  2. Mel-frequency cepstrum - Wikipedia

    en.wikipedia.org/wiki/Mel-frequency_cepstrum

    MFCCs are commonly used as features in speech recognition [7] systems, such as the systems which can automatically recognize numbers spoken into a telephone.. MFCCs are also increasingly finding uses in music information retrieval applications such as genre classification, audio similarity measures, etc. [8]

  3. Feature engineering - Wikipedia

    en.wikipedia.org/wiki/Feature_engineering

    getML community is an open source tool for automated feature engineering on time series and relational data. [23] [24] It is implemented in C/C++ with a Python interface. [24] It has been shown to be at least 60 times faster than tsflex, tsfresh, tsfel, featuretools or kats. [24] tsfresh is a Python library for feature extraction on time series ...

  4. Harmonic pitch class profiles - Wikipedia

    en.wikipedia.org/wiki/Harmonic_pitch_class_profiles

    After getting the HPCP feature, the pitch of the signal in a time section is known. The HPCP feature has been used to compute similarity between two songs in many research papers. A system of measuring similarity between two songs is shown in Fig.3. First, time-frequency analysis is needed to extract the HPCP feature. And then set two songs ...

  5. Mel scale - Wikipedia

    en.wikipedia.org/wiki/Mel_scale

    The first version of Google's Lyra codec uses log mel spectrograms as the feature-extraction step. The transmitted data is a vector-quantized form of the spectrogram, which is then synthesized back to speech by a neural network.

  6. Audio time stretching and pitch scaling - Wikipedia

    en.wikipedia.org/wiki/Audio_time_stretching_and...

    One way of stretching the length of a signal without affecting the pitch is to build a phase vocoder after Flanagan, Golden, and Portnoff.. Basic steps: compute the instantaneous frequency/amplitude relationship of the signal using the STFT, which is the discrete Fourier transform of a short, overlapping and smoothly windowed block of samples;

    (The Center Square) – President-elect Donald Trump, who is set to take office Monday, has made a series of promises of major executive actions on “day one” in office. One of the simplest and ...

  8. Hough transform - Wikipedia

    en.wikipedia.org/wiki/Hough_transform

    The Hough transform is a feature extraction technique used in image analysis, computer vision, pattern recognition, and digital image processing. [1] [2] The purpose of the technique is to find imperfect instances of objects within a certain class of shapes by a voting procedure.
