"""
Simple example of running birdnetlib in a TCP Server. To test the example:

Start the server in one terminal:

python simple_tcp_server.py

In a second terminal, send a Wav file to the server using netcat:

cat 2022-08-15-21-05-51.wav | nc -q 0 127.0.0.1 9988

If you have a sound card and microphone you can send a continuos stream of 10 second wavs using arecord:

arecord -r 48000 -f FLOAT_LE --max-file-time 10 | nc 127.0.0.1 9988

If you want to stream from somewhere other than the localhost,
change the TCPServer address from 127.0.0.1 to 0.0.0.0
