YapperWah · the talking sweep of a wah on any track, on every note, on the beat or under your hand
The talking sweep of a wah with no pedal.
Insert it on a guitar, keys, bass, synth or vocal and it quacks: on every note you play, rocked on the song's beat, or parked and swept under your hand. It sweeps the same on a quiet take or a loud one, the level stays even with the dry track, and it adds no latency.

Hear the difference
The same part, without and with Yapper.
AUTO on a funk rhythm guitar
A synthesised clean funk rhythm part on ninth chords - Auto / Funk Quack (AUTO, QUACK 5)
AUTO on a plucked keys groove
A synthesised electric-keys groove of short stabs - the slow-release AUTO preset for keys (SPEED 250 ms)
BASS on a funk bass line
A synthesised funk bass line with pops and ghost notes - Bass / Bass Envelope (AUTO, BASS on, SENSE 70 %)
SYNC sixteenths on held synth chords
Synthesised held synth chords at 120 BPM - Sync / Sixteenth Wakka (SYNC, SPEED 1/16)
A one-bar sweep on a sung hook
A dry sung hook at 128 BPM - Sync / Slow Solo Sweep (SYNC, SPEED 1 bar, QUACK 4)
PEDAL automated heel to toe under a lead line
A synthesised single-note lead line - Init with TYPE PEDAL, the PEDAL knob automated once a beat
The guitar, keys, bass and synth parts are synthesised, computed rather than played; the vocal is a sung loop. Each pair is loudness-matched.
Yapper in action
Yapper in under a minute on a synthesised funk guitar: AUTO, SENSE, PEDAL, QUACK, SPEED, SYNC, two presets and ENGAGE.
Why Yapper
No foot needed
A wah is the sound of a foot on a treadle, and in a DAW there is no foot. AUTO opens the wah on every note, SYNC rocks it on the song's grid, and PEDAL turns one big knob into the treadle, to park, automate or play from a MIDI expression pedal.
The same quack on every take
A wah driven by the track's raw level sweeps a quiet take less than a loud one. AUTO reads each note against the recent peak, so takes at -6, -14 and -22 dB in sweep the same (tested), while a softer note still opens it less.
Locked to the song
SYNC sits on the host's bar grid, not just its tempo: the heel lands on every note value of the grid, from 1/32 to a bar, triplets included, at any tempo and any start position. RETRIG restarts it on every note.
Pedal. Sense.
Two big knobs do the work: where the sweep rests, from a dark heel to a bright toe, and how far each note opens it. The sweep display and the spotlight show where the wah is now.

SYNC
Rocked on the beat.
SYNC rocks the wah heel to toe on the song's grid, from 1/32 to a bar; here on sixteenths, the rhythmic wah of funk rhythm parts.
What Yapper does
Every control has one job: the wah you hear in your head, faster.
TYPE
Three ways to wah
What moves the wah: each note (AUTO), the song's beat (SYNC), or the PEDAL knob (PEDAL). The same band and the same sound in all three, and a switch glides over 30 ms.
AUTO
Every note opens it
Each note opens the wah and it closes behind it, reading each note against the recent peak so a quiet take and a loud one sweep the same. SPEED sets how fast it closes, 30 to 400 ms: a tight quack to a slow bloom. On a held chord it stays open; use SYNC on pads.
SYNC
On the song's grid
One heel-toe-heel rock per note value, on the host's tempo and bar grid: SPEED picks 1/32 to a bar, nine values including triplets. RETRIG restarts the rock from the heel on each new note. Stopped, it keeps rocking at the host's tempo.
PEDAL
The treadle under your hand
The PEDAL knob is the treadle, 0 to 100 %: 350 Hz at the heel, dark, to 2.2 kHz at the toe, bright, with a 20 ms glide. Park it for a fixed, nasal peak, automate it, or MIDI Learn it to an expression pedal.
SENSE
How far it opens
How far each note or rock opens the wah above PEDAL, as a share of the travel, 80 % by default: 350 Hz up to about 1.5 kHz. Softer notes open it less, so your dynamics still talk.
QUACK
Smooth, vocal or quacky
The band's sharpness, Q 1 to 8, 3.5 by default: wide and smooth, vowel-like, or narrow and quacky. The level is kept even as you turn it, so QUACK never jumps the volume.
BASS
The travel for bass
Moves the travel to 250 Hz to 1.2 kHz for bass. A wah takes away the lowest notes, so lower MIX to keep some of the dry bass under it; two Bass presets start there.
Even level
More wah, not more volume
The wah's level is matched to the dry track as it plays, and every preset's average sits within 1 LU of the dry at -10, -18 and -26 LUFS in, so switching it on and off is a fair comparison.
IN, OUT, MIX and ENGAGE
Fit it to the track
IN and OUT set the gain either side, -24 to +24 dB, with meters, and a safety limiter holds the output under -1 dBFS. MIX blends the wah with the untouched track. ENGAGE crossfades in 20 ms, with no click.
15 sourced presets
Start from a wah that works
The sharp funk quack, a slower bloom for keys, gentle and full-travel versions, a slow bloom for chords, sixteenth and eighth rocks, a retriggered rock, a slow lead sweep, three parked peaks and two for bass, each built from a documented setting.
The spotlight
See the sweep
The sweep display shows where the band is between heel and toe, and a spotlight on the stage floor slides from heel, on the left, to toe, on the right, with the wah and glows with the output.
Inside the plugin
The Yapper window: two big knobs, three ways to wah, QUACK and SPEED, and a spotlight that slides with the sweep.

How Yapper compares
Three ways to wah, the same on every take, at the same level.
| Yapper | Typical wah plugins | |
|---|---|---|
| Ways to wah | AUTO, SYNC and PEDAL in one, one click apart | Often one |
| Quiet and loud takes | The same sweep at any level | Often sweeps less on a quiet take |
| Sync | Locked to the host's bar grid, 1/32 to a bar | Often free-running |
| Level | Matched to the dry; presets within 1 LU | Often jumps with the sweep |
| Bass | A travel set for bass | Often guitar range only |
| Latency | Zero, at every setting | Often added latency |
| Try-and-compare | A/B, A>B, undo and redo | Often missing |
| Hardware control | MIDI Learn on every control | Often host automation only |
| Licence | 5 computers per copy, no dongle, works offline | Often fewer activations, or a dongle |
| Updates | Lifetime updates included | Often paid upgrades |

Questions
Do I need a pedal or a MIDI controller?
No. AUTO and SYNC move the wah on their own; PEDAL can be automated in your DAW. If you have a MIDI expression pedal, MIDI Learn on PEDAL makes it a wah pedal under your foot.
Can I play through it live?
Yes. It adds no latency at any setting.
Does it work on bass?
Yes: the BASS pill moves the travel to 250 Hz to 1.2 kHz, and there are two Bass presets. A wah takes away the lowest notes, so lower MIX to keep some of the dry bass under it.
Does it follow my song's tempo?
In SYNC, yes: it reads the host's tempo and position and rocks on the grid in note values from 1/32 to a bar, triplets included. Stopped, it keeps rocking at the host's tempo (or 120 BPM).
Will it make my track louder or quieter?
No: the wah's level is matched to your dry track as it plays; every preset averages within 1 LU of the dry.
Why does the wah stay open on a held chord?
AUTO opens on each new attack and stays open while the sound holds; use SYNC on pads and sustained parts.
Can I use it on vocals or synths?
Yes. SYNC on held synth chords and a slow one-bar sweep on a sung hook are two of the preview clips.
Does it work in my DAW?
Any 64-bit DAW that loads VST3, AU or AAX plug-ins, on Windows 7 SP1 or later or macOS 10.13 or later. There is no standalone app.
How many computers can I use it on?
Up to five of your own for each copy you buy. To move it, deactivate it in the plugin on the old computer and unlock it on the new one.
Does it need the internet?
Once, to unlock it with the code we email you. After that it checks in now and then and works offline in between.
Is there a manual?
Yes. The full manual explains every control, every preset and the menus, with tips. It opens from the help key (?) in the plugin's top bar, and lives at https://lenuque.com/yapper-wah-manual.

Founder's Story
"When COVID hit, I finally had time to dive into music production—only to discover I was missing the right tools. The plugins I tried were clunky, overloaded with unnecessary features, and killed my vibe with endless tweaking. I knew there had to be a better way.
So, with my engineering background, I started making free and simple audio plugins for my producer friends. They loved them! That’s when I set out on a mission to create plugins that save you time, streamline your workflow, and keep your creativity flowing."
- Ryan Svensson (Founder & CEO)
The talking sweep of a wah. No pedal needed.
On every note, on the beat or under your hand, the same quack on any take, the level even with the dry track, and zero latency to play through.
