Making Speech Content Sound Better

Date: 
Fri, 05/08/2015 - 11:30am - 1:00pm
Location: 
CCRMA Seminar Room
Event Type: 
Hearing Seminar
CCRMA alumnus and Adobe Researcher, Gautham Mysore will lead Friday’s Hearing Seminar with a discussion about how we can improve the quality of audio. Professional quality audio is not trivial to create. Can we build tools that make it easier?

Last week at the CCRMA Hearing Seminar we talked about how to measure the quality of a speech signal. This week we talk about how to make it sound better.

Who: Gautham Mysore
What: Making Speech Content Better
When: Friday May 8 at 11:30AM
Where: CCRMA Seminar Room
Why: Because better audio quality is always better

Naomi Harte - ViSQOL, An objective measure for speech quality

Date: 
Fri, 05/01/2015 - 11:30am - 1:00pm
Location: 
CCRMA Seminar Room (Top Floor of the Knoll)
Event Type: 
Hearing Seminar
How do humans judge perceptual quality of a signal? It’s easy to measure mean-squared error, but that is not how the brain measures quality—that would be too easy. Instead, we want to look inside the brain to see how sound is encoded. This problem is important as we build more devices that process sound and we need to assess whether they are doing a good job. Naomi’s work addresses the problem when we have access to the original and the modified sound. It’s an improvement over the PESQ and POLQA work, if you are familiar with the area.

Acoustic Source Localization in Wireless Sensor Networks: Model and Numerical Algorithm

DSP Seminar

Acoustic Source Localization in Wireless Sensor Networks: Model and Numerical Algorithm

Abstract: Jianhua Yuan will present a series of techniques, based upon the energy based acoustic features, to locate a sound source given measurements of the sound field. For wireless ad hoc sensor network applications, energy based acoustic features is an appropriate choice since the acoustic power emitted by targets, such as moving vehicles usually varies slowly with respect to time. In this approach, mathematical models and new numerical methods may be used to yield higher accuracy in terms of source location estimates compared to the earlier method.

Application of Acoustics for Underwater ROVs

Date: 
Wed, 04/29/2015 - 5:15pm - 7:00pm
Location: 
CCRMA Classroom
Event Type: 
Colloquium

Signaling and navigating in the underwater world presents challenges for traditional approaches such as radio waves and light. Both are readily absorbed in water. Light also tends to scatter and reflect over short distances. Sound waves are much more adaptable to use in this world. While they also present challenges – especially absorption and reflection – they can be used effectively over much greater distances in the order of kilometers.
