M17_RF_streamgen

Generates an M17 RF stream for Codec2-encoded speech files ('c2enc' output).

M17_RF_streamgen.c - main program. Just a sketch right now.

dummy.c - can generate a pseudorandom bitstream with legitimate sync patterns. This can be used to check receivers.

Installation

make

Nomenclature

Example

This example records local audio and generates a M17-compliant RF stream into a file. Codec2 and SoX need to be installed.
