This project is aimed at providing an extendable soundmodem backend to various java applications. It is now in its initial phase providing nothing but a simple AFSK1200 modulator and rudimentary support for building AX.25 UI Frames needed for APRS. It is a rewrite/spinoff of the publicly available linux soundmodem which is written in C/C++
Welcome to jsoundmodem,
this project was set up to enable APRSDroid to communicate via transceivers.
Therefore it is still very limited right now.
Working features:
- Afsk modulator
- APRSFrame packet builder
- generic Message class to store not byte-aligned messages and their
length in bits. (Being unaligned is a painful property of messages
after being bit stuffed
Next to come:
- I'm thinking of an Afsk demodulator
- Extending the APRSFrame packet builder to a generic APRS packet
handler
