Tiago Fernandes Tavares, Jayme Garcia Arnal Barbedo, Romis Attux, Amauri Lopes
2013 Journal of the Brazilian Computer Society  
Many techniques have been proposed to solve the problem of automatic music transcription.  ...  The paper is focused on the motivations behind each technique, aiming to serve both as an introduction to the theme and as resource for the development of new solutions for automatic transcription.  ...  The piano-roll related to a particular piece may be visualized in a Cartesian plane, where the y-axis represents the pitch p and the x-axis represents time.  ...

From Nodes to Networks: Evolving Recurrent Neural Networks [article]

Aditya Rawal, Risto Miikkulainen
2018 arXiv   pre-print
The paper also shows how the search process can be speeded up by training an LSTM network to estimate performance of candidate structures, and by encouraging exploration of novel solutions.  ...  Thus, evolutionary design of complex neural network structures promises to improve performance of deep learning architectures beyond human ability to do so.  ...  For instance, Cartesian genetic programming was recently used to achieve state of the art In standard recurrent network, the tree node is repeated several times to create each layer in a multi-layered  ...

Structured audio: creation, transmission, and rendering of parametric sound representations

B.L. Vercoe, W.G. Gardner, E.D. Scheirer
1998 Proceedings of the IEEE  
We present an overview of techniques for transmitting and synthesizing sound represented in structured format, and for creating structured representations from audio waveforms.  ...  Structured audio representations are semantic and symbolic descriptions that are useful for ultralow-bit-rate transmission, flexible synthesis, and perceptually based manipulation and retrieval of sound  ...  First, by transposing the pitch of a sample during playback, a single recording can reproduce a range of notes.  ...

On the evolution of music in a society of self-taught digital creatures

Eduardo Reck Miranda
2003 Digital Creativity  
We devised a Cartesian model to represent a triple of notes; that is, an ordered set of three notes that may or may not sound simultaneously.  ...  When the algorithm arrives at a live cell, its co-ordinates are taken to estimate the triple from a given lowest reference note.  ...  the one that is perceptually most similar pd to include in the repertoire.  ...

ARMAS: Active Reconstruction of Missing Audio Segments [article]

Zohra Cheddad, Abbas Cheddad
2022 arXiv   pre-print
Compared to existing methods, we show improvement in the inpainting performance in terms of signal-to-noise (SNR), the objective difference grade (ODG) and the Hansen's audio quality metric.  ...  This work may trigger interest in optimising this approach and/or transferring it to different domains (i.e., image reconstruction).  ...  [4] , the authors proposed a modern neuro-evolution algorithm, Enhanced Cartesian Genetic Programming Evolved Artificial Neural Network (ECG-PANN), as a predictor of the lost signal samples in realtime  ...

Introduction [chapter]

2016 Music Data Analysis  
The interface between the computer and statistical sciences is increasing, as each discipline seeks to harness the power and resources of the other.  ...  This series aims to foster the integration between the computer sciences and statistical, numerical, and probabilistic methods by publishing a broad range of reference works, textbooks, and handbooks.  ...  While multi-pitch estimation can be applied to any music piece that contains harmonic sounds, chord estimation implies some specific temporal and vertical organization of those pitches.  ...

A Constraint-based Approach for Annotating Music Scores with Gestural Information

Daniele P. Radicioni, Vincenzo Lombardo
2007 Constraints  
Gestural information is thereby crucial for a model of music performance, paired with a model of sound synthesis where this information is applied.  ...  The highly constrained nature of performers gestures makes this task suitable to be modeled via a constraint-based approach, coupled with a strategy aimed at maximizing the gestural comfort of performers  ...  Also, we wish to thank the anonymous referees and the Journal's Editor for their valuable comments and suggestions.  ...
