François Germain: Towards practical source-independent algorithms using nonnegative matrix factorization

Date: 
Wed, 04/23/2014 - 5:15pm - 7:00pm
Location: 
CCRMA Classroom, The Knoll 2nd floor, Rm 217
Event Type: 
Colloquium
Limitations 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.

Dana Massie - Sample rate conversion with MaxSRC

Date: 
Wed, 04/16/2014 - 5:15pm - 7:00pm
Location: 
CCRMA, 2nd floor, Rm 217
Event 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 Public

José Echeveste: Antescofo, a dynamic language for real-time musician-computer interaction

Date: 
Mon, 04/14/2014 - 5:15pm - 6:45pm
Location: 
CCRMA Classroom, The Knoll 2nd floor, Rm 217
Event 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.

Review: Auditory Hallucinations, Composed

Congratulations to Jonathan Berger for more great reviews of his "Visitations!"

How Music Hijacks Our Perception of Time

Very interesting article by Dr. Jonathan Berger! "One evening, some 40 years ago, I got lost in time. I was at a performance of Schubert’s String Quintet in C major. During the second movement I had the unnerving feeling that time was literally grinding to a halt. The sensation was powerful, visceral, overwhelming. It was a life-changing moment, or, as it felt at the time, a life-changing eon.
 
It has been my goal ever since to compose music that usurps the perceived flow of time and commandeers the sense of how time passes. Although I’ve learned to manipulate subjective time, I still stand in awe of Schubert’s unparalleled power.

Holly Herndon's New Single Named Best New Track on Pitchfork

Congratulations to our own Holly Herndon, once again in the news!

"In reviewing electronic music composer Holly Herndon’s breakout debut, 2012's Movement, we noted her penchant for "Bending one person's voice into phantasmagorias", which continues on her newest, breath-halting single, “Chorus”." Read more, and watch video here...

Turning brain waves into music helps spot seizures

The music is eerie, if not altogether aesthetically pleasing. Like a soundtrack moments before a film's horrifying twist, the sounds of the brain in a state of seizure betrays the plot with little more than a skin-prickling crescendo.
 
This music, the electrical activity of the seizing brain translated to sound, is a merger of art and medicine, the work of Stanford's Dr. Josef Parvizi, an epilepsy specialist, and Chris Chafe, a composer and music researcher. 

Tricking the brain

Most interns don’t deliberately try to deceive executives at their employer’s company, but Dolby intern Jimmy Tobin was asked to do just that.
 
For a reception following a day of meetings for the company’s 90 top leaders, Tobin, a student of symbolic systems at Stanford University, and fellow interns working in the Science Group with Senior Staff Scientist Poppy Crum were asked to create a series of demonstrations of perceptual illusions.
