Sound Synthesis by Computer: Models for the Interaction of the Player with Strings, a lecture by professor Gianpaolo Evangelista. Thursday, October 19th, 2023 at 5pm. Room 387-1015.

Sound Synthesis by Computer: Models for the Interaction of the Player with Strings

Abstract

Models for the interaction of the player with the instrument are fundamental to the accurate synthesis of sound based on physically inspired models. Depending on the musical instrument, the palette of possible interactions is generally very broad and includes the coupling of body parts, mechanical objects and/or devices with various components of the instrument. In this talk we focus on the interaction of the player with strings, whose simulation requires accurate models of the fingers, dynamic models of the bow, of the plectrum and of the friction of objects such as bottle necks. We also consider collisions and imperfect pressure on the fingerboard as important side effects and playing styles. Our models do not depend on the specific numerical implementation but are simply illustrated in the digital waveguide scheme.

Gianpaolo Evangelista is professor of Music Informatics at the University of Music and Performing Arts Vienna, Austria. Previously he was professor of Sound Technology at Linköping University, Sweden, researcher and assistant professor at the University “Federico II” of Naples, Italy and adjunct professor at the Polytechnic of Lausanne (EPFL), Switzerland. He received the Laurea in Physics from the University “Federico II” of Naples and the Master and PhD in Electrical and Computing Engineering from the University of California Irvine. He has collaborated with several musicians among including Iannis Xenakis (Paris) and Curtis Roads. His interests are in all applications of Signal Processing, Physics and Mathematics to Sound and Music, particularly for the analysis, synthesis, special effects and the separation of sound sources.

Leading AI researcher Mustafa Suleyman will be the guest lecturer for THEMAS 80TH on October 5th, 2023 at 2pm.

Suleyman will also give a lecture for the UCSB Arts and Lectures series in Campbell Hall on October 5th, 2023 at 7:30pm.

MAT PhD student You-Jin Kim is presenting his research paper titled "Dynamic Theater: Location-Based Immersive Dance Theater, Investigating User Guidance and Experience" at the 29th ACM Symposium on Virtual Reality Software and Technology (VRST) from October 9 to 11, 2023 in Christchurch, New Zealand. In addition he is also presenting his research paper titled "Reality Distortion Room: A Study of User Locomotion Responses to Spatial Augmented Reality Effects" at the 22nd IEEE International Symposium on Mixed and Augmented Reality (ISMAR) from October 16 to 20, 2023 in Sydney, Australia.

Dynamic Theater: Location-Based Immersive Dance Theater, Investigating User Guidance and Experience

Abstract

Dynamic Theater explores the use of augmented reality (AR) in immersive theater as a platform for digital dance performances. The project presents a locomotion-based experience that allows for full spatial exploration. A large indoor AR theater space was designed to allow users to freely explore the augmented environment. The curated wide-area experience employs various guidance mechanisms to direct users to the main content zones. Results from our 20-person user study show how users experience the performance piece while using a guidance system. The importance of stage layout, guidance system, and dancer placement in immersive theater experiences are highlighted as they cater to user preferences while enhancing the overall reception of digital content in wide-area AR. Observations after working with dancers and choreographers, as well as their experience and feedback are also discussed. Co-authors are Joshua Lu, and Tobias Höllerer.

Reality Distortion Room: A Study of User Locomotion Responses to Spatial Augmented Reality Effects

Abstract

Reality Distortion Room (RDR) is a proof-of-concept augmented reality system using projection mapping and unencumbered interaction with the Microsoft RoomAlive system to study a user’s locomotive response to visual effects that seemingly transform the physical room the user is in. This study presents five effects that augment the appearance of a physical room to subtly encourage user motion. Our experiment demonstrates users’ reactions to the different distortion and augmentation effects in a standard living room, with the distortion effects projected as wall grids, furniture holograms, and small particles in the air. The augmented living room can give the impression of becoming elongated, wrapped, shifted, elevated, and enlarged. The study results support the implementation of AR experiences in limited physical spaces by providing an initial understanding of how users can be subtly encouraged to move throughout a room. Co-authors are Andrew D. Wilson, Jennifer Jacobs, and Tobias Höllerer.

Professor JoAnn Kuchera-Morin gave a talk titled "The Multi-Modality of Complex Systems - Special-Temporal Exploration", at ACM SIGGRAPH DAC SPARKS - The Art of Scientific Visualization: Perceiving the Imperceptible, on April 28, 2023.

Abstract

Complex systems in nature unfold over many spatial and temporal dimensions. Those systems easy for us to perceive as the world around us are limited by what we can see, hear, and interact with. But what about complex systems that we cannot perceive, those systems that exist at the atomic or sub-atomic? Can we bring these systems to human scale and view this data just as we do in viewing real-world phenomena? As a composer working with sound on many spatial temporal dimensions, shape and form comes to life through sound transformation. What seems to be visually imperceptible becomes real and visually perceptible in the composer’s mind. As media artists we can now take these transformational structures from the auditory to the visual and interactive domain through frequency transformation. Can we apply these transformations to complex imperceptible scientific models to see, hear, and interact with these systems bringing them to human scale?

About the SPARKS session:

Our understanding of the world is limited by the capacity of our senses to ingest information and also by our brain’s ability to interpret it. Through the use of technology, we know that the universe we live in is far more complex and rich with information than what can be perceived by humanity. From microscopic to cosmic, information that transcends our lived experiences is difficult to comprehend. Our ability to augment our senses with technology has resulted in an accumulation of vast amounts of data, often in a form that needs to be translated to be understood. This SPARKS session explores the conceptual and creative aspects of scientific visualization.

DAC SPARKS - The Art of Scientific Visualization: Perceiving the Imperceptible - April 28, 2023.

Xenos, a new virtual instrument plug-in that implements and extends the Dynamic Stochastic Synthesis (DSS) algorithm, has been released. Developed by MAT alumni Raphael Radna as part of his Masters degree, Xenos implements DSS with modifications and extensions that enhance its suitability for general composition.

Released in March 2023, Xenos is a virtual instrument plug-in that implements and extends the Dynamic Stochastic Synthesis (DSS) algorithm invented by Iannis Xenakis and notably employed in the 1991 composition GENDY3. DSS produces a wave of variable periodicity through regular stochastic variation of its wave cycle, resulting in emergent pitch and timbral features. While high-level parametric control of the algorithm enables a variety of musical behaviors, composing with DSS is difficult because its parameters lack basis in perceptual qualities.

Xenos thus implements DSS with modifications and extensions that enhance its suitability for general composition. Written in C++ using the JUCE framework, Xenos offers DSS in a convenient, efficient, and widely compatible polyphonic synthesizer that facilitates composition and performance through host-software features, including MIDI input and parameter automation. Xenos also introduces a pitch-quantization feature that tunes each period of the wave to the nearest frequency in an arbitrary scale. Custom scales can be loaded via the Scala tuning standard, enabling both xenharmonic composition at the mesostructural level and investigation of the timbral effects of microtonal pitch sets on the microsound timescale.

A good review of Xenos can be found at Music Radar: www.musicradar.com/news/fantastic-free-synths-xenos.

"MAT is a rare graduate program in that it operates more like an creative ecosystem -- your work as a researcher is significant and connects to others. People care a lot about what you are doing, and invest thought into your own thinking. Throughout my eight years of study, from 2007 to 2015, and as a postdoctoral student afterwards, this supportive environment provided the technological, financial, and intellectual resources necessary for me to take risks in my work. As a result, I was able to dive deep into subjects I thought were off limits to my cognitive function, and achieve the great satisfaction of learning how to learn better. It is a testament to the culture fostered there that an experimental filmmaker such as myself entering the program with very basic programming skills can now make regular contributions to mathematics journals, work as a real-time computer graphics programmer in the DTLA arts district, be asked to consult on science fiction television dramas, and innovate novel geometrical algorithms of use in architecture. I think the MAT program at UCSB is a hidden gem -- you enter it with one direction in mind, and come out brilliantly refracted into a spectrum of possibilities."
