Set Different Decay per Frequency | Prism Reverb Ableton

Max For Live Audio Device

Standard reverb applies the same decay time to every frequency in your mix. Bass and treble sustain equally, which means either the low end accumulates and muddies the tail, or you shorten the decay and lose the shimmer you needed in the highs.

Prism Reverb gives you a crossover point you can set anywhere between 400Hz and 5500Hz, then independent multipliers for how the frequency content below and above it decays. The bass clears at the rate you specify. The highs sustain at the rate you specify. The two don’t have to be the same.

What Prism Reverb Does

Prism Reverb runs on Max 9’s abl.dsp.prism~ object, the same algorithm that powers the prism mode inside Ableton’s Hybrid Reverb, with the crossover and multiplier controls fully exposed on a single interface.

The crossover sets the frequency dividing point: everything below it follows one decay behaviour, everything above it follows another. The Lowmult and Highmult controls then set how much shorter or longer each frequency range decays relative to the main decay time.

Set Lowmult below 1.0 for a tight bass tail that clears quickly; set Highmult above 1.0 for treble that sustains and shimmers long after the bass has gone. Decay runs from 0.1 seconds to 60 seconds, room size controls virtual space dimensions, and freeze mode sustains the tail indefinitely.

The Pro edition adds a real-time spectrum display, interactive three-band EQ with draggable control points, integrated stereo width, and visual damping response, all post-reverb, all in one device.

Prism Reverb — Use Cases

House music kick and bass on a send channel, set the crossover below the bass fundamental, dial Lowmult down so the low frequencies clear quickly while Highmult lets the upper room sustain naturally
Vocal reverb in deep house or UK garage where you need air and space in the top but no low-mid chest resonance cloud building in the tail
Snare and clap reverb in tech house where the high-frequency tail shimmers but the 100–200Hz body of the snare clears fast so it doesn’t fill the groove between hits
Creating textures where high-frequency content sustains much longer than the bass, combine freeze with high Highmult and low Lowmult for evolving spaces that feel much larger than the source
Subtle send reverb across a mix bus where a low Lowmult keeps the master clear while the highs still get room

Prism Reverb | Frequently Asked Questions

How do I stop reverb making my bass frequencies muddy in Ableton?

The standard approach is either shortening the overall decay (which also reduces the high-frequency shimmer you wanted) or putting a high-pass filter after the reverb (which removes the bass tail rather than shaping it).

Prism Reverb’s crossover and Lowmult control give you a third option: set a crossover point below your bass content, then dial Lowmult below 1.0 so the bass frequencies decay faster than the main tail. The bass clears. The mids and highs sustain at whatever rate you set with Highmult.

You’re shaping the tail rather than cutting from it.

How is this different from using Ableton’s Hybrid Reverb prism mode?

It uses the same abl.dsp.prism~ DSP engine, the core algorithm is identical. The difference is control access and workflow. Hybrid Reverb’s prism mode sits inside a complex multi-panel interface where adjusting the crossover, multipliers, decay, and mix simultaneously requires switching between views.

Prism Reverb puts all of those controls on a single surface, tuned specifically for the crossover workflow, Lowmult and Highmult are the primary controls, the crossover range is explicit, and every parameter is immediately automatable without panel switching.

Which version of Ableton Live and Max for Live does Prism Reverb require?

Prism Reverb requires Ableton Live 12.0.5 or higher with Max for Live 9.0.9. Live Suite includes Max for Live. If you’re on Live Standard, the Max for Live add-on is available separately from Ableton.

The device runs on macOS 10.13 or later and Windows 10 or later, installs directly into your Live browser, and saves inside your project file with no external activation. The Standard edition is available free on maxforlive.com.

How is this different from Dark Hall Reverb or Quartz Reverb?

All three ProducerStack reverbs solve different frequency-related mixing problems. Dark Hall is built for large spaces where bass accumulates, its crossover and multiplier control the low end relative to a dense hall tail.

Quartz is built around dual damping, independent high and low frequency damping controls through a diffusion algorithm, shaping how frequencies roll off over time.

Prism is built around frequency-dependent decay via a crossover, you set an explicit Hz dividing point and independent multipliers for each side.

The architecture is different; which one you reach for depends on the character you’re trying to shape.
