STCode
STCode is a simple stereo encoder for FM, it uses pasimple and math to:
- Calculate mono signal ((L+R)/2)
- Generate the stereo pilot in phase to the stereo subcarrier
- Generate the stereo diffrence signal using DSB-SC ((L-R)/2)
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)!
