Abstract

A technology is provided that can obtain two audio data with reduced noise, in a system including independent recording devices. A first frequency analyzer performs first frequency analysis on first audio data for each analysis range and generates first result information indicating the result of the first frequency analysis for each analysis range. A condition determinator determines the analysis range based on a first audio quality of the first audio data. A noise band detector detects a noise band for each analysis range based on the first result information and second result information. A first filter processor generates a first filter for filtering data of a noise band for each analysis range, applies a first filter process by the first filter on first audio data for each analysis range, and generates third audio data.
