Seyfert

Orbital delay‑reverb for iPhone, iPad & Mac

Seyfert (named after a Seyfert galaxy — a galaxy with a brilliant, active nucleus) is a delay where every echo spawns at its own place in orbit around you, and the whole constellation slowly revolves. Turn up the feedback to spawn more orbiting echoes, spin the field, bend them with Doppler as they whirl past, lift them an octave into shimmer, and wrap the repeats in a lush reverb. Use it on its own or as an Audio Unit (AUv3) effect inside your favourite music app.

Quick start

Standalone: hit Play to run the built‑in demo through the effect, or switch the source to your microphone or import a song.
As a plugin: load Seyfert as an AUv3 audio effect in GarageBand, AUM, Logic, or any AUv3 host, and drop it on any track.
Dial it in: set the delay Time (or Sync to your project tempo), then Feedback sets how many echoes populate the orbit — from a single slap to a dense spiralling cloud. Shape the sound with the grouped panels: Delay, Orbit, Character, Reverb, EQ, Output.
Spin it: raise Spin to revolve the whole field, add Doppler for a pitch‑bend as echoes whirl toward and away from you, or 3D for a binaural orbit around your head on headphones.
Presets: browse the factory presets with the arrows in the header (Quarter Orbit, Dotted Edge, 3D Carousel, Aurora, Choir of Moons, Gravity Well, Black Hole, Warp Drive…) and save your own.

FAQ

What makes Seyfert different from a normal delay? Each echo is placed at its own position in an orbit around you, and Feedback controls how many echoes populate that orbit — from one tight slap to a dense, spiralling cloud. The whole constellation can slowly revolve (Spin), and the reverb is applied to the echoes only, never the dry signal — so the repeats bloom into space while your source stays clear.

What is Doppler? As the orbit spins, echoes moving toward and away from you bend in pitch, like a passing siren. It only takes effect while Spin is up, so the two live side by side in the Orbit panel.

What can it do beyond a plain delay? Orbital and Ping‑Pong placement patterns, 3D binaural imaging, a squared Spin control from a gentle drift to a full whirl, Doppler pitch‑bend, per‑echo Trail tone, tape Wobble (wow & flutter), tape Drive, a shimmer/transpose Pitch (±1 octave — rising octaves, fifths, or sub‑octave echoes), a lush FDN reverb on the echoes, and a full 5‑band EQ on the wet signal.

Does the 3D work on speakers? The 3D (binaural) mode places echoes around your head and is designed for headphones. On speakers you still get a wide stereo orbit; the front/back depth is a headphone effect.

Does it work with my other music apps? Yes. Seyfert runs as an Audio Unit (AUv3) audio effect inside hosts like GarageBand, AUM, and Logic, with full host preset and parameter automation support.

Why does it ask for the microphone? Only in the standalone app, and only if you choose the microphone as the input source, so the effect can process live audio. Nothing is ever recorded, uploaded, or shared. As an AUv3 plugin, the host provides the audio and no microphone access is needed.

Does it collect any data? No. Seyfert collects nothing and has no tracking. See the Privacy Policy.
