@audio/spatial-delay

Per-channel delay in ms/samples (FFmpeg adelay)

npm install @audio/spatial-delay

import delay from '@audio/spatial-delay'

Per-channel integer-sample delay, zero-filled at the head (or tail, for negative shifts) — the FFmpeg adelay filter. Modifies each channel in place via copyWithin.

delay(channels, { delays: [0, 15] })   // right channel delayed 15ms, both modified in place

| Param | Default | | |---|---|---| | delays | [] | Per-channel delay, milliseconds | | samples | — | Per-channel delay, samples — overrides delays when given | | fs | 44100 | Sample rate |

Use when: aligning channels for Haas/decorrelation effects, or as the delay primitive under spatial-surround's Ls/Rs decorrelation.

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