Hi, I don’t understand how to convert .ogg audio data that can be downloaded from the observations into complex IQ data.
Could you please explain which is the format?
For example I know that if I save a .wav file from gqrx setting “Raw IQ” for the demodulator I get a .wav file with two channels representing the I and Q branch (I obtain a Nx2 matrix if I open it in MATLAB).
In MATLAB .ogg files instead yield only one channel (Nx1 matrix); I tried to read it like if the format was interlaced IQIQ samples, but it didn’t seem to work.
I’m doing something wrong?
