MUS423 Research Seminars
The CCRMA Music 423 Research Seminar brings graduate students and supervising faculty together for planning and discussion of original research. Students and faculty meet either in small groups or individually, as appropriate for the research topics and interests of the participants. Research carried out is typically presented at the weekly CCRMA Colloquium (if it is of general interest to the CCRMA community) or at a Special DSP Seminar scheduled for that purpose. In either case, announcements appear on the CCRMA Home Page as Upcoming Events.

Abstract: Jianhua Yuan will present a series of techniques, based upon the energy based acoustic features, to locate a sound source given measurements of the sound field. For wireless ad hoc sensor network applications, energy based acoustic features is an appropriate choice since the acoustic power emitted by targets, such as moving vehicles usually varies slowly with respect to time. In this approach, mathematical models and new numerical methods may be used to yield higher accuracy in terms of source location estimates compared to the earlier method.

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.FREEOpen to the PublicAn interactive interface for predominant pitch extraction, and its applications in singing evaluation, source separation and cover-version generation.

Date:Mon, 03/03/2014 - 5:30pm - 7:00pmLocation:CCRMA ClassroomEvent Type:DSP SeminarCan a digital system provide satisfactory emulations of classic analog musical instruments and effects? Polarized reactions to the impending release (this month!) of Roland's TR-8 Rhythm Performer (a digitally modeled TR-808/909) have reignited this old debate. I've focused my research on creating physically-informed, circuit-bendable, digital models of analog drum machines. At this DSP Seminar, I'll present my methodological framework and analysis/models of one of the 808's most famous sound generators: the bass drum. My digital model, implemented in Cycling 74's Gen~, retain the salient features of the original analog drum machine and allow for accurate emulation of circuit-bending and common 808 mods. This work takes an engineering approach to hacking and circuit bending, clears up misconceptions about the 808's circuitry, and plugs a conspicuous drum-machine-shaped gap in virtual analog research.

Date:Tue, 11/12/2013 - 5:30pm - 6:45pmLocation:CCRMA ClassroomEvent Type:DSP SeminarAbstract: In the second talk of a two-part series, we will further discuss ISSE--an interactive source separation editor. As described earlier, ISSE is a new, open-source, freely available, cross-platform audio editing software tool which enables a user to perform single-channel source separation by painting on time-frequency visualizations of sound. It is useful for a variety of music- and audio-related tasks such as music remixing, audio denoising, and audio-based forensics.
