python modem is a tool for converting digital data into sound waves using various modulations. this tool also makes it possible to demodulate this data back into a binary form
in addition, it can also analyze modulated and demodulated sound waves and present them in a user-friendly graphic form
this program can also be used as a chatbot working via terminal or rest api
| Modulation Type | implemented | Max reliable baudrate |
|---|---|---|
| ASK | ✅YES | 2000bps |
| 4-ASK | ❌NO | N/A |
| FSK | ❌NO | N/A |
| BPSK | ❌NO | N/A |
| QPSK | ❌NO | N/A |

modulate data given in parameters into sound wave using ASK modulation
python3 main.py modulate -m ASK --i "abcdefg" -o "<path>.wav"
modulate data given in parameters into sound wave using ASK modulation and play it
python3 main.py modulate -m ASK --i "abcdefg" -o "<path>.wav" -p
demodulate sound file using ASk demodulation and save its output to text file
python3 main.py demodulate -m ASK --i "<path>.wav" -o "<path>"
