Hi there,

Just a quick screenshot of my rktplayer music player (currently only flac support) based on the [racket-webview](https://pkgd.racket-lang.org/pkgn/package/racket-webview) / [racket-sound](https://pkgd.racket-lang.org/pkgn/package/racket-sound) module I developed.

The rktplayer repository [can be found here](https://git.dijkewijk.nl/hans/rktplayer).

This is interesting to see!

The gui uses html / css / javascript.  
Everything else model / database / controls are in Racket.

Thanks for your nice comment 🙂.

- The GUI "backend" is based on Qt WebEngine.

But racket provides most other things:

- The racket [web server framework](https://docs.racket-lang.org/web-server/index.html).
- SSL/TLS security based on self signed certificates (module [racket-self-signed-cert](https://pkgd.racket-lang.org/pkgn/package/racket-self-signed-cert))
- The [xml module](https://docs.racket-lang.org/xml/index.html) for html generation (i.e. xexpr-\>string)
- Got some syntax defined for javascript generation (see private/js-transform.rkt in racket-webview)
- I created module [simple-log](https://pkgd.racket-lang.org/pkgn/package/simple-log) to have a simpler form of logging in racket.
- And a [keystore](https://pkgd.racket-lang.org/pkgn/package/keystore) is used to store playlists of the rktplayer.
- [racket-sound](https://pkgd.racket-lang.org/pkgn/package/racket-sound) currently integrates a [small C library](https://git.dijkewijk.nl/hans/racket-sound-lib) based on [libao](https://xiph.org/ao/) next to [libflac](https://xiph.org/flac/) and [taglib version 2.x](https://taglib.org/).

There's a lot of work left. I'll probably be working on racket-sound to have a more consistent and abstracted interface to read music. I'll be integrating mpg123 the coming months. .

So I'm standing on the shoulders of giants here.

I changed package name 'racket-sound' to 'racket-audio'. Seemed more to the point.
