This bit walks through the Delay section of Ableton's Spectral Time device, covering both the standard controls and the frequency-based parameters that make it distinctive. Dry/Wet, Feedback, and delay time (set in milliseconds or note divisions) work as expected, but the real character of the device comes from what happens next.
Shift transposes the pitch of the delay output up or down, so each repeat drifts away from the original. Tilt delays high or low frequencies by different amounts depending on the direction you push it, producing a pitch-bend-like smear across the repeats. Spray randomizes the delay time itself, making the effect feel looser and more abstract.
Mask ties these together by restricting where Tilt and Spray act in the frequency spectrum. Positive values confine them to higher frequencies, negative values to lower ones, giving you precise control over which part of the sound gets treated. A Stereo width control rounds out the section.
