In this paper a novel signal subspace method for speech enhancement is proposed. The algorithm is derived from the filterbank interpretation of the truncated (quotient) singular value decomposition (T(Q)SVD) algorithm. We derive a recursive version of this algorithm which results in a recursively updated eigenfilterbank. The proposed method benefits from a low system delay and a low amount of m...
Abstract: We show that music is represented by fluctuations away from the minimum path through statistical space. Our key idea is to envision music as the evolution of a non-equilibrium system and to construct probability distribution functions (PDFs) from musical instrument digital interface (MIDI) files of classical compositions. Classical music is then viewed through the lens of generalized ...
A new method for analyzing audio signals in the context of musical transcription is described. It consists of a framebased expansion of the signal over a multi-scale time-frequency dictionary with a set of logarithmic discrete frequencies. This method, based on the Matching Pursuit algorithm, provides the same frequency resolution as a constantQ filter-bank, but with a better time resolution, e...
This paper presents real-time musical applications using the IRCAM Signal Processing Workstation which make use of FFT/IFFT-based resynthesis for timbral transformation in a compositional context. An intuitive and straightforward user interface, intended for use by musicians, has been developed by the authors in the Max programming environment. Techniques for filtering, cross-synthesis, noise r...
Spectral models provide ways to manipulate musical audio signals that can be both powerful and intuitive, but high-level control is often required in order to provide flexible real-time control over the potentially large parameter set. This paper introduces Metamorph, a new open source library for high-level sound transformation. We describe the real-time sinusoids plus noise plus transients mo...
form of noise, but evidence is accumulating to show that listening to it can lead to pronounced physiological and emotional responses. In a recent article, Trainor et al. have shown that specific aspects of musical structure are processed automatically in the human brain, raising the question of whether our response to music has specifically evolved or merely occurs as a side-effect of neural a...
Co-located tabletop tangible user interfaces (TUIs) for music performance are known for promoting multi-player collaboration with a shared interface, yet it is still unclear how to best support the awareness of the workspace in terms of understanding individual actions and the other group members actions, in parallel. In this paper, we investigate the effects of providing auditory feedback usin...
In this paper a new method for pitch estimation enhancement was presented. Pitch estimation methods are widely used for extracting musical data from digital signal. A brief review of these methods is included in the paper. However, since processed signal may contain noise and distortions, the estimation results can be erroneous. The proposed method was developed in order to override disadvantag...
The purpose of this study is to investigate how humans interpret musical scores expressively, and then design machines that sing like humans. We consider six factors that have a strong influence on the expression of human singing. The factors are related to the acoustic, phonetic, and musical features of a real singing signal. Given real singing voices recorded following the MIDI scores and lyr...
Songs are representation of audio signal and musical instruments. An audio signal separation system should be able to identify different audio signals such as speech, background noise and music. In a song the singing voice provides useful information regarding pitch range, music content, music tempo and rhythm. An automatic singing voice separation system is used for attenuating or removing the...
