Hi
Perhaps you can add a simple performance test to rtl_fm.
"decoding 100000 samples takes xxx ms" or something like that.
It helps to compare different CPU and OS families.

Hi and thanks for a great tool set.
I've implemented a faster FM demodulator for rlt_fm. Its an
instantaneous frequency demodulator, like the already implemented atan
method, but it uses some math tricks to get rid of the the actual atan
calculation. Feel free to use it if you wish
Nice, thank you.
It should probably be under the -A option with all the other types of
FM demodulator math. Maybe benchmark it against the other FM
demodulators, "-A fast" or "-A lut". The default "-A std"
was not
designed to be very quick, just accurate. Being faster than "-A std"
is not very difficult.
Let me see if I can get a fixed-point version written.
