The puredata Raspberry Pi patch requires a microphone input, such as a USB microphone. The default input can be modified as follows:
nano /.pdsettings
When not using a Raspberryi Pi, it is possible to simulate the WiFi input with wifi.py.
pip3 install oscpy
git clone https://github.com/Maximaaal/Etherscape.git
cd Etherscape
python3 wifi.py
