What do people say when given an opportunity to speak on the radio for two-seconds?
They count. They list the names of cheeses. And they play instruments and sing.
We know this because of Hear-Here, a crowdsourced, crowd-directed electronic space where anything goes, as long as you can say it, sing it or play it in two seconds. During broadcasts/recording sessions, anyone who wishes to participate simply has to load a web page, wait for their turn and then start making sound.
August Black, technologist-in-residence at the University of Colorado Boulder鈥檚 ATLAS Institute, developed the application that allows multiple users from remote locations to input live sound from their browsers to an FM station and a live streaming audio feed. He presented his research during the聽聽conference in London, August 23鈥�26.
鈥淧eople are used to just listening to the radio,鈥� says Black, who has a PhD in Media Arts & Technology from University of California, Santa Barbara. 鈥淲ith Hear-Here, anyone can contribute. They are not just being consumers.鈥�
Hear-Here鈥檚 novelty lies in its simplicity and its direct overlapping of radio and Internet methodologies, says Black, who developed the initial prototype in 2015 during a 10-day聽聽residency, where artists experiment with broadcast media and the airwaves.
The system connects users in a browser-based, peer-to-peer network using WebRTC, a free, open source project that provides browsers and mobile applications with Real-Time Communications capabilities. A master server collects the input from participants and broadcasts it live on FM radio and online.聽
Anyone who wants to participate simply accesses a webpage that shows the number of current participants and their own position in the line-up. 聽When it鈥檚 their turn, they have two seconds of air time.
Black, who began his academic career in sculpture and painting at Syracuse University, became interested in the intersection of radio and the Internet in 1996 while interning with the National Radio of Austria鈥檚 art-radio program. At the time the Internet was in its infancy, but the Ars Acustica Experts group of the European Broadcast Union built radio infrastructure to broadcast radio events simultaneously in different parts of Europe.
In 1998, Black wrote streaming software that allowed him to broadcast his live radio program simultaneously on the聽, including from an underwater location in the historic city center of Linz, Austria. At the time, most people did not have access to the Internet and data speeds were too slow for listeners to interact, but it was novel to overlap the Internet with radio, he said.
In 2002, Black developed software for a聽聽so users could upload and mix audio together simultaneously online while being on air. Recent Internet advances in web sockets, which allow users to send requests and respond back and forth, and WebRTC, which allows browsers to send audio, video and data without a server, made Hear-Here possible, he says.
鈥淭he two seconds creates an environment in the same way a speed bump defines speed on the road, or a fence delineates space in a city,鈥� he says.
Black plans to do further research with Hear-Here, including reducing the time between turns to nanoseconds so voices overlap, and increasing speaking time so participants have the opportunity to say entire phrases.
鈥淭he interesting part about making art on the radio is that you don鈥檛 see your audience and are speaking to everyday folks鈥攖hey could be truck drivers or people cooking in the kitchen,鈥� Black says. 鈥淭he end result can be very surprising.鈥�
