# Python RTL-SDR Playground
Just some tests with binding RTL-SDR to Python programs
## NumPy Demod
```bash
$ python numpy_fm_demod.py capture
$ aplay wbfm-mono-50000.0.raw -r 50000 -f S16_LE -t raw -c 1
```
Note that the final sample rate can never really be 44.1kHz.
Alternatively dump and load samples:
```bash
$ python numpy_fm_demod.py dump out.npy
$ python numpy_fm_demod.py load out.npy
$ aplay wbfm-mono-50000.0.raw -r 50000 -f S16_LE -t raw -c 1
```
