The example above: the highs echo on the off-beats, the lows once on beat 3.
A spectral delay by Lemmy Adam
Paint your echoes.

A spectral delay you paint on a grid. Columns are frequency bands, rows are repeats on your song’s tempo grid, and brightness is how loud each repeat is.
So the hats can echo on the off-beats while the low end repeats once on beat 3, and the mids stutter, sweep or play backwards.
Every cell is an echo.
- Across: frequency. Each column is a slice of the spectrum, lows on the left, highs on the right.
- Down: time. Each row is one step on your song’s tempo grid. The top row is now; the next is one step later, and so on.
- Brightness: level. A painted cell repeats that slice of the sound at that moment, that loud. Empty cells are silent.
Most spectral delays turn into a pretty wash. Echoplasm’s repeats are locked to the beat, so it plays like a rhythm part: it can drive a groove, not just make pads.

Each one is rendered straight from the plugin, then matched in loudness to the dry track so neither sounds better just by being louder.

Two colours, one panned hard left and one hard right, alternate down the canvas.

A shimmer colour, an octave up, climbing the spectrum with every repeat.

A reverse colour plays each repeat backwards, in quarter-note chunks.

Sprayed cells with a granular colour: glitchy, random taps.

An imported picture, played as echoes. What does a ghost sound like?
- Repeats land exactly on your song’s tempo grid, to the sample: no flams against the drums
- 8 to 128 frequency bands, from 20 Hz to 20 kHz
- Patterns from 1 beat to 4 bars, in steps from 1/4 down to 1/128, triplets included
- A dry row on top, so the canvas reads like one bar of a step sequencer
- Paint, Erase, Line, Rectangle, Fill, Gradient, Spray and Select
- Brush sizes and shapes, and dither patterns that thin out repeats or bands
- A pixel-art gradient fill: dithered blends from one colour to another, or to nothing
- Move, flip, copy and paste parts of a pattern: flip it to reverse the order of the repeats, slide it sideways to move it in pitch
- One undo step per stroke; zoom from 25 % to 1600 %
- Up to 16 colours, each its own kind of echo. Paint with a colour and those cells do what it says
- Pan, reverse, granular scatter, shimmer up to an octave either way, diffusion and ducking
- Each colour has its own level and its own share of the feedback
- Change a colour and every cell painted with it changes at once
- Up to 32 canvases (frames) in one instance
- Switch by clicking, automate the Frame parameter from your DAW, or let the sequencer step through them in time with the song
- Switches are timed to land on the beat, allowing for the plugin’s own latency
- Import a PNG, JPG or GIF and it becomes a pattern: its colours become echo colours, an animated GIF becomes frames
- Export the canvas as a GIF. It carries the whole canvas inside it, so it opens again exactly: share patterns as pictures
- Feedback repeats the whole pattern, quieter each time
- Freeze holds what’s playing and loops it for as long as you like
- Mix, Feedback, Output, Freeze, Frame and the sequencer are all automatable
Cells light up as their echoes play, as loud as they sound, over a live spectrum of your track.
About 1 % of one core for a 32 × 32 canvas in our tests, so you can use plenty of them.
Move, resize and roll up every window. Each instance remembers its own layout.
Follows your host’s tempo, even as it changes. Without a host tempo (the standalone app) it runs at 120 BPM.
Every canvas, frame and colour is saved with your project, and the same everywhere you open it.

What is a spectral delay?
A delay that splits the sound into frequency bands and echoes each band on its own. Echoplasm lets you decide, band by band and step by step, what echoes and when.
Does it work in my DAW?
If your DAW loads VST3, AU or CLAP plugins on macOS or Windows, yes. Pro Tools (AAX) support is planned after launch.
How does the trial work?
Download, install and activate the 14-day free trial from the plugin. Everything works for 14 days. When it ends, the plugin passes your audio through untouched until you buy a licence. Please use the trial to make sure Echoplasm works for you: we don’t offer refunds.
Do I need to be online?
Only once, to activate. After that it works offline. There’s also an offline activation for studio computers that are never online.
Can I move it to a new computer?
Yes. A licence covers 3 computers at once. Deactivate an old one from the plugin or your account.
