## SolutionListening to the wav file it sounds like modem tones. We can use a tool like `minimodem` to decode these tones. We can try different baud rates until one produces a result:
```shell$ minimodem --read 300 -f tx.wav### CARRIER 300 @ 1250.0 Hz ###flag{our_technology_is_immaculate}
### NOCARRIER ndata=35 confidence=2.414 ampl=0.992 bps=300.00 (rate perfect) ###```
