Introduction to 迴,
ᏗᎷᏰᎥᎥᏋᏁᏖ Music,
and Sound Technology
Research on the mysterious entity known as "Hui" (迴) has lurked behind the soundscape studies proposed by scholars since the 1960s and later by musicians in their approach to environmental music. Although we have continued to study the subject without the public's knowledge, the complex ecology and technological limitations of "Hui" have prevented us from unraveling the many mysteries surrounding the entities, and have left us foggy in our research. Over the past year, we have been collecting and organizing old research materials and thanks to today's advanced digital technology and environment, we have been able to conduct new research. We plan to archive all kinds of data, including research materials, history, and field recordings, on this site.

The "迴" is an acoustic-based creature that manifests itself between the realms of reality and the digital domain. Devoid of any physical form, the "迴" is a being that assimilates sound debris from physical space and captures "sound objects" floating in cyberspace to construct its own ethereal body structure. Due to its existence in a distinct realm and possessing a unique form, humans cannot perceive or recognize the "迴" on their own. Nevertheless, a text describing the study of "迴" at the dawn of the 20th century mentioned that a scant number of individuals with clairaudience displayed an ability to perceive the presence of "迴 partially." These early "clairaudience" researchers likely formed part of a select group.
Before the advent of the electric age and the proliferation of digital technology, systematic research on clairaudience was challenging to establish. Consequently, clairaudience was primarily regarded as a psychic ability, a phenomenon of the supernatural, or even interpreted as the divine voice of God.

The footprints of the "迴" can be traced back more than a thousand years, but the methods for recording them were limited during that period. Before the advent of sound recording technology, the primary sources of information were ancient murals, carvings, and oral folk legends, with the visual aspects often supplemented by imagination. These artifacts are referred to as "relics."
