Double-precision EQ
SW EQ uses double-precision filter coefficients and state to keep rounding error low through the filters.
AUDIO PLUGINS
Shape tone, control dynamics, and clean up tracks. A versatile suite with precise processing, familiar controls, and multi-instance editing in EQ, Comp, and Limit.
Free to use. Donations appreciated.
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
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.
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
Listen to what your processing is doing. On EQ, hear one band's contribution. On the dynamics tools, hear the difference between the original and processed signal.

CARE IN THE AUDIO PATH
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.
SW EQ uses double-precision filter coefficients and state to keep rounding error low through the filters.
SW Comp's saturation stage is fully bypassed at zero. Comp and Limit offer optional 2x and 4x HQ processing to help manage aliasing.
Internal development tests include EQ response sweeps, compressor gain-curve checks, and limiter distortion and null tests.
A NOTE FROM THE MAKER
Signalwork Audio grew out of the tools I reach for in my own sessions. I wanted the features and workflows I value across the commercial plugins I own and use, brought together in a consistent suite.
