摘要： A method for processing audio data, comprising providing song identification data identifying a particular song from among a plurality of songs or identifying a particular position within a particular song, loading intermediate data associated with the song identification data from a storage medium or from a remote device. The method also comprises obtaining input audio data representing audio signals of the song as identified by the song identification data. The audio signals comprise a mixture of different musical timbres, including at least a first musical timbre and a second musical timbre different from said first musical timbre. The method comprises combining the input audio data and the intermediate data with one another to obtain output audio data. The audio data represent audio signals of the first musical timbre separated from the second musical timbre.

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： Audio generation method, server and storage medium are provided. The method includes obtaining a comparison audio, and performing a theme extraction on the comparison audio to obtain a comparison note sequence, the comparison note sequence comprising comparison note positions, comparison note pitches, and a comparison note duration; obtaining an original audio matching with the comparison audio via audio retrieval, and obtaining an original note sequence corresponding to the original audio by performing a theme extraction on the original audio, the original note sequence comprising original note positions, original note pitches, and an original note duration; calculating theme distances between fragments of the comparison audio and fragments of the original audio according to the comparison note sequence and the original note sequence; and generating an audio by capturing a fragment that is of the original audio and that satisfies the smallest theme distance.

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.
