Description
Signalwork Audio Suite is a free collection of eight standalone mixing plugins: SW EQ, SW Comp, SW Color, SW De-Ess, SW Gate, SW Limit, SW Image, and SW Attack. Suite 1.3.0, released October 13, 2026, adds the four-band SW Attack transient shaper after SW Image joined in version 1.2.0.
The suite keeps its listening-focused workflow. SW EQ offers per-band delta audition, Comp, De-Ess, and Limit let you hear the processing difference, and EQ, Comp, Limit, Image, and Attack can switch between other open instances of the same plugin from one editor.
SW EQ provides up to 24 bands with dynamic processing, while SW Comp combines three response styles with optional saturation and oversampling. SW Color covers Preamp, Tube, and Tape saturation, and the De-Ess, Gate, and Limit plugins handle sibilance, spill, expansion, and per-track peak control.
SW Image adjusts stereo width from mono to 200%, can narrow low-frequency Side content, and includes a stereo-field display with correlation metering. SW Attack splits the signal into four bands with three movable crossover points, Attack and Sustain controls, band linking and solo, ten presets, and a soft output ceiling with zero added latency.
The suite remains free and complete through its official Gumroad page. The universal macOS installer supplies AU and VST3 formats for macOS 11 or later, while the Windows 10/11 x64 package supplies eight VST3 folders for manual installation.
Frequently Asked Questions
Which plugins are included in Signalwork Audio Suite?
Suite 1.3.0 includes eight standalone plugins: SW EQ, SW Comp, SW Color, SW De-Ess, SW Gate, SW Limit, SW Image, and SW Attack. They cover tone shaping, compression, saturation, sibilance control, gate or expansion, per-track limiting, stereo imaging, and four-band transient shaping.
What is delta audition in SW EQ?
SW EQ can audition the delta for an individual band, meaning you can listen to the material that band is changing. This can make it easier to decide whether a boost, cut, or dynamic action is helping the source.
Can I edit several tracks from one Signalwork plugin window?
Yes. The developer documents multi-instance editing in SW EQ, SW Comp, SW Limit, SW Image, and SW Attack, allowing another open instance of the same plugin to be selected from the current editor when the DAW runs them in the same host process.
Is SW Limit intended for mastering?
No. Signalwork describes SW Limit as a per-track limiter for catching peaks before bus processing. It uses lookahead and does not claim zero latency, so it should not be represented as a dedicated mastering limiter.
What changed in Signalwork Audio Suite 1.3.0?
Version 1.3.0 adds SW Attack, a four-band transient shaper with movable split points, per-band Attack and Sustain controls, linking, solo, ten presets, multi-instance editing, and an always-on soft ceiling. Signalwork says the other seven plugins are unchanged from Suite 1.2.0 and existing projects continue to open as before.
