Play radio. Style your App.

Eisenradio - a Web radio expandable collection

• Freedom: Style your app with pictures, import a poem, song text, or a funny comment to have a good time
• Cool feature: Create a shuffled playlist within a local audio files folder in seconds
• More action: A ping variable shows the response time and a spectrum analyser the frequency range
• Speed: Travel through the app at breakneck speed, thanks to the smart design of the controls
• Android: download to mobile (link below .-apk), rename *WHL to *ZIP, extract with Android file manager
• https://pypi.org/project/eisenradio-apk/

Eisenradio - the boring details

• A REST API app on blueprints and application factory of the flask microframework with a SQLite database

• First Internet Radio App that can run a Spectrum Analyser in a Web browser (Feb,2022)

• browser can play local aac plus files in a playlist (from Eisenradio version 1.3)

• Eisenradio uses its own API and adjusts the buffer size for a given bit rate

• Backup and restore are easy work with the help of an optional exported, human-readable *ini file

• Eisenradio uses Pythons sys.path; it will find its modules on the dark side of the moon

• The Android APK Package uses Python Kivy for multi-touch and promotes the app to "foreground service" (not get killed)

• Backend (server) opens the connection, buffers the internet stream and presents it to localhost IP: 127.0.0.1

• Frontend (browser) controls the backend, plays internet and local audio and has a spectrum analyser at your disposal
