    Watermarking is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. The transmission must be possible in spite of subsequent imperceptible alterations (attacks) of the watermarked signal. We propose a unitary approach of watermarking and attack algorithms by defining them in a similar manner, using sets and set mappings. The algorithms are then ... View full abstract»

    It is axiomatic that accessibility should be an integral component of any system, and this component is only now beginning to receive the attention it merits. Where such a component is considered integral to the design process, the resulting system benefits on many different levels. For music production and consumption systems, the 'workaround' nature of traditional accessibility enhancements coul... View full abstract»

    We propose LicenseScript as a new multiset rewriting/logic based language for expressing dynamic conditions of use of digital assets such as music, video or private data. LicenseScript differs from other rights expression languages in that it caters for the intentional but legal manipulation of data. We believe this feature is the answer to providing the flexibility needed to support emerging usag... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (294 KB) | HTML iconHTML

    The goal is to develop a framework of intelligent computer-aided composition based on melodic contours and tabular constraints. Melodic contour is derived from whistling input as a MIDI controller. Tabular constraint is a flexible representation for describing, processing, and synthesizing musical structure of MIDI format music. Based on a given melodic contour, there are two main areas of compute... View full abstract»

    Web based musical discussions are sometimes limited by the fact that most of the applications used (forums, guestbooks etc.) only support textual messages. Although systems with advanced functionalities like file attachments or images and sounds inline inserts are technically possible, very few if any of the existing "off the shelf", freely available systems support them. We propose a generalized ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (443 KB) | HTML iconHTML

    Musical diachrony and synchrony have revealed an incredible variation in musical scales, many of which are implied, lurking in traditional patterns and not adequately transcribed in their projection to the dominant Western music predicates. From antiquity the term "chromatic" was used to determine the coordinates of diversification in terms of psychoacoustic perception of music, and it yielded rel... View full abstract»

    Our approach to generate recommendations for similar artists follows a recent tradition of authors tackling the problem not with content-based audio analysis. Following this novel procedure we rely on the acquisition, filtering and condensing of unstructured text-based information that can be found in the Web. The beauty of this approach lies in the possibility to access so-called cultural metadat... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (212 KB) | HTML iconHTML

    The MusicXML format is designed to be a universal translator for programs that understand common Western musical notation. We have made significant progress towards this goal, with over a dozen programs supporting MusicXML as of June 2003. We describe some of the ways that MusicXML has been used for file interchange, and will demonstrate several scenarios. View full abstract»

  • On the spectral singularities of watermarked audio

    Publication Year: 2003, Page(s):67 - 70
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (291 KB) | HTML iconHTML

    To improve the robustness of watermarking, the spectral singularities resulting from the widely used noise-like author keystream are investigated with audio signals. Because such a keystream distributes its energy abruptly among all frequencies, either the Fourier spectrum or the wavelet spectrum of a watermarked version might become very rough and has many sharp positions, called singularities.
