Dynamische Binauralsynthese FüR Mobile Anwendungen

Abstract

The recent huge increase in processing power of mobile devices allows them to be used for applications previously limited to the class of personal computers. Due to the increased portability and the extended means of interaction, mobile devices open up new fields of applications, which are not fully explored yet. This thesis examines the feasibility of implementing dynamic binaural synthesis on the Android platform - which at the moment is the most widespread platform for mobile devices. The implementations of a low-cost head-tracking system and an Android application are derived and explained. On the basis of the implementations, platform-specific obstacles and particularities are investigated and evaluated. It is shown that dynamic binaural synthesis on Android is possible with good results, but that there are several machanisms that prevent the software to make full use of the present hardware and thus degrade performance to a level below hardware capabilities. ----- Die enorm gestiegene Rechenleistung mobiler Geräte ermöglicht es mehr und mehr, diese auch für anspruchsvolle Anwendungen einzusetzen, welche bis vor kurzem noch der Klasse der Personal Computer vorbehalten waren. In Verbindung mit ihrer erhöhten Portabilität und ihren erweiterten Interaktions- möglichkeiten ergeben sich neue und bisher nicht vollkommen erschlossene Anwendungsgebiete. Die vorliegende Arbeit untersucht die Umsetzbarkeit der dynamischen Binauralsynthese auf der Android-Plattform - der zu diesem Zeitpunkt verbreitetsten Plattform für mobile Geräte. Dazu werden die Implementationen eines mobilen Low-Cost Head-Tracking-Systems und einer Android-Anwendung hergeleitet und vorgestellt. Anhand der Implementationen werden plattformspezifische Hürden und Besonderheiten erforscht und ausgewertet. Es wird gezeigt, dass die dynamische Binauralsynthese auf Android mit guten Ergebnissen möglich ist, es jedoch bestimmte Mechanismen gibt, welche das Erreichen von sehr guten und mit der Hardware prinzipiell erreichbaren Ergebnissen verhindern.
