Delay Feedback Tail

Estimate repeats and time until a feedback loop falls below a level.

Your result
Repeats to cutoff
9.965784
Tail (ms)
99.65784

How this works

repeats = cutoff dB / (20 × log10(feedback)); time = repeats × delay

Use the result carefully

Assumes a linear, unfiltered loop and no saturation. Use a negative cutoff; positive values produce zero repeats.
