- 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.
