Clean the low end
Use the high-pass filter on vocals, guitars, synths and percussion to remove unwanted rumble and low-frequency buildup. This helps keep the low end cleaner and gives kick and bass more room in the mix.
AFILTER FREE
A versatile high-pass and low-pass filter for cleaning up tracks, shaping tonal balance, and creating steep frequency cuts.
VST3 CLAP Standalone Windows 64-bit

IN THE MIX
Clean Up Tracks and Shape Their Frequency Range
Use AFILTER when a track needs a cleaner frequency boundary, not a complex series of corrective EQ moves.
Tame Excessive High Frequencies
Use the low-pass filter to tame harsh synths, noisy samples, bright percussion and effects. Control unwanted high-frequency content and reduce harshness without making unnecessary changes to the rest of the spectrum.
Shape the transition
Adjust resonance to emphasize frequencies around the cutoff point. Automate cutoff and resonance settings to create filter sweeps, transitions and evolving effects, or use subtle filtering to shape individual tracks and groups.
FILTER & MONITORING
Essential Controls for Precise Filtering
Independent HPF and LPF
Set the low- and high-frequency boundaries separately to clean up a track or shape its overall range.
Choose the cutoff frequency
Set the cutoff frequency independently for the high-pass and low-pass filters.
Set the filter slope
Choose 12, 24, 36, 48 or 96 dB/oct, or select Brickwall for an especially steep cutoff.
Shape the resonance
Control the resonance around the cutoff frequency and adjust the filter curve to achieve the desired response.
Monitor Your Processing
Use Delta monitoring to hear the difference between the original and filtered signals. Level Match helps you make more accurate A/B comparisons without loudness influencing your judgment. Resonant peaks above 0 dB are gently rounded by the SmoothTanh saturation stage.
DESIGNED FOR FOCUSED FILTERING
Built for Everyday Mixing and Sound Design
AFILTER brings the essential tools for shaping frequency boundaries into one straightforward workflow.
Straightforward Filtering
Independent high-pass and low-pass filters make it easy to remove unwanted frequencies and shape the tonal balance of individual tracks.
Creative Sound Shaping
Adjustable resonance and filter curves let you move beyond basic cleanup and create more pronounced filtering effects.
Practical Monitoring
Delta monitoring and Level Match help you evaluate filter changes and make more informed processing decisions.
WORKFLOW & CONTROL
DAW Automation and Project Recall
Automate AFILTER parameters directly in your DAW. Change cutoff frequencies, resonance and other available controls over time to create filter sweeps, transitions and evolving sound effects.
AFILTER settings are saved with your DAW project, so your filter configuration is restored when you reopen the session.
