摘要： A method distinguishes components of a signal by processing the signal to estimate a set of analysis features, wherein each analysis feature defines an element of the signal and has feature values that represent parts of the signal, processing the signal to estimate input features of the signal, and processing the input features using a deep neural network to assign an associative descriptor to each element of the signal, wherein a degree of similarity between the associative descriptors of different elements is related to a degree to which the parts of the signal represented by the elements belong to a single component of the signal. The similarities between associative descriptors are processed to estimate correspondences between the elements of the signal and the components in the signal. Then, the signal is processed using the correspondences to distinguish component parts of the signal.

摘要： A system and method for conforming an audio input to a musical key. Audio input is received and the musical key is determined. Sequentially for each consecutive note, a pitch value for each note and an interval between each preceding and subsequent note is determined; alternative subsequent notes based on the musical key and the pitch value of the subsequent note are determined; each interval between each alternative subsequent note and each respective note of the alternative subsequent notes corresponding to the preceding note is scored based on the interval between the preceding note and the subsequent note of the audio input; and a best interval is selected for each alternative subsequent note. A best-match note is selected for each note of the audio input based on the best intervals of all the notes, and each audio input note is conformed to a frequency of the best-match note.

摘要： A system, method, and computer readable storage medium generates an audio fingerprint for an input audio clip that is robust to differences in key, instrumentation, and other performance variations. The audio fingerprint comprises a sequence of intervalgrams that represent a melody in an audio clip according pitch intervals between different time points in the audio clip. The fingerprint for an input audio clip can be compared to a set of reference fingerprints in a reference database to determine a matching reference audio clip.

摘要： A data processing apparatus acquires a waveform data set from a waveform DB where waveform data sets are stored in association with tag data for classifying the waveform data sets, analyzes a sound waveform signal indicated by the acquired waveform data set to thereby identify a period of the sound waveform signal, having a predetermined feature, as a waveform signal of a sound material, and calculates a feature amount by analyzing the sound waveform signal of a sound material. Then, the data processing apparatus registers, into a sound material DB, identification data indicative of the sound waveform signal of the sound material, feature amount data indicative of the calculated feature amount and the tag data corresponding to the acquired waveform data set in association with one another. The registered tag data can be used for searching for a desired sound material from the sound material database.

摘要： The present document relates to methods and systems for estimating the tempo of a media signal, such as audio or combined video/audio signal. In particular, the document relates to the estimation of tempo perceived by human listeners, as well as to methods and systems for tempo estimation at scalable computational complexity. A method and system for extracting tempo information of an audio signal from an encoded bit-stream of the audio signal comprising spectral band replication data is described. The method comprises the steps of determining a payload quantity associated with the amount of spectral band replication data comprised in the encoded bit-stream for a time interval of the audio signal; repeating the determining step for successive time intervals of the encoded bit-stream of the audio signal, thereby determining a sequence of payload quantities; identifying a periodicity in the sequence of payload quantities; and extracting tempo information of the audio signal from the identified periodicity.
