MUS423 Research Seminars

The CCRMA Music 423 Research Seminar brings graduate students and supervising faculty together for planning and discussion of original research. Students and faculty meet either in small groups or individually, as appropriate for the research topics and interests of the participants. Research carried out is typically presented at the weekly CCRMA Colloquium (if it is of general interest to the CCRMA community) or at a Special DSP Seminar scheduled for that purpose.  In either case, announcements appear on the CCRMA Home Page as Upcoming Events.

Recent DSP Seminars

  • Variable Digital Filters for Musical Purposes

    Location: 
    Classroom, Knoll 217
    Event Type: 
    DSP Seminar

    The first DSP Seminar this quarter will be presented by Hossein Mansour of the Mechanical Engineering Dept. at Simon Fraser.  His presentation will be based on his Master's thesis work in Iran and is entitled "Vibration analysis of Setar, a Persian long necked lute"  Abstract and bio attached.  We hope to see you this week in the CCRMA Classroom, Wed.

  • Graphic Equalizer and Resonant Shelf Filter Design

    Date: 
    Fri, 11/20/2009 - 2:15pm
    Location: 
    CCRMA Classroom, Room 217, The Knoll
    Event Type: 
    DSP Seminar

    This week's DSP Seminar is another double bill:  Dave and I will review a couple filter design methods first presented a few years back at ICMC and AES.  The first method is a graphic equalizer which interpolates prescribed band gains, and the second method produces resonant shelf filters closely matching the transfer function magnitudes of their analog counterparts.  Abstracts follow.  We will meet in the classroom at 2:15 PM.
