Eisenradio - Web radio DB / Media-playerOverviewThis repository shows the full stack source code of an SVG animated GUI forGhettoRecorder.first internet Radio App that can run a Spectrum Analyser in a Browser (Feb,2022), sketch at page bottomSVG animations in vanilla JavaScript super fast animated and colorized with regexPlaylist feature; load and walk through a list of your local sound filesREST API Flask endpoints; serve a SQLite database in plain SQLdeployment source code forAndroid Studio,Docker,SnapcraftandKivyavailableNameThe initial design was intended to mimic a hardware store site with multiple items listed.
"Eisen" Hardware [iron radios].Comic style animated internet radioInkscape created SVG images are used everywhere in the app. No raster graphics in this project. Except converted from SVG.90% of the SVG animations run on canvas for reduced CPU load and smooth, up-scaled displaya dedicated multi SVG image and SVG group loader class to preload all SVG stuff as super correct tagged SVG imagesinline SVG groups are loaded into a dictionary of image instances and connected to their canvaseach instance stores the image, a list of its SVG tags as well as the current transformation status and position, ...SVG path manipulation method with regexThe functional principle can be transferred to Java on Android to create dynamic 2D game backgrounds.AudioAudio spectrum is used to animate the colors of the speaker symbol waves.
Speaker symbol shows customized colors for different levels of audio output strength and dynamic.
Unfortunately the display is very CPU hungry. So only one speaker is shown.Classic and Ambient 🟦🟩 music will often show other colors than Thrash Metal or Hip Hop 🟧🟥.Master functiongetAverageVolume()calculates the audio volume level. This function was created by "franks laboratory", link in the Thank-you section at bottom.The "scaling by rhythm" of frontman Tux and friends 🐧 🐱 🐻 is also driven bygetAverageVolume()Local audio and shuffled playlistsA local folder with files of different sound file types is called a playlist.
AAC and MP3 files are known to run. You can go back and forth in the list.If AAC is hanging, you can repair the whole folder with "Tools/aacp file repair" menu.
Integrated from myaacRepairrepo.Remember, the app runs in a browser.
Wemisusethe upload multi select feature of the browser.
Nothing is uploaded, but fileobjectsare caught in a list and played.Gain - preampBring your earbuds to the limit.
EisenRadio owns aVolume Gainslider as well asGhettoRecorderPush the preamp to 300%. This feels like 20% louder.Works with bluetooth headphones!Spectrum AnalyzerSpectrum analyzer canvas is now fully integrated and can be switched by the "TV" button.
Choose between different spectrum analyzer shows.This concept can show its strengths if used to present the latest management reports.
A background video on canvas one and several statistics shown on separated, animated, or distorted monitors, canvas of course.Customized radio"Edit" the radio settings. Upload your favorite pictures to the database. Add a comment.The app page is separated by two areas.
A monitor to the left and a display area beside for pictures and comments or the playlist titles.Energy SaverSustainable fun reduction.
Some exotic browser and mobiles could be overwhelmed by the fully animated show.You are compensated by a CPU icon that can change its color.RecorderCalled and terminated GhettoRecorder threads for listen and record.This version suffers from the initial button press concept.
Next version of EisenRadio will use the latest GhettoRecorder for easy-peasy internal switching.Recorder blacklist featureEach recorder refuses to write a file, if the title was written to its radio specific blacklist before.One dedicated thread is responsible to update all radio blacklists.
All lists can be dumped into a JSON file and merged with GhettoRecorder blacklists. Uploaded to DB then.EisenRadio writes temporary lists of known recorded file names in JSON format.
The SQLite database is updated with a fresh file name only if a recorder writes a new file.

You can search through the project to see what is going wrong.ContributionsPull requests are welcome.
If you want to make a major change, open an issue first to have a short discuss.Next level could beBlender 3Dobjects rendered as 2D SVG in JavaScript motion.
Replace pure DOM element animation with canvas. Each animation gets its own canvas for more speed and to lower CPU.Thank youYouTube franks laboratoryLicenseMIT
