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 5:15 - 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
François 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.
Open to the PublicMarcus Schmickler: Politics of Frequency - Colloqium and Concert
Date:Thu, 03/06/2014 - 5:15pm - 9:00pmLocation:CCRMA StageEvent Type:Colloquium
5:15pm: Schmickler’s talk will give an introduction to the piece "Poiltiken der Frequenz" (Politics of Frequency). Following an hypothesis "Music and Economics share a fundamental object: numbers." Schmickler’s project "Poiltiken der Frequenz" circles around the acoustic rendering of number concepts. Inspired by Alain Badiou’s Le Nombre et les Nombres, the piece attempts to question the apparent immediacy of numbers that allow calculation to govern today’s economy, social sciences and everyday life.
FREEOpen to the PublicJohn La Grou -Studio of the Future: 2020–2050
Date:Wed, 02/26/2014 - 5:15pm - 7:00pmLocation:CCRMA Classroom, The Knoll 2nd floor, Rm 217Event Type:ColloquiumA brief look at the evolution of audio electronics, a theory of innovation, and a sweeping vision for the next forty years of audio production technology.
Open to the PublicMarc Weidenbaum: Cultural Afterlife Is a Form of Change: Two Decades of Aphex Twin's Selected Ambient Works Volume II
Date:Wed, 02/19/2014 - 5:15pm - 7:00pmLocation:Knoll ClassroomEvent Type:ColloquiumThe Talk: Marc Weidenbaum will discuss his new book in the 33 1/3 series published by Bloomsbury, Selected Ambient Works Volume II, which is about the Aphex Twin (aka Richard D. James) album by that name. He will focus on the "cultural afterlife" that the album has experienced in the two decades since its initial release on the Warp and Sire labels in 1994. Faithful to Brian Eno’s definition of ambient music, Selected Ambient Works Volume II was intentionally functional: it furnished chill-out rooms, the sanctuaries amid intense raves.
FREEOpen to the PublicJack Conte: Unbreaking Content Monetization: Why Ad Revenue Sucks at Making Creators Money
Date:Wed, 02/12/2014 - 5:15pm - 7:00pmLocation:CCRMA ClassroomEvent Type:Colloquium
YouTubers are getting rich from ad revenue, right? Jack Conte's video catalog gets a million hits per month, and that generates less than $50 of ad revenue to help him pay the bills. As an independent musician (and the balder, less attractive half of indie duo Pomplamoose), Jack will be telling us about his robotic music video projects, the currently broken content monetization systems, and the emergence of the Creative Middle Class. If you don't like art (or puppies, or candy... just saying....) then come to learn about Jack's recent startup, Patreon, and its mission to make small business creativity a sustainable endeavor.
