Rhythmic Rendering is a compositional approach to organizing sound through the integration of rhythmic matrices and selected audio signal processing routines. In this scheme, signal processing becomes integral to the structure of a musical composition, rather than "sweetening" added globally at the terminal point of an audio chain, as in commercial synthesizers.

Along with investigating similarity metrics between audio material, the topic of robust matching of pairs of audio content has gained wide interest recently. In particular, if this matching process is carried out using a compact representation of the audio content ("audio fingerprint"), it is possible to identify unknown audio material by means of matching it to a database with the fingerprints...

A new method for the objective assessment and prediction of the perceived audio quality is introduced. It represents an expansion of the speech quality measure qC , introduced by Hansen and Kollmeier (2000). It is based on a psychoacoustically validated, quantitative model of the ”effective” peripheral auditory processing by Dau et al. (1996a, 1997a). To evaluate the audio quality of a given di...

While frame-level audio features, e.g. MFCCs, in combination with the bag-of-frames approach have widely and successfully been used, we use a block processing framework in our submission. In general block-level features have the advantage that they can capture more temporal information than BOF approaches can. We introduce two novel spectral patterns, closely related to the spectrum histogram a...

Digital watermarking is an approach to inserting invisible or visible marks into a digital multimedia data for further detection of correct ownership at the later stages. Most of the watermarking techniques focus on image and audio file, and several are related to audio file. The proposed work concentrates on improving the performance of spread spectrum audio watermarking technique. Audio water...

This paper presents the first detailed mathematical analysis of the ripple compensation technique for reducing audio distortion in a class-D amplifier with negative feedback. The amplifier converts a relatively low-frequency audio signal to a high-frequency train of rectangular pulses whose widths are slowly modulated according to the audio signal (pulse-width modulation, PWM). Distortion manif...

It is difficult to understand a multimedia signal without being able to say something about its semantic content or its meaning. This chapter describes two algorithms that help bridge the semantic understanding gap that we have with multimedia. In both cases we represent the semantic content of a multimedia signal as a point in a high-dimensional space. In the first case, we represent the sente...
