Title: Music Genre Classification based on Chord Progression

Presentation abstract:

His research focuses on music genre classification of musical signals based on the chord progressions.  To extract the chord-based features from the musical signals, chroma vector named pitch class profile (PCP) is used. Instead of using chord labeling from the PCP to perform the classification, PCPs are directly used alone with chord progression templates.  Chord progressions templates are vectors which have the same structure of PCPs and they represent the musical knowledge of the common and representative chord patterns of different music genres. He will experiment with more data and enhance the chord classification method.

At the end of meeting, we reportd on progress of our graduation (or master) thesis.

Last meeting report

This post is report of meeting at January 10, 2014.

Next week meeting can not hold because UoA will have preparing for the National Center for University Entrance Examination. So, our next meeting is held on January 16 instead of ordinary meeting with a guest lecture.
Details of this lecture :

  • Place : S8
  • Date : January 16, 2014
  • Time : 13:10 – 14:40

Prof. Julián gives us some advices for writing thesis.
Rules for proof-reading

  • Use of latex is strongly recommend
  • Use American spelling
  • Run the spell-checker! (SERIOUSLY!!)
  • Read what you have written before sending it
  • If you want comments, send a PDF title formatted as single column, double space
  • Integrate previous comments in the current draft

Finally,  Sanuki-kun who is a member of spatial media group, won the encouragement technology of made in Aizu-Wakamatsu prize!
He made a iOS application that is a navigation system with spatial sound.
He went to professor’s office to get some advices for application and presentation. This is a best example to improve research, thesis, presentation, and so on.

Rise and shine: Investigating the influence of height channels on the multichannel audio reproduction

We are pleased to sponsor a seminar next week about spatial sound.
All are welcome.

Date: Thursday, Jan. 16

Location: room S8

Time: 13:10 — 14:40

Speaker: Sungyoung Kim

Affiliation: Electrical, Computer, and Telecommunication Engineering
Department, Rochester Institute of Technology, NY, USA.

In order to provide consumers more enhanced and immersive experience in sound, most of the new multi-channel reproduction formats highlight the significance of height-related information. In this talk, we investigated the influence of height-related room impulse responses when reproduced via various “height-loudspeakers,” including a virtual loudspeaker. Test participants listened to the corresponding sound fields and rated their perceived quality in terms of spaciousness and integrity. The results showed that perceived quality was affected by height loudspeaker positions but not by height signals, which was convolved with specific room impulse responses.

Sungyoung Kim received a B.S. degree from Sogang University, Korea, in 1996, and a Master of Music and Ph.D. degree from McGill University, Canada, in 2006 and 2009 respectively. His professional work experiences include recording/balance engineer at Korea Broadcasting System (KBS), Seoul, Korea (1995–2001) and research associate at Yamaha Corporation (2007–2012), Hamamatsu, Japan. He is now an assistant professor at Electrical, Computer, and Telecommunication Engineering Department, Rochester Institute of Technology. His research interests are spatial audio and human perception, and efficient ear training methods. He is a member of the IEEE and Audio Engineering Society (AES).
