Pro Subharmonic


Low-end power you can feel

Bring a thunderous presence to film and TV soundtracks, beef up instrument sounds, and boost the boom in your music with Pro Subharmonic—an epic-sounding Pro Series 64-bit AAX plugin that enables you to generate low frequency signals an octave lower than the source. The synth offers a wealth of features that enable you to take precision control of the low end, including MIDI control of the effect’s frequency range.

Punch up bass and percussive sounds for creative music applications. Or bring explosive power to soundtracks in audio post by feeding signals into L/R and LFE (low-frequency effects) channels. With a wide range of controls and an easy-to-use interface, Pro Subharmonic provides a booming addition to your bottom line.

Pro Subharmonic is included in the Avid Complete Plugin Bundle, which is also included with all Pro Tools Ultimate subscriptions and 1-Year Software Updates + Support Plans.


  • Four-way range selector

    Create subharmonics from different parts of the signal’s frequency spectrum—use lower settings to add power to kick drums and explosions, and higher settings to add fatness to bass lines and low-mid instruments

  • High and low-pass filters

    Shape sounds by fine-tuning the frequency content of the synthesized effect using high- and low-pass filters, each with an adjustable cutoff frequency and Q control

  • Independent level controls

    Refine sounds to perfection using independent level controls for the Lower Synthesized Band, Upper Synthesized Band, and Direct Bass Band

  • MIDI note input

    Get fine control of the range setting using MIDI note input, which acts as a “sweet spot auto-aligner” that retunes the entire plugin’s filter chain every time you play a new note

  • Multichannel formats

    Generate and control subharmonic signals in mono, stereo (L/R), or an LFE (low-frequency effect) channel for multichannel formats, including 5.1, 6.1, 7.1, and 7.1 SDDS

  • Soft saturation feature

    Generate cleaner low-end signals—without low-frequency distortion

  • Subharmonic generation

    Take precision control by turning up or down synthesizer feeds from the Center, Front, and/or Surround output channels when using with multichannel tracks

  • Wet/Dry controls

    Control the level of synthesized signal to LFE and L/R channels
