href="/w/index.php?title=Aureal_Semiconductor&action=edit&redlink=1" class="new" title="Aureal Semiconductor (de pagina bestaat niet)">Aureal Semiconductor</a> in de tweede helft van de jaren 1990. Het systeem werd oorspronkelijk geïntegreerd in Aureals <a href="/w/index.php?title=Aureal_Vortex&action=edit&redlink=1" class="new" title="Aureal Vortex (de pagina bestaat niet)">Vortex</a>-<a href="/wiki/Geluidskaart" title="Geluidskaart">geluidskaart</a>. A3D creëert driedimensionale effecten waardoor het menselijk oor het geluid aan een bepaalde richting kan toewijzen. Hiervoor maakt de technologie gebruik van <a href="/w/index.php?title=Head-related_transfer_function&action=edit&redlink=1" class="new" title="Head-related transfer function (de pagina bestaat niet)">HRTF</a>. A3D is vooral handig bij dynamische of interactieve toepassingen zoals <a href="/w/index.php?title=Simulatiespellen&action=edit&redlink=1" class="new" title="Simulatiespellen (de pagina bestaat niet)">simulatiespellen</a> en actiespellen zodat de speler weet welke richting hij wel/niet uit kan aan bijvoorbeeld de geweerschoten van de vijand. </p><p>Men kan het effect van A3D min of meer vergelijken met een <a href="/wiki/Vliegen_(dieren)" title="Vliegen (dieren)">vlieg</a> die rond een persoon zijn hoofd vliegt. Zelfs als die persoon zijn ogen sluit, weet hij aan het gebrom waar die vlieg zich ongeveer bevindt. </p><p>Het grote voordeel van A3D is dat het systeem werkt met een gewone <a href="/wiki/Hoofdtelefoon" title="Hoofdtelefoon">hoofdtelefoon</a> of twee gewone externe <a href="/wiki/Luidspreker" title="Luidspreker">luidsprekers</a>. Op een muziekkaart met de A3D-functie na heeft men dus geen speciale componenten nodig. Dit is in contrast met <a href="/wiki/Surround_sound" class="mw-redirect" title="Surround sound">surround sound</a> waar het aangeraden is om met vier of meerdere luidsprekers te werken. </p><p>Het bedrijf <a href="/wiki/Creative_Technology" title="Creative Technology">Creative Labs</a> had een gelijkaardige techniek: <a href="/w/index.php?title=Environmental_Audio_Extensions&action=edit&redlink=1" class="new" title="Environmental Audio Extensions (de pagina bestaat niet)">EAX</a>. Creative Labs spande in maart 1998 een <a href="/wiki/Rechtszaak" title="Rechtszaak">rechtszaak</a> aan omdat zij van mening waren dat Aureal Semiconductor een van hun <a href="/wiki/Octrooi" title="Octrooi">patenten</a> onrechtmatig gebruikte.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Aureal won de rechtszaak in december 1999, maar had er dusdanig veel schade door opgelopen dat het bedrijf <a href="/wiki/Faillissement" title="Faillissement">failliet</a> ging. In september 2000 nam Creative het bedrijf Aureal over op voorwaarde dat alle claims over A3D zouden vervallen. Hoewel Creative Labs daarna besloot om A3D niet verder te ondersteunen, werd het wel gedeeltelijk verder ingebouwd in de nieuwere versie van EAX. </p> <div class="toccolours appendix" role="presentation" style="font-size:90%; margin:1em 0 -0.5em; clear:both;"> <div><span style="font-weight:bold">Bronnen, noten en/of referenties</span></div> <div class="reflist" style="list-style-type: decimal;"><div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text">Onrechtmatig gebruik van octrooien, aureal.com (pagina niet meer beschikibaar)</span> </li> </ol></div></div> </div>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1&useformat=desktop" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Overgenomen van "<a dir="ltr" href="https://nl.wikipedia.org/w/index.php?title=A3D&oldid=49222128">https://nl.wikipedia.org/w/index.php?title=A3D&oldid=49222128</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Categorie:Alles" title="Categorie:Alles">Categorieën</a>: <ul><li><a href="/wiki/Categorie:Geluidsapparatuur" title="Categorie:Geluidsapparatuur">Geluidsapparatuur</a></li><li><a href="/wiki/Categorie:Geluidschip" title="Categorie:Geluidschip">Geluidschip</a></li><li><a href="/wiki/Categorie:Geluidskaart" title="Categorie:Geluidskaart">Geluidskaart</a></li><li><a href="/wiki/Categorie:Muzieksoftware" title="Categorie:Muzieksoftware">Muzieksoftware</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> Deze pagina is voor het laatst bewerkt op 3 jun 2017 om 14:09.</li> <li id="footer-info-copyright">De tekst is beschikbaar onder de licentie <a rel="nofollow" class="external text" href="//creativecommons.org/licenses/by-sa/4.0/deed.nl">Creative Commons Naamsvermelding/Gelijk delen</a>, er kunnen aanvullende voorwaarden van toepassing zijn.
