documentation of pcm output from -a

[zerog2k]

readme says:

./rtl_433 -a file_name will save the demodulated signal in a file. The format of the file is >48kHz 16 bit samples.

However, when i open this up in something like audacity and import it as raw pcm at 48000, it plays way to slow, compared to listening to the noise on am receiver (or through gqrx in am demod, etc)

Is it actually stored raw at whatever sample rate, e.g., 250000, that it was captured at?

Yes 250000 Hz. Audacity is mostly used for visualization.
