Set the difficulty to Easy and leave only Delay Time active. Press New Round, toggle between Target and Yours, then turn the Delay Time knob until the repeats line up rhythmically. Watch the Echo Timeline — each repeat is a bar that decays left to right. Press Check Match when you're ready.
Click the parameter pills to add Feedback and Wet/Dry to the challenge once Delay Time feels solid.
Delay Time — the gap between the original sound and its first echo. Short times (under 100ms) produce slapback or doubling; longer times (300ms+) give distinct, separated repeats. Tap along to the rhythm of the echoes to estimate the interval, and use the BPM readout above the timeline as a sanity check.
Feedback — how much of the delayed signal is fed back into the delay line, setting the number of repeats. Low feedback (20–30%) fades after one or two echoes; high feedback (80%+) builds many sustaining repeats. On the timeline this is the slope of the decay — steep means low feedback, shallow means high.
Wet/Dry — the balance between the delayed signal and the dry original. High wet pushes the echoes forward and prominent; low wet keeps the dry sound up front with echoes trailing subtly behind. On the timeline it scales the overall height of the echo bars relative to the dry hit.
Use Space to A/B between Target and Yours, and D to drop to the dry signal and re-anchor your sense of the original.
