# RTL-FM DECODING - (Baselining of existing decode performance)
|

# NOTE: This requires tsrc (from codec2-dev/unittest) and Viproz's hacked rtl_fm to work.
|
|
# Viproz's rtl_fm is available from here: https://github.com/Viproz/rtl-sdr/
|
|
# Build this, but do NOT install it. Instead, copy the rtl_fm from build/src to the *this* directory, and re-name it to rtl_fm_stdin
|
|
# You still need a RTLSDR connected to be able to run this.
|
|
#
|
|
# tsrc is available at http://svn.code.sf.net/p/freetel/code/codec2-dev/misc/tsrc.c
|
|
# HOWEVER there is a bug which makes it neglect the -c (complex) option.
|
|
# Change line 59 to read: int channels = 2;
|
|
# and compile with gcc tsrc.c -o tsrc -lm -lsamplerate
|
|
# Then copy this file to *this* directory.
|
|
#
|
|
# The decoder commands for these are generated based on the rtl_fm output sample rate.
|
|
# The input samples, which are in complex float IQ format, are shifted in frequency to where rtl_fm
|

# expects them to be, and are also resampled to match rtl_fm's desired input rate.
