Users@Planet CCRMA
Users@Planet CCRMA (The Linux Survival Guide) Juan Reyes [email protected] Abstract This guide takes the approach of a traveler’s survival companion and its sole purpose is to illustrate, show and inform new CCRMA users and visitors about computer resources and the Linux environment and applications which might be helpful for doing scientific research and compositional work at CCRMA. It also briefly describes the meaning of Open Source as a part of the laboratory and community philosophy here at CCRMA. Following is a brief history of hardware at CCRMA and descriptions of Linux as an operating system, the Unix environment, useful shell commands and many X windows, Gnome and KDE applications. In the applications section there will be useful descriptions of programs and information provided by developers’ documentation but do not discard some of the tricks and options as to our knowledge we present to the reader in some of these sections. If additional information is required in the case of a particular command, program or application, the reader is encouraged to look for more in-depth information on the Unix manual pages, on the web or in the links to home pages which are also provided here. Furthermore, there is some effort in several sections, to present solutions to common problems or challenges the system presents to the common user, beware of them.

Latency and Amount of Correctly Aligned Audio - LAN (No Redundancy) APPENDIX Z
EVALUATING NMP QUALITY OF SERVICE Experiment with JackTrip regarding Latency versus Packet Jitter/Dropouts with High Quality Audio via LAN and WAN UTVÄRDERING AV QUALITY OF SERVICE VID NMP Experiment med JackTrip angående Latens kontra Jitter/Tapp av Paket med Högkvalitetsljud via LAN och WAN Bachelor Degree Project in Information Technology G2E 22,5 hp Spring term 2018 Daniel Müntzing, [email protected] Supervisor: Dennis Modig Examiner: Jianguo Ding 1 Abstract This study has developed a method to create an, to a big extent, automated testing system for NMP (Networked Music Performance) communication over LAN and WAN to be able to benchmark the UDP streaming engine JackTrip using a client-server model. The method is not locked into using JackTrip only, it could be used to do experiments with other engines too. The study tried to answer the question if latency correlates to amount of correctly aligned audio, and to what extent the audio is correctly aligned in respect to tolerated latency (based on earlier research) when at least two musicians remote- conducting musical pieces together. There were 13 different buffer settings tested, which used no redundancy and redundancy of 2, and which were sent through 4 different LAN/WAN-scenarios. A big dataset was produced, with about 82 minutes’ worth of audio per test. To post-process the data a phase cancelling method was used to measure correctly aligned audio, while the latency was measured by counting the number of samples from the start of each audio file to the first sample that were not null or not under a certain threshold. -
A Survey of Some Virtual Reality Tools and Resources
2 A Survey of Some Virtual Reality Tools and Resources Moses Okechukwu Onyesolu, Ignatius Ezeani and Obikwelu Raphael Okonkwo Nnamdi Azikiwe University, Awka, Anambra State Nigeria 1. Introduction Virtual Reality (VR) technology enables users to interact with three-dimensional data, providing a potentially powerful interface to both static and dynamic information (Ausburn & Ausburn, 2003; Ausburn & Ausburn, 2004; Baieier, 1993; Onyesolu, 2011; Onyesolu & Eze, 2011). VR has existed in various forms since its inception. It has been known by names such as synthetic environment, cyberspace, artificial reality, simulator technology and so on and so forth before VR was eventually adopted (Onyesolu, 2006; Onyesolu & Eze, 2011). Though VR has existed from the late 1960s, its latest manifestation, desktop screen-based semi- immersive type which made its first appearance in entertainment industry, has made it come within the realm of possibility for general creation and use. As a result of proliferation of desktop VR, the technology has continued to develop applications that are less than fully immersive. These non-immersive VR applications are far less expensive and technically daunting and have made inroads into industry training and development. There have been a lot of advances in VR and VR is being applied in all areas of human endeavor (Onyesolu, 2009a; Onyesolu, 2009b; Onyesolu & Eze, 2011; Onyesolu, 2006). Many VR applications have been developed for manufacturing, training in a variety of areas (military, medical, equipment operation, etc.), education, simulation, design evaluation, architectural walk-through, ergonomic studies, simulation of assembly sequences and maintenance tasks, assistance for the handicapped, study and treatment of phobias, entertainment, rapid prototyping and much more (Onyesolu & Akpado, 2009).
