Rob Maher and Arijit Biswas


The AES has launched a new opportunity to recognize student members who author technical papers. 121st Convention Papers Co-Chairs, Rob Maher (Montana State University) and Christopher J. Struck (Tymphany Corporation) have administered a special AES Student Technical Papers Award Competition based on the preprint manuscripts accepted for the AES technical program in San Francisco. Twenty- eight outstanding student-authored papers were nominated.

The review committee was impressed with the quality of each submission, and faced a difficult task before ultimately selecting the winner, "Perceptually Biased Linear Prediction" by Arijit Biswas (Student & Presenting Author) and Albertus C. den Brinker (Advisor, Philips Research Labs Eindhoven, The Netherlands).

The paper describes a low-complexity technique for linear prediction analysis and synthesis using a perceptually-derived prediction filter. The input signal spectrum is shaped so that the coder's quantization error is effectively masked by the signal itself. 

The winning author, Arijit Biswas, was born in Calcutta, India. He received the Bachelor of Engineering (B.E.) degree in Electronics & Communication Engineering from the Bangalore University, India; and the Master of Science (M.Sc.) degree in Signal Processing from the School of Electrical & Electronic Engineering at the Nanyang Technological University, Singapore, in 2001 and 2002, respectively. Currently, he is pursuing Ph.D. within the Signal Processing Systems Group, Technische Universiteit Eindhoven, The Netherlands. His research interests are mainly in speech and audio signal processing - specifically generic coding of speech and audio, multi-channel audio coding, and digital signa- processing in general. He has been awarded the Postgraduate Manpower Programme scholarship sponsored by the Economic Development Board, Singapore, and DAAD-ABB scholarships sponsored by ABB AG, Germany. He is a student member of the IEEE and the AES.

Mr. Biswas’ Ph.D. project is carried out in collaboration with the Digital Signal Processing Group at Philips Research Labs Eindhoven. He received a special certificate of recognition during the 121st Convention. The manuscript will be published in the Journal of the Audio Engineering Society. 

Nominees for the Student Paper Award were required to meet the following qualifications: 
(a) The paper was accepted for presentation at the AES 121st Convention.
(b) The first author was a student when the work was conducted and the manuscript prepared.
(c) The student author's affiliation listed in the manuscript is an accredited educational institution.
(d) The student will deliver the lecture or poster presentation at the Convention. 


Formed in 1948 by a group of concerned audio engineers, the Audio Engineering Society counts over 12,000 members throughout the U.S., Latin America, Europe, Japan and the Far East. The AES serves as the pivotal force in the exchange and dissemination of technical information for the industry. For additional information on the AES 121st Convention please visit
