermined number of sample values of the audio signals obtained by the obtaining unit, and wherein if it is determined that the audio signals contain an abnormal value, the processor uses the calculated next sample value so as to calculate a further next sample value.

1. An audio processing apparatus comprising:
an obtaining unit configured to obtain an audio signal; and a processor configured to process the audio signal and to reduce noise in the audio signal, wherein if it is not determined that the audio signal contains an abnormal value, the processor obtains prediction data based on a predetermined number of samples of the audio signal obtained by the obtaining unit and updates parameter for obtaining the prediction data such that a difference between the prediction data and the audio signal obtained by the obtaining unit becomes smaller, and wherein if it is determined that the audio signal contains an abnormal value, the processor obtains next prediction data by using the prediction data which has already been obtained and reduces noise in the audio signal by using the next prediction data.
