It is also possible to navigate to the Netflix home page. Narr will then download audio tracks of trailers or previews.

How it works

Narr uses the Chrome DevTools Protocol to communicate with the browser. It intercepts the network requests and downloads the audio tracks in mp4 format. This is possible because the audio is not protected by DRM.

Build from source

Narr is written in Go. You can build it from source with the following commands:

git clone https://github.com/IljaN/narr.git
make build_all

This builds binaries for Linux, Windows and MacOS (amd64 + arm64) and places them in the bin directory.
