Calculate a nominal tempo-linked delay interval and an explicit below-100% feedback/decay-threshold model without predicting plugin or signal behavior.
A quick decision brief for this specific tool
Documented BPM and reference note, one straight/dotted/triplet delay value, entered feedback below 100%, and an explicit amplitude decay threshold
Nominal delay interval plus transparent ideal feedback passes above the threshold and the first pass at or below it
Scale note units from the BPM reference pulse, then solve feedbackⁿ against the entered threshold without labeling the geometric passes audible repeats
Choose your path
Calculate one nominal tempo-linked delay interval and a transparent below-100% feedback/amplitude-threshold boundary without predicting audible repeats, reverb or device behavior.
Enter one dotted or triplet delay on a device without reliable note sync.
Copy tempo/reference pulse, choose the delay note and test the returned milliseconds in the actual pedal.
Keeps routing, tone, level, latency and musical acceptance outside the arithmetic.
Make the repeat-decay convention auditable.
Enter the plugin feedback and an explicit amplitude threshold, then compare the geometric pass boundary with the rendered waveform.
Does not call ideal amplitude passes audible repeats.
Avoid one fixed millisecond value across a changing map.
Run each documented tempo segment separately and verify automation/host compensation in the session.
Uses the calculator as a starting record rather than a set-and-forget control.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.

Plan nominal source and target audio frame counts, rate ratio, Nyquist limits, and integer-frame duration reconciliation without uploading or converting audio.
Calculate delay time in milliseconds from BPM for rhythmic delay effects. Quarter, eighth, dotted, and triplet note delay values.
Convert delay time in milliseconds to equivalent acoustic distance. Free delay time distance tool for delay, time, and more.
The documented BPM and its stated reference note define one pulse duration. This avoids assuming every clock or score uses quarter-note BPM.
Reference beat ms = 60,000 / BPMStraight, dotted, and triplet selections use explicit quarter-note units relative to the selected BPM reference note.
Delay ms = reference beat ms × selected quarter units / reference-note quarter unitsFor feedback below 100%, the ideal returned amplitude after n passes is feedbackⁿ. The calculator reports the first pass at or below the entered amplitude threshold, not an audible-repeat promise.
First boundary pass = ceil(log(threshold ratio) / log(feedback ratio))Updated: August 2026
Calculate the nominal dotted-eighth interval, then test the pedal's clock, feedback, filtering and bypass/latency behavior at safe listening level.
Record the plugin feedback percentage and a chosen amplitude threshold, then compare the geometric pass count with the rendered waveform rather than calling it audible repeats.
Recalculate intervals for each tempo segment and verify automation/device sync because one fixed millisecond value cannot follow a changing map.
Record the actual note selection and reference beat together; a dotted eighth is 0.75 quarter-note units, while an eighth is 0.5.
Treat it as a transparent amplitude-threshold model, then inspect the real rendered waveform and listen at an appropriate level.
Enter the documented tempo, BPM reference note, and one straight, dotted, or triplet delay value. Feedback is modeled only as an ideal amplitude ratio against your stated threshold; the page does not calculate reverb, process audio, or know the device's feedback topology.
