Auto-Wah
EffectsautowahModerate CPU
Envelope-following wah filter sweep. Wah CV.
What it does
Funk-style envelope-driven wah.
Wraps daisysp::Autowah. The filter sweep tracks the input envelope; Wah amount is audio-rate, while Dry/Wet and Level are init-time defaults.
Parameters
-
Wah
wahHow far the filter sweeps in response to the input envelope — the depth of the effect. At 0 the filter barely moves and the tile is close to a bypass; higher values swing it further, giving the vocal quack that the effect is named for. Because the sweep is driven by the input level rather than an LFO, how this sounds depends heavily on how dynamic your source is. Per-sample, so it can be modulated.
-
Dry/Wet
dryWetBalance between the untouched signal and the filtered one, on a 0 to 100 scale rather than 0 to 1. Keeping some dry signal preserves the attack and body of the source while the wet part supplies the movement, which is usually what you want on anything percussive. ⚠ Baked at build time, so this is set when the firmware is built and cannot be changed while the patch runs.
-
Level
levelOutput gain for the tile. The filtering can take a noticeable amount of level out of the signal, so this exists to put it back and match the effect against the rest of the patch. ⚠ Baked at build time, so it is a fixed trim rather than something to automate.
Envelope-follower-driven filter sweep. Dry/Wet (0–100) and Level are baked at init; Wah is per-sample so the port can be modulated.
