Upcoming Events

Audio Quality - How Much is Necessary?

Date: 
Fri, 02/03/2023 - 10:30am - 12:00pm
Location: 
CCRMA Stage (Top floor)
Event Type: 
Hearing Seminar
How much do you worry about audio quality?  Do you ever have high-enough quality?  Does anybody care about audio quality? What is audio quality?

I'm very happy to announce a special Hearing Seminar on audio quality. Join us for a panel of distinguished audio experts who will talk about how they perceive audio, when is the quality high enough, and how do we define quality. Come be part of the discussion.

Adaptive and interactive machine listening with minimal supervision

Date: 
Fri, 02/10/2023 - 4:30pm - 5:20pm
Location: 
CCRMA Classroom [Knoll 217]
Event Type: 
DSP Seminar
Abstract: Nowadays deep learning-based approaches have become popular tools and achieved promising results in machine listening. However, a deep model that generalizes well needs to be trained on a large amount of labeled data. Rare, fine-grained, or newly emerged classes (e.g. a rare musical instrument or a new sound effect) where large-scale data collection is hard or simply impossible are often considered out-of-vocabulary and unsupported by machine listening systems. In this thesis work, we aim to provide new perspectives and approaches to machine listening tasks with limited labeled data. Specifically, we focus on algorithms that are designed to work with few labeled data (e.g. few-shot learning) and incorporate human input to guide the machine.

The Furies: A Laptopera

Date: 
Fri, 11/11/2022 - 7:30pm - 9:00pm
Date: 
Sat, 11/12/2022 - 7:30pm - 9:00pm
Date: 
Sun, 11/13/2022 - 4:00pm - 5:30pm
Location: 
CCRMA Stage / CCRMA LIVE
Event Type: 
Concert
The Stanford Laptop Orchestra (SLOrk) presents the first-ever "laptopera". The Furies: A Laptopera is a retelling of the Greek tragedy Electra. Blending a number of versions of the Electra story including works by Aeschylus, Sophocles, Euripides, and Jean Paul Sartre, this retelling explores central questions regarding how communities escape from cycles of violence, the role of guilt and shame in community identity, personal responsibility, how justice interfaces with cycles of violence, and redemption. The artistic medium of the laptop orchestra both serves to recast the traditional instrumental role in a new kind of operatic medium (the “laptopera”) that reimagines the potential of instrument building to support dramatic elements and character relationships—while simultaneously positing critical questions about technology in our lives presently, both in its promise to help us flourish and in its perils to perpetuate and amplify the existing cycles of violence in our world today.

Feedback Delay Networks for Artificial Reverberation

Date: 
Fri, 11/11/2022 - 12:00pm - 12:50pm
Location: 
Zoom
Event Type: 
DSP Seminar
Abstract: Feedback delay networks (FDNs) are recursive filters widely used for artificial reverberation and decorrelation. While vast literature exists on a wide variety of reverb topologies, FDNs provide a unifying framework to design and analyze delay-based reverberators. This talk reviews recent advancements in the FDN theory, such as losslessness, modal and echo representations, and MIMO allpass properties and decorrelation. Many extensions to the FDN were proposed, including time-varying matrices, scattering matrices, high-order attenuation filters, directional reverberation, and coupled room reverberators.

Takako Fujioka - What I did during the pandemic

Date: 
Fri, 11/11/2022 - 10:30am - 12:00pm
Location: 
CCRMA Seminar Room
Event Type: 
Hearing Seminar
Prof. Takako Fujioka continues the Hearing Seminar series “What I did during my pandemic” with an update on her work on understanding the dynamics of ensembles and improvisation.

This is starting to be a theme: How do we take apart and analyze dynamic systems?  In Prof. Fujioka's case, two or more players have their own goals and timing, but must cooperate for the greater good.

Congratulations Guggenheim Fellows Jonathan Berger and Ge Wang!

 

Jonathan Berger's "My Lai" In the News

All kinds of new buzz in being generated by our own Jonathan Berger's latest opera My Lai. Congratulations, Jonathan and the Kronos Quartet!

"In My Lai, a monodrama for tenor, string quartet, and Vietnamese instruments, composer Jonathan Berger had countless tragic elements at his disposal... In this immersive performance, we had the sense that, rather than defaulting to the story's obvious tragic details, Berger illuminate a single, more subtle element - the outraged bewilderment we often feel in the face of unimaginable horror."

Sonifying the world: How life's data becomes music

When Chris Chafe translates data into music, listeners sway to the beat of seizing brains, economic swings and smog.

"Unlike sex or hunger, music doesn’t seem absolutely necessary to everyday survival – yet our musical self was forged deep in human history, in the crucible of evolution by the adaptive pressure of the natural world. That’s an insight that has inspired Chris Chafe, Director of Stanford University’s Center for Computer Research in Music and Acoustics (or CCRMA, stylishly pronounced karma).
