Jack Trip was a project born in, and curated by, Stamford University, addressing a problem of latency in communications. Choirs and orchestras sing and play together, which translates technically as being within 25 millisecconds of each other. Unfortunately, PCs are quite bad at that kind of focus, being busy checking emails, anti-virus and a thousand and one other things not conduicive to togetherness. In addition, internet signals sometimes follow some rather extensive paths, adding to the delay, which in general terms is called latency.
For this reason, a fairly cheap alternative was designed based around a barebones microprocessor called the Raspberry Pi, connected to a sound card to interface with microphones upstream, and a central computer hub known as a server, downstream. A choir will have a Jacktrip box in each house, using the normal internet connections to communicate with the server. Radio communications with your internet hub are disparaged, because they’re so slow: you’re going to have to run a wire to the box.
The microprocessor’s code is transferred from a PC, and is stand-alone, it does what it’s supposed to and nothing else. No turning the kettle on remotely at half time! The Raspberry Pi hardware is in constant evolution, as is the software, and a number of alternative sound cards have to be provided for, so there is a certain degree of imprecision as a result.
That being said, the project recognises that singers aren’t interested in becoming coders, and so a prebuilt box is available. It’s also possible to assemble or build your own.
