The sensation is ideally created in a live Aeolis concert taking place at a vivid outdoor environment, such as beach, a roadside, or a nature reserve. The soundscape – the totality of sounds existing in the scene – is captured by a microphone and used as the instrument’s input. The instrument is operated by MIDI to generate pitched tones like a standard synthesizer. Tone generation is achieved by way of subtractive synthesis, amplifying the harmonic series corresponding to the desired notes and attenuating all other frequencies. This results in tones that preserve the real-time sonic cues and characteristics of the soundscape. For instance, an exceptionally loud and reverberating breaking wave will produce an exceptionally loud and reverberating pitched tone, with only minimal latency. The tones are projected via loudspeakers, or live-streamed to the audience’s headphones.
