APPARATUS AND METHOD FOR MEASURING QUALITY OF AUDIO

摘要

Disclosed are a device and a method for measuring an audio quality using fingerprints and feeling feature information. The device for measuring an audio quality according to the present invention comprises a distortion signal generation unit for generating a plurality of distortion signals according to the predetermined distortion reference for an audio; an extraction unit for extracting fingerprints and feeling feature information corresponding to the audio and the distortion signals; a distortion degree measurement unit for measuring a fingerprint distance difference between the fingerprints corresponding to the audio and the fingerprints corresponding to the distortion signals and an AV distance difference between the feeling feature information corresponding to the audio and the feeling feature information corresponding to the distortion signals; a distortion function generation unit for generating a fingerprint distortion function and an AV distortion function based on the respective distributions corresponding to the fingerprint distance difference and the AV distance difference; and a search and measurement unit for extracting the fingerprints and the feeling feature information from an optional inquiry audio and comparing the extracted results with the fingerprint distortion function or the AV distortion function to measure an audio quality.
