Spectral Resonator

Ableton

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

Spectral Resonator is a resonance-based effect that transforms audio by applying tuned resonances to its spectrum, allowing you to highlight and extend chosen frequencies with adjustable decay times. It supports internal pitch modes and external MIDI sidechaining for polyphonic control (up to 16 voices), making it distinctive for both tonal sound design and pitch-driven processing aligned with musical keys.

Written from the manual and checked against it. How we check

Key Features

01Polyphonic MIDI control up to 16 voices
02Internal and MIDI pitch modes with scale awareness
03Four modulation modes: None, Chorus, Wander, and Granular
04Adjustable harmonic count with real-time spectrogram visualization
05Dual high/low-frequency damping controls (HF Damp, LF Damp)
06Harmonic spacing control via Stretch parameter (±0% to 100%)
07Unison voices with detunable partials
08Built-in limiter on Input Send with visual LED indicator

Things to Try

  • 01Set Freq to a low value, increase Unison and Uni. Amt, use Wander modulation mode with low Mod Rate and Pch. Mod values, then adjust Decay for reverb-like sounds
  • 02Convert drum or melodic audio to MIDI using Convert Harmony to New MIDI Track or Convert Melody to New MIDI Track, then route the generated MIDI track into Spectral Resonator to drive resonances from pitched material
  • 03Route a drum track through Spectral Resonator and use MIDI sidechain input to drive specific pitches, adding tonal alignment with bass or harmonic elements
  • 04Chain two Spectral Resonators in series with different MIDI inputs to each for layered, overlapping resonant structures
