Hello, this seems to be the only place to ask for help. So I#m doing: I would like to use SoX for this scenario me speaking ----->  inbuild micrphone of my tablet (Windows 10) ---------->----------LAN------->---------second PC----->------soundcard---->----Amplifier------>Speaker ----> my words as *realtime* audio If I understand right I have to setup IP-adresses and ports. Is there somewhere a collection of batch-files or a parameterlists that show which parameters and options I have to use for this? best regards Stefan
