A Python library to generate EAS SAME Audio using Raw Data - Remastered
EASGen is a powerful Python library for translating EAS (Emergency Alert System) ZCZC strings or other data into SAME (Specific Area Messaging) headers. It includes robust support for individual headers, attention tones, EOM generation, emulation modes, and WEA tone generation, ensuring a seamless experience for encoding emergency messages.

- None
- TFT (Resample to 8KHZ using ".set_frame_rate(8000)" on the generated alert)
- EASyCAP (Basically the same as None)
- DASDEC (Crank up the Samplerate to 48000 for this one)
- SAGE EAS ENDEC (Mode = "SAGE")
- SAGE DIGITAL ENDEC (Mode = "DIGITAL")
- Trilithic EASyPLUS/CAST/IPTV (Mode = "TRILITHIC")
- NWS (Mode = "NWS", Resample to 11KHZ using ".set_frame_rate(11025)" on the generated alert)
- HollyAnne Units (Can't sample down to 5KHz... This is a good thing.)
- Gorman-Reidlich Units (Don't listen to them enough to simulate. I think they're like TFT, but donno.)
- Cadco Twister Units (No Data)
- MTS Units (No Data)
