Using the Sound Description Interchange Format within the SMS Applications

Abstract

Recently, we have seen an increased use and support of the Sound Description Interchange Format (SDIF), among which the integration of SDIF in widely used environments such as MAX/MSP (Wright, Dudas, Khoury, Wang, Zicarelli, 1999) and MPEG-4 (Wright, Scheirer, 1999). To follow and encourage this trend, we have added support for importing and exporting SDIF files in the latest version of the SMS applications, a group of applications for spectrum-modeling analysis and synthesis. In this paper we discuss the use of the SDIF standard in the SMS applications. We give a brief introduction to SMS and SDIF, and examine the features and limitations found in the SDIF standard when used to represent the SMS analysis data. We also present an application for the graphical visualization of the SDIF data as extracted from SMS files, similar to the one used in the SMS graphical tools.
