Noise suppressor nodes for Web Audio API.

Demo

This package provides three noise suppression nodes.

- NoiseGateWorkletNode: A simple noise gate implementation
- RnnoiseWorkletNode: Based on xiph/rnnoise
- Using shiguredo/rnnoise-wasm
- SpeexWorkletNode: Based on xiph/speexdsp's preprocess function
- Using sapphi-red/speex-preprocess-wasm

This package requires AudioWorklet to work.

Install

``shell
npm i @sapphi-red/web-noise-suppressor # yarn add @sapphi-red/web-noise-suppressor
`

Usage

This section is written only for vite users.

`ts
import { SpeexWorkletNode } from '@sapphi-red/web-noise-suppressor'
import speexWorkletPath from '@sapphi-red/web-noise-suppressor/speexWorklet.js?url'
import speexWasmPath from '@sapphi-red/web-noise-suppressor/speex.wasm?url' // you can use vite-plugin-static-copy instead of this

const ctx = new AudioContext()

const speexWasmBinary = await loadSpeex({ url: speexWasmPath })
await ctx.audioWorklet.addModule(speexWorkletPath)

const stream = await navigator.mediaDevices.getUserMedia({
audio: true
})

const source = ctx.createMediaStreamSource(stream)
const speex = new SpeexWorkletNode(ctx, {
wasmBinary: speexWasmBinary,
maxChannels: 2
})

source.connect(speex)
speex.connect(ctx.destination)
