The Heart of the Research  \nAnnette Vande Gorne  \nThe spatial projection of music for acousmatic listening – the sound in space – enables the space of the future to open up to a fifth dimension of expression in music: the space of sound.  \nThe listening conditions of acousmatic music (with no real established sound source) approach those of a blind person, who senses space by close listening to the acoustic qualities of his or her physical environment. The ›eyes closed‹ approach abolishes the physical limits of the performance space, and it allows the imagination to deploy its spatial sensations.  \nSpecies of Spaces: The Four Main Spatial Categories  \nFour categories of space emerge from this particular practice of interpreta-tion and knowledge of the acousmatic repertoire: (1) the ›ambiophonic‹ or ›surround space‹ immerses the listener in a ›bath‹ of sound; as opposed to (2) the ›sound source‹ space, in which sounds may be localized; (3) the ›geometry space‹ in a work structures planesand volumes; and (4)›space illusion‹, works in the traditional stereo format. The first three categories relate mostly to multichannel recordings. In contrast, the fourth category, the traditional stereo form, creates both a phantom sound source (possibly moving) and an illusion of spatial depth across the distance of two loudspeakers, regardless of whether that depth is consciously perceived as such. This sonic image resembles a film that displays spatial depth in the central perspective format on a screen.  \n1a – Ambiophonic Space  \nA space is termed ambiophonic if we cannot determine where sounds come from, so that the auditor is bathed in a diffused ambiance. Listening achieves a ›mixing‹ of all events hinted at. One can draw an analogy to Byzantine churches: these include domes covered with gold tesserae, which redistribute what little ambient light there is equally across the whole church, but the source cannot be localized.  \nMusica/Tecnologia, 18 (2024), ISSN online 1974-0050, ISSN print 1974-0042, pp. 35-49 DOI: 10.36253/music_tec-15335 – [http://www.fupress.com/mt](http://www.fupress.com/mt)  \n© 2024 Firenze University Press e Fondazione Ezio Franceschini  \n36 Space, Sound, and Acousmatic Music. The Heart of the Research  \nFor ambiophonic diffusion, we surround the audience with identical speakers, relatively equidistant to each other, so that there is no acoustic ›hole‹. The encircling takes place in every plane; the sphere is the ideal model. If the audience is encircled on only one plane, then the circle be-comes the appropriate model. Dolby and THX cinema systems can also be classified in this category: three different channels at the screen but the sides and rears share one or two channels. The sound projection should be done with identical loudspeakers surrounding the audience. There should be only little movement realized with the aid of the console.  \n1b – Divided Space  \nUnlike general surround space, which favours the same type of sound positioned, with a few variations, on several loudspeakers, and spatialised in a unified global movement (like the octogris software), divided space allows a polyphony of different sounds and a superposition of diversified movements, in an encompassing and unified perception of space.  \nUnlike pointillism, spatial sources are not precisely heard. Space is globalised. It is, however, permeated by small internal movements that bring it to life and make it vibrate. It immerses the listener in multiplicity. It can be compared to flux, in the taxonomy of energy-movements.  \nThe dome projection instrument seems to be the best spatial configuration because it is associated with an envelopment (bath) of sound, and therefore ambiophonic in all dimensions, including height. The perception of auditory space in height is almost as precise as angular perception (the circle) . Spatial division is conditioned by the multiplication of output channels: 16 at least (8 and","cbCaip8omsxFmt2A","https://ap.wps.com/l/cbCaip8omsxFmt2A","pdf",326565,1,15,"English","en",105,"# Space, Sound, and Acousmatic Music\n## The Heart of the Research\n## Species of Spaces: The Four Main Spatial Categories\n## 1a – Ambiophonic Space\n## 1b – Divided Space\n## 2a – Source Space: Pointillism","[{\"question\":\"What does “spatial projection” mean in acousmatic listening?\",\"answer\":\"It refers to projecting sound into space so that the listener experiences the space of sound as part of musical expression.\"},{\"question\":\"How are the four main spatial categories defined?\",\"answer\":\"They include ambiophonic/surround space, sound-source space, geometry space, and space illusion in traditional stereo.\"},{\"question\":\"Why is source space compared to pointillism?\",\"answer\":\"Because it pinpoints the sound source with localization emphasized, using short, delineated attack transients so the listener can track individual speakers.\"}]","Space, Sound, and Acousmatic Music - The Heart of the Research | PDF",1787942768,23,{"code":4,"msg":31,"data":32},"ok",{"site_id":24,"language":23,"slug":33,"title":13,"keywords":34,"description":14,"schema_data":35,"social_meta":85,"head_meta":87,"extra_data":89,"updated_unix":28},"space-sound-and-acousmatic-music-the-heart-of-the-research","",{"@graph":36,"@context":84},[37,53,67],{"@type":38,"itemListElement":39},"BreadcrumbList",[40,44,47,50],{"item":41,"name":42,"@type":43,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":45,"name":46,"@type":43,"position":11},"https://docshare.wps.com/document/","Document",{"item":48,"name":12,"@type":43,"position":49},"https://docshare.wps.com/document/literature/",3,{"item":51,"name":13,"@type":43,"position":52},"https://docshare.wps.com/document/space-sound-and-acousmatic-music-the-heart-of-the-research/156017/",4,{"url":51,"name":13,"@type":54,"author":55,"headline":13,"publisher":57,"fileFormat":60,"inLanguage":23,"description":14,"dateModified":61,"datePublished":61,"encodingFormat":60,"isAccessibleForFree":62,"interactionStatistic":63},"DigitalDocument",{"name":9,"@type":56},"Person",{"url":41,"name":58,"@type":59},"DocShare","Organization","application/pdf","2026-08-28",true,{"@type":64,"interactionType":65,"userInteractionCount":4},"InteractionCounter",{"@type":66},"ViewAction",{"@type":68,"mainEntity":69},"FAQPage",[70,76,80],{"name":71,"@type":72,"acceptedAnswer":73},"What does “spatial projection” mean in acousmatic listening?","Question",{"text":74,"@type":75},"It refers to projecting sound into space so that the listener experiences the space of sound as part of musical expression.","Answer",{"name":77,"@type":72,"acceptedAnswer":78},"How are the four main spatial categories defined?",{"text":79,"@type":75},"They include ambiophonic/surround space, sound-source space, geometry space, and space illusion in traditional stereo.",{"name":81,"@type":72,"acceptedAnswer":82},"Why is source space compared to pointillism?",{"text":83,"@type":75},"Because it pinpoints the sound source with localization emphasized, using short, delineated attack transients so the listener can track individual speakers.","https://schema.org",{"og:url":51,"og:type":86,"og:title":13,"og:site_name":58,"og:description":14},"article",{"robots":88,"canonical":51},"index,follow",{"doc_id":7,"site_id":24},{"code":4,"msg":5,"data":91},[92,96,99,103,108,113,118,123,128,131,135],{"id":20,"doc_module":4,"doc_module_name":46,"category_name":93,"show_sort_weight":94,"slug":95},"Story & Novel",90,"story-novel",{"id":11,"doc_module":4,"doc_module_name":46,"category_name":12,"show_sort_weight":97,"slug":98},80,"literature",{"id":52,"doc_module":4,"doc_module_name":46,"category_name":100,"show_sort_weight":101,"slug":102},"Exam",70,"exam",{"id":104,"doc_module":4,"doc_module_name":46,"category_name":105,"show_sort_weight":106,"slug":107},5,"Comic",60,"comic",{"id":109,"doc_module":4,"doc_module_name":46,"category_name":110,"show_sort_weight":111,"slug":112},6,"Technology",50,"technology",{"id":114,"doc_module":4,"doc_module_name":46,"category_name":115,"show_sort_weight":116,"slug":117},7,"Healthcare",40,"healthcare",{"id":119,"doc_module":4,"doc_module_name":46,"category_name":120,"show_sort_weight":121,"slug":122},8,"Research & Report",30,"research-report",{"id":124,"doc_module":4,"doc_module_name":46,"category_name":125,"show_sort_weight":126,"slug":127},9,"Religion & Spirituality",20,"religion-spirituality",{"id":126,"doc_module":4,"doc_module_name":46,"category_name":129,"show_sort_weight":126,"slug":130},"World Cup","world-cup",{"id":132,"doc_module":4,"doc_module_name":46,"category_name":133,"show_sort_weight":132,"slug":134},10,"Lifestyle","lifestyle",{"id":136,"doc_module":4,"doc_module_name":46,"category_name":137,"show_sort_weight":104,"slug":138},19,"General","general"]
