Extended SDIF types for Audio Descriptors

This page contains a set of resources concerning the use of the SDIF format for storing and transmitting general audio features. These will be usually generated in the feature extraction stage of an audio content analysis application, such as indexing, segmentation, clustering or retrieval-by-similarity. Type declarations for a wide range of short-time features and a set of temporal feature integration methods (called temporal modelings) are provided.
