@caitun/speex

Browser Speex encoder and decoder powered by Speex compiled to WebAssembly.

Install

npm install @caitun/speex

Usage

import { SpeexEncoder, SpeexDecoder } from '@caitun/speex'

const encoder = await SpeexEncoder.create({
  sampleRate: 16000,
  quality: 8,
  complexity: 3
})

const pcm = new Float32Array(encoder.frameSize)
const frame = encoder.encode(pcm)
encoder.close()

const decoder = await SpeexDecoder.create({
  sampleRate: 16000
})

const decoded = decoder.decode(frame)
decoder.close()

If your bundler serves WASM assets from a custom location, pass locateFile:

const encoder = await SpeexEncoder.create({
  locateFile: (path) => `/assets/${path}`
})

Build

npm run build

build:wasm requires Emscripten emcc.
