@mymusictaste/async-audiorecorder

Requirements

• Node.js version 16 or later
• sox or arecord installed and available
  • To install sox on macOS, run brew install sox
  • For Windows, please search the web for installation instructions.

What is @mymusictaste/async-audiorecorder?

• This package extends the node-audiorecorder module with an awaitable promise.
• It inherits the same caveats as node-audiorecorder: it requires sox, rec, or arecord to be installed.
• It automatically injects sensible defaults for the program and audio driver based on the platform (Windows, macOS, or Linux).
• It adds a function to list available audio devices (best effort only!).
  • Uses rec on macOS and Windows, and arecord on Linux.
  • On Linux, it returns in plughw: format. You can replace it with hw: on the fly if necessary.
• Please let me know if it doesn't work on your system.

Why use @mymusictaste/async-audiorecorder?

• node-audiorecorder was good enough, but this package provides an await and TypeScript-friendly version of it.
• You can easily await for recorder.promise() to get the audio buffer reliably.

Example usage

import AudioRecorder from "@mymusictaste/async-audiorecorder";

// ...
const list = await AudioRecorder.availableDevices(); // Returns { device: string, label: string }. Use `device`!
const buffer = await recorder.promise();
