In this talk, we touch upon the chaotic and fractal aspects of the Universe.

This paper discusses a hybrid audio synthesis method employing both additive synthesis and DPCM audio playback, and the implementation of a miniature synthesizer system that accepts MIDI as an input format. Additive synthesis is performed in the frequency domain using a weighted overlap-add filterbank, providing efficiency gains compared to previously known methods. The synthesizer system is im...

We usually think of an audio application as a self-contained executable that will compute audio, allow user interface control, and render sound in a single process, on a unique machine. With the appearance of fast network and sophisticated, light and wireless control devices (such as tablets, smartphones...) the three different parts (that are audio computation, interface control and sound rend...

Recently, the requirements for the real-sense media representation are increasing rapidly. Until now, most people mainly used the method SMSD on one device, but we need more than one device to play multiple audio/videos and multiple sensory effects of the real-sense media. Therefore, multi-track media synchronization and effect device synchronization algorithms are very important part of the re...

In the search for low-cost, highly available devices for real time audio processing for scientific or artistic purposes, the Arduino platform comes in as a handy alternative for a chordless, versatile audio processor. Despite the fact that Arduinos are generally used for controlling and interfacing with other devices, its built-in ADC/DAC allows for capturing and emitting raw audio signals with...

Current mobile technology works well to connect individuals together at any time or place. However, general focus on one-to-one conversations has overlooked the potential of always-on group and community links. We hypothesize that asynchronous persistent audio is a superior medium to support scalable always-on group communication for mobile devices. To evaluate this claim, one must first have a...

Future generations of mobile communication devices will serve more and more as multimedia platforms capable of reproducing high quality audio. In order to achieve a 3-D sound perception the reproduction quality of audio via headphones can be significantly increased by applying binaural technology. To be independent of individual head-related transfer functions (HRTFs) and to guarantee a good pe...

Ubiquitous environment's research has evolved considerably over the last years. The wide range of mobile devices, their high diversity and mobility have raised a variety of challenges being resource management a predominant, and therefore attracting special attention in the research community. The Composable-Adaptive Resource Management (CARM) middleware library provides a exible infrastructure...

Despite widespread interest, electronic commerce for audio currently still presents a major challenge with regard to aspects such as security, transaction handling, interoperability of devices and services and end user experience. While many component technologies are already available addressing certain aspects of this scenario, a seamless integration of these functionalities into one unified ...
