Quiet.js is a JavaScript binding for libquiet, a library that transmits and receives data via sound using a sound card, either through speakers (near-ultrasonic around 19kHz) or cable (3.5mm, 40+ kbps). It ships a libquiet binary compiled with emscripten so it runs in browsers via the Web Audio API.

Use cases

• send data between devices using sound
• transmit data ultrasonically from the browser
• transfer data over a 3.5mm audio cable
• build a browser-based acoustic modem
• exchange small payloads between phones via audio
• data-over-sound communication in JavaScript

When to choose

• you need to move data between devices acoustically with no network
• you want near-imperceptible ultrasonic data transmission in a web app
• you need wired audio-cable data transfer at ~40 kbps in Chrome/Edge

When to avoid

• you need Safari or iOS reception (microphone input unsupported)
• you need ultrasonic reception in Firefox (32kHz resampling limit)
• you need high-bandwidth or reliable long-range transfer
• you need a maintained project - the last release was 2021
