In the recently proposed latent perceptual indexing of audio, a collection of clips is indexed using unit-document frequency measures between a set of reference clusters as units and the clips as the documents. The reference units are derived by clustering the bag-of-feature vectors extracted from the whole audio library using an unsupervised clustering technique. Indexing is achieved through reduced-rank...
A new chroma-based dynamic feature vector is proposed inspired by psychophysical observations that the human auditory system detects reltative pitch changes rather than absolute pitch values. The proposed chroma-based dynamic feature vector describes the relative pitch change intervals. The utility of the proposed feature vector incorporated with a music fingerprint extraction algorithm is experimentally...
Using the recently proposed framework for latent perceptual indexing of audio clips, we present classification of whole clips categorized by two schemes: high-level semantic labels and the mid-level perceptually motivated onomatopoeia labels. First, feature-vectors extracted from the clips in the database are grouped into reference clusters using an unsupervised clustering technique. A unit-document...
The lack of publicly available annotated databases is one of the major barriers to research advances on emotional information processing. In this contribution we present a recently collected database of spontaneous emotional speech in German which is being made available to the research community. The database consists of 12 hours of audio-visual recordings of the German TV talk show ldquoVera am...
We present a descriptive approach for analyzing audio scenes that can comprise a mixture of audio sources. We apply this method to segment popular music songs into vocal and non-vocal sections. Unlike existing methods that directly rely on within-class feature similarities of acoustic sources, the proposed data-driven system is based on a training set where the acoustic sources are grouped by their...
