Play radio. Style your App.
Project description
Eisenradio - a Web radio expandable collection
Overview
This repository shows the source code of an SVG animated radio show. Routed flask endpoints on a SQLite database.
- First Inet Radio App that can run a Spectrum Analyser in a Browser (Feb,2022), have a look at the sketch below
- Images are created with Inkscape
- Advanced features for GhettoRecorder
Comic style animated internet radio
Inkscape animated SVG images are used everywhere in the app. Also for the background. JavaScript is the mover.
- Art director AnimationTimer Class controls timer for all artist and stuff appearance
- Airshow executive director moveRandomAngle() is using tangens function with no-go areas to minimize the "crash slot"
- Zeppelin grey scale SVG is colorized by random colors, plus color gradations ShadesOfColor Class

Audio
Audio spectrum is used to animate the colors of some SVG images. Master function getAverageVolume() calculates the audio volume level. This function was created by "franks laboratory", link in the Thank-you section at bottom.
PowerSwitch class can color an unlimited number of path elements. It has also methods to animate different colors for different audio dynamic levels. Input for PowerSwitch class is delivered by powerLevelAnimation().
Classic and Ambient 🟦🟩 music will often show other colors than Thrash Metal or Hip Hop 🟧🟥.
PowerSwitch class can also translate list pattern into flashing lights.
let flashAni = new PowerSwitch({path: document.querySelectorAll("#z1PositionLights path"),
flashPatternList: [0,0,0,0,1,1,1,1,0,0,0,0,1,1,0,0,1,1],
flashPatternMultiplier: 20});
Have a look at both speakers (color) or the zeppelin (flash).
The "scaling by rhythm" of frontman Tux or friends 🐻❄️ is also driven by
⚡ Spectrum Analyzer
Choose between different spectrum analyzer shows. Analyzer frame is detachable. Put it where you want.

Energy Saver
Fun reduction option. Some browser and mobiles may be a bit overwhelmed by the fully animated show.
Switch off the most CPU hungry animations.
Tools menu
Here you find tools to enable and maintain blacklists. Configure animations, enable database dump or import a GhettoRecorder GitHub settings.ini file to database to add more radio station URLs.

Shuffled Playlists
You find this option in the secondary menu under the on top teaser image.
Play your local audio files in the browser. Folders are used as playlists.
Bring your earbuds to the limit. EisenRadio has a Volume Gain slider as well as GhettoRecorder. Pushes the preamp up to 300%.
Organize
Use the menu bar. About offers a help menu. Organize your web radios. Delete or update, backup and restore your radio stations.

Eisenradio - the boring details
-
REST API app on blueprints and ApplicationFactory of the Flask microframework with a SQLite database
-
First Internet Radio App that can run a Spectrum Analyser in a Web browser (Feb,2022)
-
A local Python Flask Web Server connects to the radio server in behalf of you. Your browser connects to Flask
- Backend (server) opens the connection, buffers the radio stream and presents it to localhost IP: 127.0.0.1
- Frontend (browser) controls the backend, plays internet and local audio playlists
- Browser audio element connects
http://localhost:5050/sound/classic
that streamshttp://37.251.146.169:8000/streamHD
- Closing the browser does not disconnect the server listen (buffer discarded) nor streaming connections
-
Plays and repairs aac plus files; play (1.3), repairs since version (1.4);
-
Backup and restore are easy work with the help of an optional ex/imported human-readable *ini file
-
Blacklist feature for recorded files (titles); delete only once
- lists can be ex/imported via a json dictionary file to other devices
-
playing local audio uses the web server multiple file upload feature
-
Multithreading allows you an unlimited number of radio connections at the same time, until the ISP Bandwidth limit hits
-
Android APK Package uses Python Kivy for multi touch and promotes the app to "foreground service" (to not get killed)

Contributions
Pull requests are welcome. If you want to make a major change, open an issue first to have a short discuss.
Next level could be Blender 3D objects rendered as 2D SVG in JavaScript motion. Sprite technique with images from 3D. Perhaps a moving ship or a flying saucer?
Thank you
