摘要： An audio identification method and apparatus are disclosed within the technical field of audio processing technology. The audio identification solution includes obtaining an original pitch sequence of a to-be-identified audio, where the original pitch sequence is used to indicate a frequency of the to-be-identified audio at each time point. The audio identification solution further includes dividing the original pitch sequence into a plurality of pitch sub-sequences, respectively identifying the original pitch sequence and the plurality of pitch sub-sequences, and combining the identification results. In doing so, the audio identification solution obtains a final identification result by dividing a long pitch sequence into a plurality of short pitch sequences, thus respectively identifying the long pitch sequence and the plurality of short pitch sequences, and combining identification results.

摘要： Captured vocals may be automatically transformed using advanced digital signal processing techniques that provide captivating applications, and even purpose-built devices, in which mere novice user-musicians may generate, audibly render and share musical performances. In some cases, the automated transformations allow spoken vocals to be segmented, arranged, temporally aligned with a target rhythm, meter or accompanying backing tracks and pitch corrected in accord with a score or note sequence. Speech-to-song music applications are one such example. In some cases, spoken vocals may be transformed in accord with musical genres such as rap using automated segmentation and temporal alignment techniques, often without pitch correction. Such applications, which may employ different signal processing and different automated transformations, may nonetheless be understood as speech-to-rap variations on the theme.

摘要： In an example context of identifying live audio, an audio processor machine accesses audio data that represents a query sound and creates a spectrogram from the audio data. Each segment of the spectrogram represents a different time slice in the query sound. For each time slice, the audio processor machine determines one or more dominant frequencies and an aggregate energy value that represents a combination of all the energy for that dominant frequency and its harmonics. The machine creates a harmonogram by representing these aggregate energy values at these dominant frequencies in each time slice. The harmonogram thus may represent the strongest harmonic components within the query sound. The machine can identify the query sound by comparing its harmonogram to other harmonograms of other sounds and may respond to a user's submission of the query sound by providing an identifier of the query sound to the user.

摘要： A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

摘要： A beat information corrector acquires beat position information including information regarding a point of time when a beat is reproduced, acquires a tempo value indicating a number of beats per unit time in a music piece, and corrects the beat position information of the music piece so that the tempo value of the music piece be a same value as the reference value. A correlation value calculator calculates a correlation value, which indicates a degree of correlation of beat position information between respective music pieces among a plurality of the music pieces, based on the corrected beat position information. A music piece order determiner determines a music piece order as a reproduction order of music pieces, which are to be reproduced successively, so that a product or total sum of the correlation values between the music pieces be at a maximum or an approximate solution thereof.
