Pirocast

Transform your Raspberry Pi into an autonomous radio receiver!

This piece of software allows you to use your Raspberry Pi as a radio receiver and/or simple audio player!
Pirocast is inspired by typical car radio systems. It can be operated with just 3 buttons and an I2C LCD display.

Features

• Easy to setup and use.
  All you need is Java and GnuRadio installed!
• Configurable
  You can configure almos everything! From time and date formats, labels, default and allowed settings, to bands, sources and logging
• Support for various audio sources:
  • Live radio (SDR required)
    Listen to your local FM radio stations.
    Supports FM, AM and Narrowband FM modulations.
    Also supports RDS (powered by gr-rds) with station name, radiotext, Traffic Announcement and Traffic Programme.
    Supports APRS decoding for narrowband FM via Direwolf.
  • Internet radio
    Stream music directly from your favourite internet radio stations. Supports most major audio formats (via ffmpeg)
  • Local files
    Pirocast can scan audio files in configured directories and play them. Supports most major audio formats.
  • AUX
    If you have an audio input in your Raspberry Pi, you can loop it back to output with Pirocast's AUX source.
• Extensible
  The source code can be easily tweaked to add new features, such as new audio sources, modulations, etc.
