eisenradio 1.1.2

Play radio. Style your App.

Eisenradio - a Web radio expandable collection

• Organize your web radios; delete and update, backup and restore
• 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 runs a Spectrum Analyser in a Web Browser (Feb,2022)

• 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)

• Eisenradio app runs on one processor only; it uses Python Multithreading; Multiprocessing cannot fork on Windows (inherit context)

• 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

• Test: Kill browser - streams are up, browser reconnects; Kill terminal - stops all communications
