Music blared from loudspeakers. 廣播喇叭裡響起音樂聲。
For an electroacoustic composer, the fixed and artificial space of loudspeaker diffusion is the domain in which music is usually imagined.
It was found that the horizontal panning was performed successfully, but two loudspeakers above the listener were not enough.
As a moderate crowd of theatregoers gathered, the performers started to roll huge empty barrels, while punk music blared from loudspeakers.
Auditory stimuli were presented through a loudspeaker concealed below the monitors.
In this example, the width of the spatial illusion is strongly linked to the position of the loudspeakers in the listening space.
Spatial information in acousmatic music has previously been confined to the stereo or diffused sound field, or to the use of loudspeakers as point sources.
In both these works, small speakers are mounted on walls in plant-like configurations with the loudspeaker wires resembling stalks.
This kind of constrained randomness allowed the creation of characteristic movements without defining explicitly every single transition between loudspeaker constellations.
