@audio/aiff-encode

Encode PCM audio samples to AIFF format. Pure JS — no WASM, no native bindings, works in both node and browser.

import aiff from '@audio/aiff-encode';

const encoder = await aiff({ sampleRate: 44100 });
encoder.encode(channelData);    // buffer PCM
const buffer = encoder.flush(); // → complete AIFF file as Uint8Array

Options

| Option | Default | Description | |--------|---------|-------------| | sampleRate | — | Sample rate (required) | | bitDepth | 16 | 16 or 24 |

Streaming

const encoder = await aiff({ sampleRate: 48000, bitDepth: 24 });
encoder.encode(chunk1);
encoder.encode(chunk2);
const file = encoder.flush(); // → Uint8Array (complete AIFF)
encoder.free();

Input is Float32Array[] — one array per channel. Big-endian interleaving handled automatically.
