Intuitive filter-design software
Create custom FIR filters & complete mixed FIR+IIR presets for single & multi-way loudspeakers (or any DSP-based audio playback device).
Filter design involves complex computations. We do the math so you don’t have to. Just follow the workflow & use the controls to set the required parameters.
Load your audio measurements to get started.
(Use Direct Design mode to build FIR filters without measurements.)
Filters & presets for EQ & so much more
Limitless customization options
Single or multi-channel FIR or FIR+IIR design.
Real-time filter calculation & FIR error display.
Multiple FIR sample rates plus independent sample rates on input filtering & each output channel.
Manual & auto FIR filter magnitude & phase adjustment, plus post-auto FIR EQ voicing.
Comprehensive range of IIR filter types across multiple processor brands.
Integrated measurement averaging.
Brand emulations & integrations
Comprehensive range of different measurement file formats supported.
SMAART® Control for live measurement streaming and capture.
Direct-to-processor (DTP) functionality. Replaces manual export/load for some amps & processors.
Automated, non-destructive resampling of imported measurements. (Measure at one sample rate and export filters at a different sample rate.)
Multiple FIR export formats for loading filters/presets into any product with user-accessible settings.
Visualize & Audition Your Designs In Real-Time
Color-customizable plots with on-plot filter mouse control.
Continuous Wavelet Transform display for time/frequency impulse response analysis.
Polar plots for understanding on and off-axis behaviour of the custom preset with polar measurements.
Built-in auditionDSP audio player + processor. LISTEN to your projects and systems.
Our filter design tools are used by a range of audio professionals, including AV designers/integrators/technicians, system engineers, acoustic consultants, loudspeaker designers, embedded audio engineers, consumer device manufacturers, audio educators & more.
