What is JackTrip?<\/h1>\n

The people best equipped to tell you about JackTrip are the creators at Stanford University: https:\/\/ccrma.stanford.edu\/docs\/common\/JackTrip.html<\/a><\/p>\n

But basically, the title is pretty apropos. JackTrip allows you to make a (relatively) direct connection between users
\nwithout the overhead of middlemen servers or special processing.<\/p>\n

JackTrip runs on top of JACK, which stands for Jack Audio Connection Kit. What JACK does, among other things, is to
\nallow you to pipe audio around different software.<\/p>\n

*Warning* For best results don’t do this with WiFi. It might work, but it might buzz a lot, and
\n then you have to increase the latency, which makes it less instantaneous.<\/p>\n

Less dire warning: This post has a lot of information to understand if you’re just reading it, but I promise if you go
\nthrough and follow it step by step, you won’t have any problems. And it’s mostly repeated twice for differences between
\nWindows and Mac.<\/p>\n

Before you read on, even though Important Notes<\/a> are at the end, I would read through them first,
\nignoring things you don’t understand, but keeping in mind things you do.<\/p>\n

    Get Set Up<\/h1>\n

    If you’re hosting, then read this part. If you’re running the client, you can skip to “Installing Jack.”<\/a> It doesn’t really matter who’s server and who’s client, but one person
    \nhas to be the server, preferably the one who knows how to forward their firewall ports.<\/p>\n

    Opening Ports and Finding Public IP: Hosts Only<\/h2>\n

    JackTrip by default uses UDP port 4464 for quick communication. If you know what this means and how to get your ports
    \nopen, skip this section. If not, read on.<\/p>\n

    This is the most difficult section to write, because opening ports depends on what router, internet provider, and
    \noperating system you have. The unfortunate thing is that this means you probably won’t be able to JackTrip behind a
    \nschool or office network.<\/p>\n

    Finding your local IP and Gateway address<\/h3>\n

    You’re most likely behind a router. You’ll need to find both the local IP address of your computer and of the router.
    \nWe’re looking for IP addresses that are in the range of<\/p>\n
