Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

LiveKit Noise Cancellation Plugin for Node.js

This package provides noise cancellation capabilities for LiveKit Node.js applications.

Installation

npm install @livekit/noise-cancellation-node

Usage

import * as LivekitNC from '@livekit/noise-cancellation-node';

// Create AudioStream with noise cancellation
const stream = new AudioStream(track, { noiseCancellation: LivekitNC.NoiseCancellation() });

Options

  • NoiseCancellationC(): Standard noise cancellation
  • BackgroundVoiceCancellation(): Voice enhancement (background voice cancellation)
  • TelephonyBackgroundVoiceCancellation(): Voice enhancement (background voice cancellation) for Telephony audio

Architecture

This package uses a multi-package architecture to support platform-specific shared libraries:

  • @livekit/noise-cancellation-node - Main package with TypeScript code
  • @livekit/noise-cancellation-darwin-arm64 - macOS ARM64 binaries and resources
  • @livekit/noise-cancellation-darwin-x64 - macOS x64 binaries and resources
  • @livekit/noise-cancellation-linux-x64 - Linux x64 binaries and resources
  • @livekit/noise-cancellation-linux-arm64 - Linux ARM64 binaries and resources
  • @livekit/noise-cancellation-win32-x64 - Windows x64 binaries and resources

The main package automatically selects and loads the appropriate platform-specific package for your system.

Notes

If you experience crashes when using noise_cancellation (especially on AMD CPUs), it may be due to a failure in OpenBLAS's CPU detection. Manually setting the OPENBLAS_CORETYPE environment variable to a more conservative value (e.g., Haswell) may resolve the issue.
