SÁGORA is a free and free software, designed by artists / researchers from the University School of Arts of the National University of Quilmes, Argentina.

It allows multiple users to connect in a virtual room and transmit audio in real time without canceling the signals, as happens in the platforms commonly used for teleconferencing. This particularity makes it an extremely useful application for musical practice, both in the cultural industries and education sectors, since it allows rehearsals and / or concerts using the internet.

SÁGORA is developed in C ++ and works with socket technology to send and receive audio information. It has the ability to match the different latencies of all the people connected, ensuring that the signals arrive at the same time and there is no sense of delay between the signals. It allows you to create rooms or connect to rooms, from where you can listen to the different participants, sharing the same sound space. The rooms have a code that makes access restricted.

For the design and development of SÁGORA, an environment that favors research and interdisciplinarity was needed, such as the National University of Quilmes (UNQ). In the particular case of these artists / researchers you can even find a crossroads and collaboration between different research projects. Dr. Esteban Calcagno is Director of the Bachelor of Music and Technology at the UNQ and of one of the projects to promote research on institutional strategic issues (PITEI), created at the UNQ at the end of 2018. This project is called “Platform of services for digital education” and its purpose is to create a platform and applications for online education. For his part, Lic. Diego Romero Mascaró is Director of the UNQ University School of Arts, a member of the PITEI “Platform of services for digital education” and co-director of the research project “Technological developments applied to the arts” , which is also integrated, among other researchers and scholarship holders, by Lic. Nicolás Rodríguez Altieri, a member of the SÁGORA team.
