  2. Music information retrieval - Wikipedia

    en.wikipedia.org/wiki/Music_information_retrieval

    Music information retrieval (MIR) is the interdisciplinary science of retrieving information from music. Those involved in MIR may have a background in academic musicology , psychoacoustics , psychology , signal processing , informatics , machine learning , optical music recognition , computational intelligence , or some combination of these.

  3. Optical music recognition - Wikipedia

    en.wikipedia.org/wiki/Optical_music_recognition

    Music information retrieval (MIR) is the broader problem of retrieving music information from media including music scores and audio. Optical character recognition (OCR) is the recognition of text which can be applied to document retrieval, analogously to OMR and MIR. However, a complete OMR system must faithfully represent text that is present ...

  4. Harmonic pitch class profiles - Wikipedia

    en.wikipedia.org/wiki/Harmonic_pitch_class_profiles

    By processing musical signals, software can identify HPCP features and use them to estimate the key of a piece, [2] to measure similarity between two musical pieces (cover version identification), [3] to perform content-based audio retrieval (audio matching), [4] to extract the musical structure (audio structure analysis), [5] and to classify ...

  5. Computational musicology - Wikipedia

    en.wikipedia.org/wiki/Computational_musicology

    Computational musicology includes any disciplines that use computation in order to study music. It includes sub-disciplines such as mathematical music theory, computer music, systematic musicology, music information retrieval, digital musicology, sound and music computing, and music informatics. [2]

  6. Music informatics - Wikipedia

    en.wikipedia.org/wiki/Music_informatics

    [1] [2] Other music informatics research topics include computational music modeling (symbolic, distributed, etc.), [2] computational music analysis, [2] optical music recognition, [2] digital audio editors, online music search engines, music information retrieval and cognitive issues in music. Because music informatics is an emerging ...

  7. OpenMusic - Wikipedia

    en.wikipedia.org/wiki/OpenMusic

    A substantial body of specialized libraries has been contributed by users, which extends OpenMusic's functionality into such areas as constraint programming, aleatoric composition, spectral music, minimalist music, music theory, fractals, music information retrieval, sound synthesis etc.

  8. Pitch detection algorithm - Wikipedia

    en.wikipedia.org/wiki/Pitch_detection_algorithm

    Frequency domain, polyphonic detection is possible, usually utilizing the periodogram to convert the signal to an estimate of the frequency spectrum [4].This requires more processing power as the desired accuracy increases, although the well-known efficiency of the FFT, a key part of the periodogram algorithm, makes it suitably efficient for many purposes.

  9. Multimedia information retrieval - Wikipedia

    en.wikipedia.org/wiki/Multimedia_Information...

    Multimedia information retrieval (MMIR or MIR) is a research discipline of computer science that aims at extracting semantic information from multimedia data sources. [1] [failed verification] Data sources include directly perceivable media such as audio, image and video, indirectly perceivable sources such as text, semantic descriptions, [2] biosignals as well as not perceivable sources such ...
