Additive resynthesis, trajectory smoothing

npm install @audio/sinusoidal-synth

import synth from '@audio/sinusoidal-synth'

Additive resynthesis from the partial trajectories produced by sinusoidal-track: per-sample linear interpolation of frequency/amplitude between frame centers, with phase integrated for continuity (McAulay-Quatieri 1986) — no clicks at partial start/end (one-hop fade in/out).

let model = track(data)
let out = synth(model, { length: data.length })   // → Float32Array

| Param | Default | | |---|---|---| | model | — | {partials, frames, hop, frameSize, fs} from sinusoidal-track (positional) | | length | frames·hop + frameSize | Output length, samples |

Use when: resynthesizing tracked partials — after trajectory editing/smoothing (pitch correction, formant shifting) or as the sinusoidal half of an SMS reconstruction (pairs with sinusoidal-residual for the noise layer).

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