 Hey, it's Amfa. Today I want to show you a different kind of tool. It's not necessarily music related but it's a very useful thing to send audio from one jack server to another over a local network. Introducing ZetaNG Bridge or Zeta Network Jack Bridge. Yeah so for example right now I'm playing back this video from Olive Video Editor which uses Pulse Audio on my laptop and the Pulse Audio from my laptop sends to the network which goes to my desktop which goes to the audio interface connected over USB which goes to the monitors but it feels like it's connected directly to my laptop so it's not. But Amfa Pulse Audio has a network function on its own. Why don't you use that? Yeah yeah I hear you but this is not about Pulse Audio. It's about Jack! So what is ZetaNG Bridge? Well it's simple. It's a pair of programs one called Zeta J2N, Jack to Network and Zeta N2J, Network to Jack. These two programs allow you to send audio from one computer to another over a local network. In theory only through a cable and only for a local network but in practice I'm doing this over Wi-Fi and possibly you could also do it over the internet. So you'd probably need way bigger latency and fast networks for it to make it actually work. Man, slow down. I don't understand what you're doing. Like can you just start over and show me step-by-step how did you connect these two? Here I have T-Max which is a terminal multiplexer so I have SSHed into my desktop computer which is over there from my laptop and here is a local console on my laptop. So first I've run Zeta N2J on my desktop giving it the local IP address and an arbitrary port number I've chosen 9999. I've run it. It's waiting for the information packet and then I've run this command on my laptop Zeta Jack to Network IP address of the desktop PC the same as here and again the same arbitrary port number 9999. I've run that and the Zeta network to Jack on my desktop has received the connection from my laptop you see this is the IP of my laptop it's two-channel audio 48 kilohertz and now I can just you know place something on my laptop and as you can see there is no USB connection to this interface from my laptop but the audio is coming from the laptop this is not a remote session this is a local desktop it's going through the Wi-Fi to this box here which is connected for a cable to my PC and that PC is connected to the network to the audio interface which is connected to the monitors and you have audio from the laptop on the desktop and I must tell you the latency is freaking I don't notice it it's like it feels like it's just connected like the net the audio interface connected directly to my laptop which is not the case it's it's going through Wi-Fi not even a cable network I would probably get better results if I connected this through an ethernet port which I can do that's not a problem and I had some dropouts through the Wi-Fi network but that's to be expected I could increase the buffer there is an additional buffer if you read the manual which you always should do and I did and the manual that says you can define an additional yeah let's record you can define an additional buffer time and that buffer will help you with fuzzy network set up for example over Wi-Fi some packets might get lost if they arrive too late there will be have to be ignored but if you add an additional buffer time you will be able to overcome an unstable network connection which might be Wi-Fi it might be over the internet I don't have a way to test this over the wide area network but I would be really interested to see how it works you can also set it by default it transmits 24-bit samples so it's not the full fidelity because by default Jack runs at 32-bit float and it can also I think it can run at 64 no I think it on no no it can't but you can also transmit 16-bit integer so that's CD audio quality for something like you know playing back music on a remote machine you don't really need anything more and it will save you some throughput it's called bandwidth some so you're gonna get better better transmission less dropouts over Wi-Fi etc so yeah that's an interesting tool I've learned this actually I figured out this exists during somoi when another presenter has shown how to use that to create a network set up for for sending music to your to your amplifiers etc and what happens is it goes out to a an instance of Zeta JN J2N and now I'm like I'm rendering something on my desktop PC I can't use it to do anything else because all the RAM and all the CPU time is taken so I thought I'm gonna work on my laptop but I want to listen to music on these speakers and I don't want to disconnect my other interface from the desktop so I figured I'm gonna use Zeta network to Jack bridge works awesome anyway I hope you find this interesting and potentially useful in your work that's it thanks for watching I also want to thank all the people who support my work financially on patreon if you'd like to join them and help keep this show going please go to patreon.com slash ANFA or liberapay.com slash ANFA now go and make some music possibly sending it over a network bye ah dropout
