Karplus-Strong plucked string

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.
