transmit data over sound

setup

after cloning this repository, is recommended to create a virtual environment to install the needed packages:
python3 -m venv venv
on mac/linux:
source venv/bin/activate
on windows:
venv\Scripts\activate
now you can install the requirements:
python3 -m pip install -r requirements.txt

transmit data

edit the line 9 of transmissor.py file, replacing the string that you want to transmit:
payload = b"Hello World!"
and run transmissor.py, it will generate the noise of data, you can record it externally

decode data

run receptor.py, it will stay hearing the built in microphone and decode all heared data
