Compile

gcc -Ofast -c demod_base.c
gcc -O2 -c bch_ecc_mod.c
gcc -O2 -c rs41base.c
gcc -O2 -c dfm09base.c
gcc -O2 -c m10base.c

Usage/Examples

./rs_multi --rs41 <fq0> --dfm <fq1> --m10 <fq2> --lms <fq3> <iq_baseband.wav>
./rs_multi --rs41 <fq0> --dfm <fq1> --m10 <fq2> --lms <fq3> - <sr> <bs> <iq_baseband.raw>
where
     -0.5 < fq < 0.5: (relative) frequency, fq=freq/sr
     <sr>: sample rate
     <bs>=8,16,32: bits per (real) sample (u8, s16 or f32)
decodes up to MAX_FQ=5 (demod_base.h) signals. Decoding more signals than number of CPUs/cores is not recommended.
