Latest Patents

One of his latest patents is titled "Device, method, and medium for generating audio fingerprint and retrieving audio data." This invention provides a comprehensive solution for generating an audio fingerprint and retrieving audio data. The device includes a coefficient extracting section that partially decodes audio data in a compression area and extracts MDCT (Modified Discrete Cosine Transform) coefficients. It also features a coefficient selecting section that identifies an MDCT coefficient robust to noise from the extracted coefficients. Additionally, a modulation spectrum generating section transforms the selected MDCT coefficient using a Fourier transform method, generating a modulation spectrum. Finally, a bit conversion section quantizes the generated modulation spectrum to create an audio fingerprint. This technology allows for accurate and rapid retrieval of audio data recorded in various environments, making it applicable to MP3 applications and classification of audio data, such as music moods and genres.

Another notable patent is the "Method, medium, and system for music retrieval using modulation spectrum." This invention focuses on an audio information retrieval method that can quickly retrieve audio information, even in noisy environments. It involves extracting a modulation spectrum that is robust against noise, converting features of the extracted modulation spectrum into hash bits, and utilizing a hash table for efficient retrieval. The method includes extracting a modulation spectrum from audio data in a compressed domain, converting it into fingerprint bits, and arranging these bits in a hash table. This innovative approach significantly enhances the speed and accuracy of audio information retrieval.
