摘要
In the present invention, a first frequency analysis unit performs a first frequency analysis on first audio data for each range of a plurality of analysis ranges, and generates first result information indicating the result of the first frequency analysis for each range of the plurality of analysis ranges. A condition determination unit determines an analysis range in consideration of a first audio quality of the first audio data. A noise band detection unit detects a noise band for each range of the plurality of analysis ranges on the basis of the first result information and second result information. A first filter processing unit generates a first filter that filters data of the noise band for each range of the plurality of analysis ranges, and performs first filter processing using the first filter on the first audio data for each range of the plurality of analysis ranges to generate third audio data.
