Node audio server

---

This project aims to create a server and client for serving audio between Node.js and browser.

API exposure

(more details soon)

• createPlaylist - method to create playlists, ie generate audio files and a .json manifest file). The .json file serves the same purpose as a DASH .mpd file or a HLS .m3u8 file.
• serveAudio - function to get audio chunks with a very basic cache layer
• startServer - Not implemented yet. A node.js server implementation to serve audio.
• player - Not implemented yet, work in progress. Client side player.

Where the project is at now:

Creating a prototype (PoC) player with some of the Roadmap functionality. WIP.

Roadmap:

• generate playlists with different bitrates from WAV files
• middleware to serve audio chunks
• test consuming sequential chunks using MSE api
• client side player with basic functionality (prototype)
  • load chunks on demand (no need to download all chunks if the player is paused)
  • show what parts are downloaded in the progress bar
  • enable seek
• enable encryption in server-client audio data (clear key)
• use different bitrates depending on network performance
• audio play tracking and more DRM analytics
• use flac and opus (currently only .mp4 container is implemented)
• client side player
  • in React
  • in Vue.js
  • vanilla js

How to contribute:

• feel free to reach out
• install, check the tests or check the dev-server with npm run dev and open localhost:3000 in your favorite browser
