Node. js allows developers to use JavaScript both on the client-side and the server-side, providing a unified language and ecosystem. This eliminates the need for context switching and enables code reuse between the front-end and back-end.

To stream audio and video files in Node. js, you can use the http and fs modules to create a simple HTTP server and read the file from the file system, respectively. You can also use the fluent-ffmpeg library to convert the file to a format that is compatible with streaming and pipe it to the response. console.

You can upload any audio file to your product environment, convert the audio file format, extract audio from videos and transform them on delivery. Audio files are uploaded to Cloudinary as a video asset type.
