A formant filter bank and an envelope reshaper chop your signal into short, pitch-bent bark bursts, with a sub-octave for chest rumble and a glitch stutter for broken-speaker grit. Yes — it makes your guitar bark like a dog.
A.W.O.O. — Auto Wah Octave Overload
Terrarium + Daisy Seed · Mono
The bark machine on Terrarium hardware: an envelope reshaper chops your guitar into short bark bursts, a three-band formant filter gives them the nasal "woof" vowel, and each burst bends down on its tail. Sub-octave adds chest rumble and a glitch stutter breaks the bark up like a bad speaker — all on four simple two-position switches. Hold the right footswitch to howl or growl.
Signal Chain
Input → sub-octave mix (Sub) → envelope reshaper (bark bursts, Rate/Decay) → formant filter bank (~400/800/1200 Hz, shifted by Size, blended by Bark) → pitch bend (down per burst) → glitch stutter (SW4) → Volume → output.

Decay (bark length — short ruff to long wooof)
How the bark works: the reshaper opens an instant-attack gate on each trigger and lets it decay, chopping sustained notes into punchy bursts. The formant bank — three resonant bandpass filters at the dog-bark vowel resonances — colors those bursts, and a quick downward pitch bend on each one gives the bark its falling "woof" shape.

Function
SW1
Bark style — off = single woof / on = rapid yap
SW2
Trigger mode — off = pick attack / on = LFO auto-bark
Usage tip: SW2 off (pick attack) with SW1 off (single woof), Bark past noon and a short Decay turns staccato picking into clipped barks. Flip SW1 on for a yap, add Sub for a bigger dog, and flip SW4 on for a broken-speaker stutter. Hold FS2 with SW3 off to howl.

WOOF v3 + Daisy Seed · Stereo · MIDI · Expression
A bark machine. A.W.O.O. takes your guitar and makes it bark like a dog: an envelope reshaper chops sustained notes into short, punchy bursts, a three-band formant filter colors each burst with the nasal "woof" vowel, and every bark gets a quick downward pitch bend on its tail. A clean sub-octave adds chest rumble, the Size knob sets the breed from yappy small dog to deep big dog, and DIP-enabled glitch and crush degrade the whole thing into a broken-walkie-talkie snarl. Hold the second footswitch to howl, growl, or whimper.
Signal Chain
Input → sub-octave mix (Sub) → envelope reshaper (bark bursts, Rate/Decay) → formant filter bank (~400/800/1200 Hz, shifted by Size, blended by Bark) → pitch bend (down per burst) → glitch / crush (DIPs) → Volume → output. The reshaper gates first so the formant filters and bend shape discrete barks rather than a continuous tone.

Behavior
KNOB 1

Output level (0–2×).
KNOB 2
Bark
Formant filter depth — the dry/formant blend. Low = your guitar with just a hint of nasal coloring (a subtle growl); high = the signal is fully voiced through the formant bank for a full dog bark.
KNOB 3
Rate
Bark burst speed. Drives the envelope reshaper: the LFO auto-bark interval and the spacing of bursts inside a double/yap group. CCW = single deliberate woofs; CW = rapid yapping.
KNOB 4
Size
Dog size — shifts all three formant frequencies together. Left = small dog (high formants, yip); center = medium dog; right = big dog (low formants, deep woof).
KNOB 5
Sub
Sub-octave depth. Mixes a clean octave-down voice underneath the bark for chest rumble and weight.
KNOB 6
Decay
How long each bark sustains before the gate closes. Short = a tight "ruff"; long = a drawn-out "wooooof". Also sets how far the pitch bend travels within a burst.

DIP 1
Multi-bark — adds 2–3 rapid barks per trigger (excited dog). Stacks with the Rate knob and SW1 style.
DIP 2
Glitch stutter — randomly repeats tiny chunks of the bark buffer at irregular intervals, like a bark through a broken speaker. Stacks with DIP 3.
DIP 3
Sample crush — bit-reduces and sample-rate crushes the bark. Dog barking through a walkie-talkie. Stacks with DIP 2.
DIP 4
MIDI bark — Note On triggers a bark, the note sets the formant (bark pitch), velocity sets intensity. With DIP 2 + DIP 3 on, MIDI triggers glitched, crushed barks.
Triggers a bark when DIP 4 is enabled; note pitch sets the formant, velocity sets intensity.

Defaults unmapped — suggested target: KNOB 4 (Size) to foot-sweep the dog from small to large, or KNOB 3 (Rate). Assign via FS1+FS2 0.5 s Set Mode.
Usage tip: for a classic bark, set SW2 to Pick attack, SW1 to Double bark, Bark past noon, Size at center, and a medium Decay — then pick staccato and it answers "ruff ruff." Turn on DIP 1 for an excited dog, or DIP 2 + DIP 3 for a junkyard-radio snarl. Hold FS2 with SW3 on Howl for a slow "awoooo."

Hothouse + Daisy Seed · Mono · 3-position toggles
The bark machine on Hothouse hardware: envelope reshaper, three-band formant filter, sub-octave rumble, and per-burst pitch bend, with the trigger and voice options compressed into three 3-position toggles. No DIPs or MIDI. Footswitches are reversed from Terrarium per Hothouse convention — FS1 is FSW2, FS2 bypasses.
