Ensimmäisessä kappaleessa esitetään opinnäytetyön tavoitteet ja viimeisessä kappaleessa esitetään opinnäytetyön johtopäätökset, jossa myös mainitaan eräitä aiheita, jotka jätettiin pois opinnäytetyön aihealueen rajoittamisen vuoksi. Abstract Author: Abbott David Title of the Publication: Using FMOD Studio with Unity Degree Title: Bachelor’s Degree in Business Information Technology Keywords: FMOD, audio engine, middleware, Unity, sound design This thesis covers the use of FMOD Studio in conjunction with the Unity game engine to create the basic audio systems most needed in a typical video game, as well as some of the more ad- vanced systems that might be needed such as a footstep audio system. This thesis was not commissioned by an outside party. The sources of the thesis consist of the FMOD user guide, as well as various other websites related to the topic. Using the source material and my experience working with FMOD Studio on multiple project, the most important features of FMOD Studio and the FMOD Studio API have been covered in this thesis. The theoretical section of this thesis contains a brief overview of FMOD, what its features are, the licensing terms under which it can be used and the support for different platforms, file formats and game engines it provides. The empirical section contains in-depth explanations and exam- ples of most of the features of FMOD Studio and how they can be used in conjunction with the Unity game engine. The first chapter contains the objectives and goals of this thesis while the last chapter contains the conclusions of the thesis including certain topics that were left out due to limiting the scope of the thesis.

The approved original version of this diploma or master thesis is available at the main library of the Vienna University of Technology (http://www.ub.tuwien.ac.at/englweb/). MASTERARBEIT Foundations for Music-Based Games Ausgeführt am Institut für Gestaltungs- und Wirkungsforschung der Technischen Universität Wien unter der Anleitung von Ao.Univ.Prof. Dipl.-Ing. Dr.techn. Peter Purgathofer und Univ.Ass. Dipl.-Ing. Dr.techn. Martin Pichlmair durch Marc-Oliver Marschner Arndtstrasse 60/5a, A-1120 WIEN 01.02.2008 Abstract The goal of this document is to establish a foundation for the creation of music-based computer and video games. The first part is intended to give an overview of sound in video and computer games. It starts with a summary of the history of game sound, beginning with the arguably first documented game, Tennis for Two, and leading up to current developments in the field. Next I present a short introduction to audio, including descriptions of the basic properties of sound waves, as well as of the special characteristics of digital audio. I continue with a presentation of the possibilities of storing digital audio and a summary of the methods used to play back sound with an emphasis on the recreation of realistic environments and the positioning of sound sources in three dimensional space. The chapter is concluded with an overview of possible categorizations of game audio including a method to differentiate between music-based games.

  • The Impact of Multichannel Game Audio on the Quality of Player Experience and In-Game Performance
    The Impact of Multichannel Game Audio on the Quality of Player Experience and In-game Performance Joseph David Rees-Jones PhD UNIVERSITY OF YORK Electronic Engineering July 2018 2 Abstract Multichannel audio is a term used in reference to a collection of techniques designed to present sound to a listener from all directions. This can be done either over a collection of loudspeakers surrounding the listener, or over a pair of headphones by virtualising sound sources at specific positions. The most popular commercial example is surround-sound, a technique whereby sounds that make up an auditory scene are divided among a defined group of audio channels and played back over an array of loudspeakers. Interactive video games are well suited to this kind of audio presentation, due to the way in which in-game sounds react dynamically to player actions. Employing multichannel game audio gives the potential of immersive and enveloping soundscapes whilst also adding possible tactical advantages. However, it is unclear as to whether these factors actually impact a player’s overall experience. There is a general consensus in the wider gaming community that surround-sound audio is beneficial for gameplay but there is very little academic work to back this up. It is therefore important to investigate empirically how players react to multichannel game audio, and hence the main motivation for this thesis. The aim was to find if a surround-sound system can outperform other systems with fewer audio channels (like mono and stereo). This was done by performing listening tests that assessed the perceived spatial sound quality and preferences towards some commonly used multichannel systems for game audio playback over both loudspeakers and headphones.

Received: 6 April 2020; Accepted: 23 April 2020; Published: 25 April 2020 Abstract: Individuals with autism spectrum disorder (ASD) are characterised as having impairments in social-emotional interaction and communication, alongside displaying repetitive behaviours and interests. Additionally, they can frequently experience difficulties in processing sensory information with particular prevalence in the auditory domain. Often triggered by everyday environmental sounds, auditory hypersensitivity can provoke self-regulatory fear responses such as crying and isolation from sounds. This paper presents SoundFields, an interactive virtual reality game designed to address this area by integrating exposure based therapy techniques into game mechanics and delivering target auditory stimuli to the player rendered via binaural based spatial audio. A pilot study was conducted with six participants diagnosed with ASD who displayed hypersensitivity to specific sounds to evaluate the use of SoundFields as a tool to reduce levels of anxiety associated with identified problematic sounds. During the course of the investigation participants played the game weekly over four weeks and all participants actively engaged with the virtual reality (VR) environment and enjoyed playing the game.
