Upcoming Events

Naomi Harte - ViSWOL, An objective measure for speech quality

Date: 
Fri, 05/01/2015 - 11:00am - 12:30pm
Location: 
CCRMA Seminar Room (Top Floor of the Knoll)
Event Type: 
Hearing Seminar

This talk gives an overview of ViSQOL – the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a spectro-temporal measure of similarity between a reference and a test speech signal. The metric has been designed to be particularly robust for quality issues associated with Voice over IP (VoIP) transmission. The talk will explore how the original idea for associating visual similarity with spectrogram changes developed. I’ll show results from a full evaluation of the metric against PESQ and POLQA in a range of scenarios, including how it handles VoIP degradations.

Mr. Cable's Low-Fi Reverberator
by Jonathan Abel

A computational structure capable of producing distorted, pitch manipulated reverberation is described.  The distortion is virtually free of intermodulation products, making it appropriate for use with material having dense harmonies.   The pitch manipulation permits large pitch shifts as well as a kind of scrambling of the frequency axis, including an effect similar to pitch inversion.  Sound examples, including distorted room and spring reverberation, two-octave pitch shifting and an inverted guitar, are presented

Raitis Smits - Emerging Techno-Ecological Art Practices - the Poetics of Green Energy

Date: 
Wed, 02/18/2015 - 5:15pm - 6:45pm
Location: 
CCRMA Classroom
Event Type: 
Guest Colloquium
Today we are witnessing the transformation process from new media to post media situation which is characterized not only by equality and convergence of different media technologies but also by emergence of new "techno-ecological" paradigm. Artists, like those from the Renewable Network who once were in vanguard exploring digital frontiers, today are among those who are engaged in the quest for a more sustainable future. By working together with scientists and farmers, urban gardeners and rural communities, media archeologists and future visionaries, the artists are bringing to foreground ecological issues, yet staying rooted in new media.

Moving Auditory EEGs out of the Lab

Date: 
Fri, 02/13/2015 - 11:00am - 12:30pm
Location: 
CCRMA Seminar Room
Event Type: 
Hearing Seminar

It's now time to take EEG out of the lab and into the real world. Our speaker on February 13 will talk about his efforts to build a mobile EEG recording device and validate its performance with an auditory task.  Maarten De Vos received his PhD from KU Leuven (Belgium) and is visiting Stanford for a few months, before heading to a faculty position at Oxford.

His validation experiments are interesting because he describes them as a means of decoding attention.  He's using P300 attention-modulated correlates to measure what people are attending to.  Very interesting.

  Who: Maarten De Vos (University of Oldenberg, Oxford and visiting Stanford)

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.

Stanford scientists build a 'brain stethoscope' to turn seizures into music

When Chris Chafe and Josef Parvizi began transforming recordings of brain activity into music, they did so with artistic aspirations. The professors soon realized, though, that the work could lead to a powerful biofeedback tool for identifying brain patterns associated with seizures. Read more here...
