STCode

STCode is a simple stereo encoder for FM, it uses pasimple and math to: - Calculate mono signal from s16le ((L+R)/2) - Generate the stereo pilot in phase to the stereo subcarrier - Generate the stereo diffrence signal using DSB-SC All that in about 3.5% cpu usage on a RPI-5 (lpf makes it 10, but stereo tool has 3 threads which do 100% cpu usage anyway, one 200)!
