extractors

Documentation

• HPSS Extractor
  HPSS (Harmonic-Percussive Source Separation) is a classic audio decomposition algorithm that splits a signal into three streams.
• Spectral Envelope Extractor
  Speech and many instrument sounds can be modeled as a "source" (the buzzing of vocal cords, the buzz of an oboe reed, the noise of a snare) passed through a…
• Transient Extractor
  Every K2K extractor produces two outputs: extracted (the part you asked for) and rejected (everything else).
• Noise Floor Extractor
  Every recording has a noise floor: the constant low-level content that's not the intended program material — mic self-noise, preamp hiss, room tone, HVAC…
• Micro Transient Extractor
  Where the regular Transient Extractor catches musical attacks (drum hits, plucks, plosives — events with 10–100 ms attack windows), the Micro Transient…
• Extractors
  X-ray vision for buffers.
• Pitch Class Extractor
  This node identifies and extracts every occurrence of a specific note (or chord) from the source — across all octaves.
• Temporal Envelope Extractor
  This node extracts the amplitude envelope of each frequency band — a smoothed, slow-moving version of the per-bin level over time.
• Silence Extractor
  Silence Extractor finds time regions where the input is below threshold and outputs them as a separate stream.
• Spectral Peak Extractor
  This node finds the loudest peaks in the spectrum — typically the resonances and overtones that define a sound's character.
• Formant Extractor
  Formants are the resonant frequencies of the vocal tract — the peaks in a vocal spectrum that distinguish "ah" from "ee" from "oh" without changing pitch.
