How to convert raw_audio.cf32 to wav using tools like ffmpeg, sox &friends?
I need to process many “raw_audio_recording.cf32” files generated by RTLSDR-Airband
into a training dataset for an STT model.
I don’t use any SDR hardware myself and haven’t installed RTLSDR-Airband either.
The signal in question is AM ATC air traffic radio.
How should I go about this on ubuntu linux?

raw_audio.cf32 files are the filtered and down-sampled I/Q samples that feed into the demodulator. you could demodulate them to get WAV audio, but you would be better off outputting MP3 files and using ffpeg to convert them to WAV
