Latest Patents
One of Bob Coover's latest patents involves methods and apparatus for audio identification during a performance. This innovative apparatus includes at least one memory and at least one processor that transforms a segment of audio into a log-frequency spectrogram using a constant Q transform. The process utilizes a logarithmic frequency resolution to convert the log-frequency spectrogram into a binary image. Each pixel of this binary image corresponds to a time frame and frequency channel pair, with each frequency channel representing a corresponding quarter tone frequency channel in a range from C3 to C8. The apparatus generates a matrix product of the binary image and a plurality of reference fingerprints, normalizes this matrix product to form a similarity matrix, and selects an alignment of a line in the similarity matrix that intersects one or more bins with the largest calculated Hamming similarities. Finally, it selects a reference fingerprint based on this alignment.
