## What is Seyfert?

Seyfert is a delay unlike your others: every echo spawns at its own place in an orbit around you, and the whole constellation slowly revolves.

Turn up Feedback and you don't just add repeats, you spawn more echoes into the orbit, from a single tight slap to a dense, spiralling cloud. Spin revolves the whole field around you. Doppler bends the echoes in pitch as they whirl toward and away. 3D wraps them around your head on headphones.
Lift the repeats an octave into crystalline shimmer, drop them a sub-octave for weight, or detune them into a chorus. A lush reverb blooms around the echoes, never the dry signal, so your source stays clear while the repeats dissolve into space.

Features:

- Orbital echoes, where Feedback sets how many circle you
- Spin, from a gentle drift to a full whirl
- Doppler pitch-bend as the orbit turns
- 3D binaural imaging for headphones
- Shimmer and transpose, up or down one octave (octaves, fifths, sub-octaves)
- Per-echo Trail tone, tape Wobble, and Drive
- Lush reverb applied to the echoes
- Full 5-band EQ on the wet signal
- Orbit and Ping-Pong patterns, tempo sync
- 18 factory presets, plus save your own
- Standalone app and Audio Unit (AUv3) for GarageBand, AUM, Logic, and more

No accounts, no tracking, no data collected. Everything stays on your device.

### 5/5 — Just what I was looking for

*2026-08-21*

The app implements Binaural features into a creative delay effect. Such a great idea. 

The developer, Konstantin Torsten, is responsive and was willing to help with my particular request of lowering the iOS requirement to the iOS 15. Thank you for lowering the iOS requirement. Thus I was able to buy the app. It works great, no issues thus far.
