Auto Filter

Ableton

Where to get itIncluded with Ableton Live. It is part of that DAW, not a separate download.ableton.com

Auto Filter is a dynamic filtering effect that applies frequency-selective filters to incoming audio, offering ten filter types (Low-pass, High-pass, Band-pass, Notch, Morph, DJ, Comb, Resampling, Notch + LP, and Vowel) with emulated analog circuit models. It combines LFO modulation with envelope follower capability—responding to either the filtered signal or external sidechain input—to create dynamic, tone-sculpting effects. The device's independent stereo LFO modes and multiple filter circuit types (SVF, DFM, MS2, PRD) make it distinctive for creating everything from subtle sweeps to aggressive resonant effects.

Key Features

0110 filter types (Low-pass, High-pass, Band-pass, Notch, Morph, DJ, Comb, Resampling, Notch + LP, Vowel)
024 filter circuit models (SVF, DFM, MS2, PRD) emulating classic analog designs
03Independent stereo LFO with Phase and Spin offset modes
048 LFO waveforms including Sine, Triangle, Saw, Square, Ramp Up, Ramp Down, Wander, and S&H
05Envelope follower with Attack, Hold, and Release controls
06External sidechain input with frequency-selective filter and mixing controls
07Drive control for saturation and distortion effects
08Soft clipping output protection with visual clipping indicator

Things to Try

  • 01Use the Morph filter with stepped LFO quantization (Steps mode) to create rhythmic band-pass transitions that track the tempo
  • 02Apply Drive values above 0.0% with the DFM circuit type to achieve warm, saturated tones while sweeping the filter cutoff
  • 03Enable the External sidechain with a high-pass Sidechain Filter type to make the envelope follower respond only to bright frequencies in an external track
  • 04Set the Envelope Hold toggle on to ensure the attack phase completes fully before entering release, creating more pronounced dynamic response
