In this disconnected time, C4, like many other groups, is looking for new avenues for performance that do not require being in the same room at the same time. We are investigating different approaches: serial overdubbing, simultaneous performance using the Internet to connect performers, and so on. We plan to pursue all approaches to see what we can gain from each.
This document focuses on one approach: high-quality live remote music performance, with many participants connecting from different places via the Internet and performing in real-time. This approach is different from some other (equally valid) approaches that we and others are also pursuing.
In short, we are aiming at a performance that is both live and high quality. Getting to this combination requires surmounting some obstacles.
So far, the best audio sharing solution for us appears to be Jamulus, an open source platform for remote music-making. It was originally designed more for rock music jamming, but it works well for our use case.
The next section is a quick setup checklist. The following sections cover in more depth the important considerations involved in high-quality live remote music-making:
Finally, there are sections covering advanced topics, for those interested in a more involved audio setup.
For an overview of many of the topics covered here, you can also watch "All Together Now - Live Remote Choral Performance in the Age of Social Distancing," a webinar cohosted by C4 members Karen Siegel, Daniel Andor-Ardó, and Brian Mountford, and Scot Hanna-Weir, director of choral activities at Santa Clara University.
