Harm Bright — Brightness adjustment for the harmonic component of the signal, −100 to +100. The node uses HPSS (Harmonic-Percussive Source Separation) to split the signal into harmonic, percussive, and residual streams, then lets you brighten or darken each independently. Positive values lift highs in the harmonic content (vocal sustains, sustained chord tones); negative values darken them. Useful for making vocal tone brighter without making cymbals harsher.
Perc Bright — Brightness adjustment for the percussive component, −100 to +100. Affects only the transient/percussive part of the signal (drum hits, plosive vocal sounds). Positive values make percussive elements brighter and more present; negative values dull them. Use to add cymbal sheen without affecting the rest of the mix, or to dull harsh transients without touching the sustained material.
Res Bright — Brightness adjustment for the residual component, −100 to +100. The residual is what’s left after extracting harmonic and percussive — typically room tone, breath, noise, ambient content. Positive values brighten the ambient/noise content (more air, more “space”); negative values dull it (cleaner, drier sound). Useful for shaping the spatial feel of a recording without touching the foreground content.
Mix — Equal-power blend between dry (0%) and the brightness-adjusted signal (100%). 100 is the standard fully-processed output; lower values blend the original back in for subtler shaping.
Output Gain — Output level in dB, −24 to +24. Brightness adjustments can shift overall level — use this to compensate.
About Dynamic Brightness
This node uses Harmonic-Percussive Source Separation (HPSS) to split the input into three streams — harmonic (sustained pitched content), percussive (transients), and residual (ambient/noise) — then applies independent brightness adjustments to each before recombining. The result: surgical brightness shaping that no global EQ can match. Lift just the vocal sustains without harshening cymbals, dull just the percussive transients without losing chord brightness, brighten just the room tone for an “open” feel without affecting foreground elements. Pair with the HPSS extractors if you want to route each stream to entirely different processing paths instead of just adjusting brightness.
