Colloquium Series
The CCRMA Colloquium is a weekly gathering of CCRMA students, faculty, staff, and guests. It is an opportunity for members of the CCRMA community and invited speakers to share the work that they are doing in the field of Computer Music. The colloquium typically happens every Wednesday during the school year from 5:30 - 7:00pm and meets in the CCRMA Classroom, Knoll 217 unless otherwise noted.
The schedule for this year's CCRMA Colloquium can be found here: ccrma.stanford.edu/wiki/Colloquium
Colloquia and concerts are announced via a mailing list.
Recent Colloquia

SICA artist in residency 2009 and the performance of his "Finale" 2012 by TheStanford Symphony Orchestra.
Open to the PublicRoy Pertchik: The Tri-Chromatic Keyboard and the Symmetry of Music
Date:Wed, 05/14/2014 - 5:15pm - 6:30pmLocation:CCRMA StageEvent Type:Colloquium
A highly symmetrical musical keyboard and a small system of just a few new musical scales provide a powerful way to access a wide variety of musical harmony. The keyboard is isomorphic, a "6+6" (all half steps), and is marked in 3 groups of diminished 3rd's (the 3 diminished chords.) A very few scales based on the diminished chords are shown to produce a wide variety of harmony in a controlled way. A few identities provide "tinker-toy" links between different scales and different keys, and allow for the construction of many familiar chord progressions as well as advanced harmonic substitutions. The whole system includes binary selections at different levels, offering good handles for interface design.
Open to the PublicEvelina Rajca : Recent Works
Date:Wed, 05/07/2014 - 5:15pm - 7:00pmLocation:CCRMA Classroom, The Knoll 2nd floor, Rm 217Event Type:Colloquium
Evelina Rajca's practice is based in between intuitive embodied knowledge and systems that construct processes of documenting these experiences, translating them into interventions, objects, maps and scores. She uses old and new technologies as working materials in an ever-changing process. Her performative explorations in the form of collaborations, sculptures and interventions in public space stimulate the question of who inhabits that space under constant transformation. In her colloquium she will present a selection of her practice based artistic research.

FREEOpen to the PublicFrançois Germain: Towards practical source-independent algorithms using nonnegative matrix factorization
Date:Wed, 04/23/2014 - 5:15pm - 7:00pmLocation:CCRMA Classroom, The Knoll 2nd floor, Rm 217Event Type:ColloquiumLimitations of nonnegative matrix factorization (NMF) were recently circumvented through the development of "universal source models" which exploit the similarities inside a given class of sources in order to eliminate the need for user-provided training data. The resulting system is unsupervised from the user perspective which strongly improves its range of practical use. This method was applied to applications such as offline speech enhancement, voice activity detection and singing voice separation.
Full abstract:Open to the PublicDana Massie - Sample rate conversion with MaxSRC
Date:Wed, 04/16/2014 - 5:15pm - 7:00pmLocation:CCRMA, 2nd floor, Rm 217Event Type:Colloquium
A digital method for sample rate conversion using recursive IIR “phasor” filters, denoted MaxSRC, named in honor of Max Mathews whose work popularized the term “phasor filter". High quality sample rate conversion is useful for many applications in computer audio and music, including sound synthesis and sampled waveform playback. The most common methods used historically for sample rate conversion use FIR filters. MaxSRC uses time-varying IIR filters.
Open to the PublicJosé Echeveste: Antescofo, a dynamic language for real-time musician-computer interaction
Date:Mon, 04/14/2014 - 5:15pm - 6:45pmLocation:CCRMA Classroom, The Knoll 2nd floor, Rm 217Event Type:Colloquium
This talk focuses on programing of time and interaction in Antescofo, a real-time system for performance coordination between musicians and computer processes during live music performance. To this end, Antescofo relies on artificial machine listening and a domain specific real-time programing language. It extends each paradigm through strong coupling of the two and strong emphasis on temporal semantics and behavior of the system.The challenge in bringing human actions in the loop of computing is strongly related to temporal semantics of the language, and timeliness of live execution despite heterogeneous nature of time in the two mediums.
FREEOpen to the PublicRyan Carter : Programming Interactive Musical Systems with RTcmix
Date:Wed, 04/09/2014 - 5:15pm - 7:00pmLocation:CCRMA Classroom, The Knoll 2nd floor, Rm 217Event Type:Colloquium
Recent work in RTcmix (an open-source digital signal processing and sound synthesis language implemented in C/C++) facilitates flexible and interactive audio integration for a variety of applications. Composer and programmer Ryan Carter will present two recent projects: iMonkeypants (an iOS app album of algorithmically generated, interactive compositions) and Headless Monkey Attack (an alternately solo or collaborative performance project for video game controller and improvising musicians).
Open to the PublicGeorg Hajdu : Audio-based Composition
Date:Wed, 04/02/2014 - 5:15pm - 7:00pmLocation:Rm217, CCRMA Classroom (2nd floor)Event Type:Colloquium
Audio-based composition is a notion that encompasses novel approaches in the field of composition where recorded sounds serve as the basis for a symbolic composition process—spectral composition being an example of such an approach. Over the past 20 years, I have devised a number of strategies and software environments which enable me to transform audio material into compositions such as in my opera Der Sprung and my pieces Schwer...unheimlich schwer, Swan Song, and noiwont.
Open to the PublicAnssi Klapuri - Gamified musical instrument learning: music processing techniques and learning curve optimization
Date:Wed, 03/19/2014 - 5:15pm - 7:00pmLocation:Rm 217, CCRMA classroom, 660 Lomita Drive, StanfordEvent Type:ColloquiumPlaying a musical instrument and playing video games share certain similarities as activities. That has enabled successful music-oriented games such as Rock Band or Guitar Hero, but even more importantly, gamified e-learning applications seem to have particularly high potential for learning certain aspects of musical instrument skills. This talk shares experiences from developing the game GuitarBots, where any real guitar is used as a game controller and the microphone signal is analyzed to figure out the user’s actions.
