Upcoming Events

Pat Scandalis - Physically Modeled Musical Instruments on Mobile Devices

Date: 
Thu, 05/21/2015 - 5:15pm - 6:30pm
Location: 
Classroom
Event Type: 
Guest Colloquium
Handheld mobile computing devices are now ubiquitous. These devices are powerful, connected and equipped with a variety of sensors. Their pervasiveness has created an opportunity to realize parametrically controlled, physically modeled, virtual musical instruments. moForte inc was founded to develop a line of sonic and musical applications for handheld devices. We developed the "moForte Guitar Stack" which models the guitar family of instruments. This stack has been used to used to develop applications for mobile devices.

We give an overview of the history of physical modeling with many sound examples, and then brief overview of the current state of modeling on mobile devices using a few apps based on the moForte Guitar Stack.

Alex Brandmeyer on High-frequency Neural oscillations for Auditory Perception

Date: 
Fri, 05/22/2015 - 11:30am - 1:00pm
Location: 
CCRMA Seminar Room (Top Floor of the Knoll)
Event Type: 
Hearing Seminar
Our transparent everyday experience of sound belies the complex perceptual processes which transform acoustic energy in the environment into rich representations of sound-emitting objects. Since the publication of Bregman’s seminal work on ‘Auditory Scene Analysis’, much progress has been made in understanding the neural mechanisms that support the formation of auditory streams and object representations. This talk will focus on the functional role of neural oscillations in audition, and the interplay between top-down (i.e. attentional and executive processes) and bottom-up (sensory) processes during the formation of perceptual representations.

François-Xavier Féron - Retracing the impact of musical acoustics on Gérard Grisey’s creative process in the 1970s: from spectral models to spectrogram transcriptions

Date: 
Wed, 05/27/2015 - 5:15pm - 6:30pm
Location: 
Classroom
Event Type: 
Guest Colloquium

From its emergence in France at the beginning of the 1970s, spectral music has represented one of the main musical streams. Composed by Gérard Grisey over a decade, from 1974 to 1985, the six-piece cycle Les espaces acoustiques illustrates a new approach towards composition, one that deals with acoustic properties and is constantly preoccupied with the modalities of auditory perception. This cycle is based on a harmonic spectrum with fundamental frequency 41,2 Hz (E1). Grisey also collaborated with the acoustician Michèle Castellengo, with whom he analysed instrumental sounds spectrograms in order to compose "synthetic spectra" and "spectral polyphony".

Guest Lecture: Julia Litman-Cleper. Sound Mappings: Inhabiting virtual geometry through sound.

Date: 
Thu, 04/23/2015 - 5:15pm - 6:00pm
Location: 
CCRMA Stage
Event Type: 
Guest Lecture
The experience of hearing one’s own voice “from the outside,” usually through an electronic device, is often at first described as “weird” or “strange” and jarring. This talk will discuss the role of internal sound and self-referent external sound in relation to proprioceptive processes, or the sense of oneself in physical space.  Sound compositions may have the capacity to change proprioceptive mappings through inducing otherwise unknowable quasi-spatial experience. We will speculate on possible reasons why it may be so. How is it that certain kinds of sound patterns can cause a deviation from what is otherwise normalized expectations of events in time.

Recent progress in efficient physics-based synthesis of string instrument sound

Date: 
Thu, 04/23/2015 - 5:15pm - 7:00pm
Location: 
CCRMA Classroom [Knoll 217]
Event Type: 
DSP Seminar

ABSTRACT

Applications combining digital waveguides, modal synthesis, and finite-difference time-domain modeling will be presented in the context of efficient simulation of string instruments.

The first part of this talk will introduce a technique for modeling bridge admittances and body radiativity profiles from frequency response measurements on guitars and bowed string instruments. The formulation, relying on modal analysis, is then used to construct reflectance and radiativity models enabling efficient simulation of string plucks via digital waveguides.

Palette of sound: Triple CCRMAlite’s excursion through time

The Triple CCRMAlite performance this past Sunday at Bing Concert Hall was a celebration of three important dates for the Center for Computer Research in Music and Acoustics (CCRMA): the 40th anniversary of CCRMA, the 50th anniversary of the first computer program for music on campus, and the 80th birthday of CCRMA founder John Chowning Ph.D. ’66. The program featured a science fair of student research in the lobby, as well as a concert showcasing works from Chowning, French composer Jean-Claude Risset, and former CCRMA Research Associate Bill Schottstaedt.
