SW EQ
Shape tone with dynamic EQ and per-band audition.

Silent recording of SW EQ. A changing frequency spectrum moves beneath a fixed EQ curve with a low-frequency cut and several bands.

MULTI-INSTANCE EDITING

Edit several tracks from one window

Open Instances in SW EQ, Comp, or Limit to select and edit another instance of that same plugin. Keep working across tracks without hunting through the mixer.

Available inEQCompLimit

Silent recording of SW EQ switching from Vocal to Bass and then Piano in the Instances list. EQ bands are adjusted in the same editor as the selected instance changes.

A CLOSER LISTEN

Hear the difference

Listen to what your processing is doing. On EQ, hear one band's contribution. On Comp, De-Ess, and Limit, hear the difference between the original and processed signal.

Right-click and hold to audition.

One band. Just its contribution.

CARE IN THE AUDIO PATH

How the audio is processed

Good utility plugins need more than a useful feature list. At Signalwork Audio, development includes checks on what happens to the audio as it passes through the processor.

PRECISION

Double-precision EQ

SW EQ uses double-precision filter coefficients and state to keep rounding error low through the filters.

CONTROL

Quality without a setting

SW Color uses automatic internal upsampling to reduce unwanted digital artifacts, with no oversampling setting to manage. Playback and export use the same processing.

VALIDATION

Checks on the audio itself

Internal development tests include frequency response, gain curves, distortion, aliasing, and comparisons that check whether an optimization changes the sound.

A NOTE FROM THE DEVELOPER

Premium features, all in one place.

Even with plenty of paid plugins, I kept switching between tools that did the same job. Each had something I liked, but there was always a feature or two I missed. So I built my own plugins to bring those features together.

Signalwork Audio plugins are made to be quick, easy to use, and sound great. I'm sharing them with the community for free. Feedback and feature requests are always welcome.

PARAMETRIC + DYNAMIC EQ

SW EQ

Shape the tone.
Hear every move.

Make broad tonal changes or work on a single resonance. Then listen to exactly what each band contributes, with true per-band delta audition.

  • Up to 24 bandsBell, shelves, filters, notch, band-pass, and tilt.
  • Dynamic EQ per bandLet a band respond when the signal needs it.
  • Multi-instance editingSelect and adjust other EQ instances from this window.
  • Auto-gainCompare tone with less loudness bias.

SW Comp

Silent recording of SW Comp. Input and output histories scroll across the display while the gain-reduction trace and meters respond during playback.

TRACK COMPRESSION

SW Comp

Compression with a little character

Set the movement and feel of a track with clear level history and gain-reduction feedback. Add saturation when you want some character.

  • Multi-instance editingMove between your Comp instances in the same editor.
  • Clean, Punch, SmoothThree starting points. Your controls stay live.
  • Optional colorBlend in saturation, or leave it fully off.
  • See the dynamicsFollow input, output, and gain reduction together.

SW Color

Silent capture of the actual SW Color editor processing a generated signal. The measured glow radiates around Drive as Preamp, Tube, and Tape are selected. No music is included.

PREAMP, TUBE + TAPE SATURATION

SW Color

A little warmth.
A different attitude.

Bring density, harmonic color, and movement to a track. Choose Preamp, Tube, or Tape, push the central Drive control, then shape how the sound holds together.

  • Three distinct stylesPreamp for density and edge, Tube for warmth and bloom, Tape for rounded weight.
  • Soften or preserveBring up body and soften peaks, or emphasize attacks. Dynamics has its own On/Off switch.
  • Automatic internal upsamplingLess unwanted digital artifacting, with no quality switch to second-guess.
  • Optional Auto GainMatch levels as you compare. Leave it off to keep the natural Drive-related rise.

SW De-Ess

Silent recording of SW De-Ess with Full Band detection and Split processing selected. The waveform and level meters respond during playback.

VOCAL SIBILANCE CONTROL

SW De-Ess

Tame the esses.
Keep the brightness.

Voice mode is designed to tell a sharp “s” or “sh” from a bright vowel, so you can deal with sibilance without reacting to every bright sound.

  • Voice detectionLooks at more than high-frequency level.
  • Split or WideReduce the sibilant band or the whole signal.
  • Audition as you adjustHear what the detector is catching.

SW Gate

Silent recording of SW Gate. A transfer curve shows the expansion settings while the level history and input and output meters respond during playback.

GATING + EXPANSION

SW Gate

Less spill.
More of the take.

Reduce quiet noise and spill between the phrases or hits you want to keep. Choose a firm gate or gentler expansion, then set how it opens and closes.

  • Gate or expandSet the amount of separation the track needs.
  • Choose the triggerUse this track or an external sidechain to trigger the gate.
  • Shape the timingDial in attack, hold, release, and lookahead.

SW Limit

Silent recording of SW Limit in Transparent mode. Input, output, and gain-reduction meters move as the signal reaches the limiter.

PER-TRACK PEAK CONTROL

SW Limit

A ceiling for stray peaks

Take care of stray peaks before a track reaches your bus processing. A straightforward peak catcher for individual tracks.

  • A firm sample ceilingSet the output ceiling and control the peaks.
  • Multi-instance editingSelect and adjust other Limit instances in one editor.
  • Adaptive releaseRecovery adjusts to the signal.
  • Linked controlsMove threshold and output together when useful.

Release notes

  • The Microsoft Visual C++ runtime is now built into each plugin. On 1.0.8 and earlier a PC without it loaded none of the plugins, and most DAWs gave no reason why they were missing.
  • If you already installed that Microsoft runtime, you can leave it alone. Other software may be using it.
  • No change to sound, controls or saved settings. The plugins are otherwise identical to 1.0.8.
  • macOS is unchanged at 1.0.8.
