How does a binaural microphone differ from a bionic one, what sound effects can you experience if you sit on a fire escape for a long time at night, and what is psychoacoustics? Where do the illusions that we can hear come from, and what wonders of technology do people come up with to record them? Musician and composer Tigran Paravyan, who faced these questions while studying at the Faculty of Sound Research at New York University, studies the possibilities and features of non-standard microphones and acoustics of different spaces. In the film, he travels to unusual places in Armenia, from medieval monasteries to abandoned concert halls, sings and captures songs and sounds of places using experimental sound recording methods.
