Karplus-Strong plucked string

npm install @audio/synth-pluck

import pluck from '@audio/synth-pluck'

Karplus-Strong plucked string (Karplus & Strong 1983): a seeded noise burst circulates through an averaging delay loop sized to the pitch period, decaying via the loop's damping factor. Pitched — (freq, opts).

pluck(220, { damp: 0.996, duration: 1.5 })   // → Float32Array

| Param | Default | | |---|---|---| | freq | — | Hz (positional) — sets the delay-loop length | | duration | 1 | Seconds | | amp | 0.7 | Noise-burst amplitude | | damp | 0.996 | Loop damping — closer to 1 decays slower | | seed | 1 | PRNG seed for the excitation burst | | fs | 44100 | Sample rate |

Use when: plucked-string/guitar-like tones without a physical model; cheap and classic.

Part of @audio/synth — the synth family umbrella.
