Gist is a C++ audio analysis library intended for use in real-time applications. It contains a range of audio analysis algorithms, including:

  • Simple Time Domain Features (e.g. RMS, Zero Crossing Rate)
  • Simple Frequency Domain Features (e.g. Spectral Centroid, Spectral Flatness)
  • Onset Detection Functions (e.g. Energy Difference, Complex Spectral Difference)
  • Pitch Detection
  • Mel-frequency Representations (e.g. Mel-frequency Spectrum, MFCCs)

Gist is a core part of the Sound Analyser audio plug-in.
