  • Loughran, Róisín; Walker, Jacqueline; O'Farrell, Marion; O'Neill, Michael (Springer, 2008)
    This paper examines the use of a number of auditory features in identifying musical instruments. The Temporal Envelope, Centroid, Melfrequency Cepstral Coefficients (MFCCs), Inharmonicity, Spectral Irregularity and ...
  • Loughran, Róisín; Walker, Jacqueline; O'Neill, Michael (2009)
    This study explores the use of genetic algorithms (GA) in optimising feature selection for musical instrument recognition. 95 timbral features were used to classify 3006 musical instrument samples into 5 instrument groups. ...
  • Loughran, Róisín; Walker, Jacqueline; O'Neill, Michael; McDermott, James (Springer, 2012)
    This study uses Genetic Programming (GP) in developing a classi er to distinguish between ve musical instruments. Using only simple arithmetic and boolean operators with 95 features as terminals, a program is developed ...
  • Loughran, Róisín; Walker, Jacqueline; O'Neill, Michael; O'Farrell, Marion (IEEE Computer Society, 2008)
    This study aims to create an automatic musical instrument classifier by extracting audio features from real sample sounds. These features are reduced using Principal Component Analysis and the resultant data is used ...
  • Piccand, Sebastien; O'Neill, Michael; Walker, Jacqueline (IEEE Computer Society, 2008)
  • Piccand, Sébastien; O'Neill, Michael; Walker, Jacqueline (2008)
    Particle swarm has proven to be competitive to other evolutionary algorithms in the field of optimization, and in many cases enables a faster convergence to the ideal solution. However, like any optimization algorithm it ...
  • Kreutzer, Cornelia; Walker, Jacqueline; O'Neill, Michael (International Conference on Audio, Language and Image Processing (ICALIP), 2008)
    We introduce a reduced parameter synthesis model for the spectral synthesis of musical sounds, which preserves the timbre and the naturalness of the musical sound. It also provides large flexibility for the user and reduces ...

  • Piccand, Sebastien; O'Neill, Michael; Walker, Jacqueline (Genetic and Evolutionary Computational Conference (GECCO), 2007)
  • Kreutzer, Cornelia; Walker, Jacqueline; O'Neill, Michael (2008)
    We introduce a time-domain model for the synthesis of attack and release parts of musical sounds. This approach is an extension of a spectral synthesis model we developed: the Parametric Synthesis Model (PSM). The attack ...
  • Loughran, Róisín; Walker, Jacqueline; O'Neill, Michael; O'Farrell, Marion (International Computer Music Association, 2008)
    This paper examines the use of Mel-frequency Cepstral Coefficients in the classification of musical instruments. 2004 piano, violin and flute samples are analysed to get their coefficients. These coefficients are reduced ...
