echo

An ambisonic delay with four taps that rotate around the listener as they repeat

taps

four delay taps

Presets for all four taps at once — even, ping-pong, spiral, cascade, single; double-click one to reset its values. Below, the four taps on a timeline: click a row to edit that tap.

taps · timing

delay time

In milliseconds, or synced to the tempo in sixteenth notes.

  • time · steps · the delay time
  • offset · offset steps · when the tap starts
  • swing · shifts a synced tap off the grid

taps · axis

rotation axis

Each tap rotates around its own axis, set by azimuth and elevation. Pointing straight up, the tap circles the listener.

taps · every pass

what changes with each repeat

Applied again on every repeat, so the echoes move, fade and blur.

  • spin · rotation per repeat; 180° is a ping-pong
  • skew · how far each repeat slides along the axis
  • feedback · blur · how quickly the repeats fade, and how diffuse they get
  • band · low-cut and high-cut filters in the feedback path

send

which directions go into the delay

The send region picks the directions that feed the delay: all of them by default, or a spot, a band, sectors, dots or clouds.

the scene

where each echo comes from

Point the probe at a direction, and the 3D view shows where each echo of a sound from there arrives, as dots along a spiral around the tap's axis, over the incoming signal's energy.

The slide along an axis is the warp of Pomberger and Zotter, on the foundations page.
