audiospy

Simple cross-platform client-server program which records audio data from microphone on one PC and plays it in real-time on another PC. It consumes very small amount of system resources: it can run 24/7 without any CPU usage unless the client is connected. When the client is connected the server's CPU usage is very low.

Run

1. Start the server which listens on TCP port 64000

    ./audiospy_sv 64000
   

   This process records from the default audio device and transfers the data to any connected client.

2. Start the client which connects to the server with IP address 127.0.0.1 and TCP port 64000

    ./audiospy_cl 127.0.0.1 64000
   

   After a successful connection this process receives the audio data from the server and plays it via the default audio device.
