Post script after recording?

1

Hey.

I don’t understand the whole workflow of the SatNOGS thingy. Where can I put a new/-nother script after the audio is recorded? I want to try to implement wxtoimg for NOAA pictures.

I need a resampler to reduce the wider NOAA FM audio to a 44kHz audio that would be needed for wxtoimg.

Possible?

Hi,

for resampling you can use sox:

sox infile.wav outfile.wav rate 11025 gain -6
The “gain -6” reduces volume by 6dB, because the level may be to high
for wxtoimg otherwise.
wxtoimg can only use wavs with 11025Hz samling rate.

manpage:

AUDIO INPUT FORMATS
Audio  input files may be in either AU (.au), WAVE (.wav), or raw (8-bit unsigned or 
16-bit signed LSB) format.  The files must be encoded
in linear PCM format at 11025 samples per second.
