Hearing Seminars
CCRMA hosts a weekly Hearing seminar (aka Music 319). All areas related to perception are discussed, but the group emphasizes topics that will help us understand how the auditory system works. Speakers are drawn from the group and visitors to the Stanford area. Most attendees are graduate students, faculty, or local researchers interested in psychology, music, engineering, neurophysiology, and linguistics. Stanford students can (optionally) receive credit to attend, by enrolling in Music 319 "Research Seminar on Computational Models of Sound Perception." Meetings are usually from 10:30AM to 12:20 (or so, depending on questions) on Friday mornings in the CCRMA Seminar Room.
The current schedule is announced via a mailing list. To be added to the mailing list, send email to hearing-seminar-request@ccrma.stanford.edu. If you have any questions, please contact Malcolm Slaney at hearing-seminar-admin@ccrma.stanford.edu.

The latest speech enhancement work has the potential to dramatically change the way we hear the world around us. This new work has dramatically improved the quality and latency of these algorithms, and it has the potential to change the way we hear the world around us, whether we have normal hearing or need assistance. These new systems build highly sophisticated models of speech, and can pick out the speech signal from the noise. Oh, yes.FREEOpen to the PublicAlain de Cheveigne on cleaning up brain data for analysis and decoding

Brain signals as measured by EEG, MEG or even ECoG are inherently noisy. Not only are there only a few dozen sensors to measure billions of different neural sources, the electrical environment can change during an experiment. One would like techniques that can pull the signal out of the noise. This can be done with smart forms of noise control, de-trending and signal averaging.Alain de Cheveigne will be at CCRMA on Friday to discuss a panoply of techniques to enable you to find the signals you care about.FREEOpen to the PublicAndrew Oxenham: How far does musical training generalize?

I’m really pleased that Prof. Andrew Oxenham will be here at CCRMA on Friday afternoon to talk about: How far does musical training generalize? This is a special time (3PM) to accommodate his travel schedule. I’m glad we get to welcome him to Stanford.
Andrew has an amazing record studying auditory perception. He has looked at some of the most important problems in psychoacoustics and neurophysiology, with creative and robust experiments.FREEOpen to the PublicLearning Audio Embeddings: From Signal Representation, Audio Transformation to Understanding

Most notably, current approaches abandon the feature calculations, timing models, and language models of yore, replacing them all with a single deep neural network. Amazing, and they work really well, converting millions of hours of speech to text, in all sorts of auditory conditions, in a tiny box that fits in our pockets, for everyday users.

Why: Cool technologies to let us hear what we want to hearFREEOpen to the PublicGerald R Popelka on Wearable Hearing Devices (Hearables)
Date:Fri, 04/26/2019 - 10:30am - 12:00pmLocation:CCRMA Seminar RoomEvent Type:Hearing SeminarI suspect the next technological gold rush is going to be in and around the ears. As our devices become more personal they can make better use of human signals, many of which are easy to measure near the ear. Already, I suspect more of us wear devices in our ears than anywhere else on our bodies. What would you like the next generation of computers to do for you? Better sound? Better vocal assistants? Better physiological monitoring?
Gerald Popelka is a professor in Otolaryngology here at Stanford and has been thinking about what might be possible around the ear. Many efforts towards better hearables have started here in Silicon Valley, and this will be a good opportunity to hear what has been done, what people are thinking about, and what is missing.Open to the PublicAnna Huang on Deep Learning for Music Composition: Generation, Recommendation and Control

Not to mention making self-driving cars possible. Perhaps music is the last problem to solve with DNNs. :-)

Shihab has been studying auditory perception for many decades, and has thought broadly and deeply about many areas of perception. In the past Shihab has helped popularize the spatial-temporal receptive field (STRF) as a measure of cortical activity, and has spearheaded the efforts to do neural decoding, reconstructing audio from neural spikes. Most recently he has been thinking about how music affects our cortex.

But Daniel J. Strauss will be at CCRMA on Friday to talk about "Decoding Spatial Auditory Attention Using a Vestigial Pinna-Orienting System in Humans.” Decoding auditory perception from brain signals is certainly one of the more interesting directions for auditory research. At ARO earlier this year in Baltimore, there was some interesting research showing that movements of the eyes showed up as a movement in the ear drum. And now Daniel Strauss is visiting from the University of Saarland, and will be talking about how our pinna might reflect our listening intent. Cool!
