  • a computational study on outliers in world music
    PLOS ONE, 2017
    Co-Authors: Maria Panteli, Emmanouil Benetos, Simon Dixon
    Abstract:

    The comparative analysis of world music cultures has been the focus of several ethnomusicological studies in the last century. With the advances of Music Information Retrieval and the increased accessibility of Sound Archives, large-scale analysis of world music with computational tools is today feasible. We investigate music similarity in a corpus of 8200 recordings of folk and traditional music from 137 countries around the world. In particular, we aim to identify music recordings that are most distinct compared to the rest of our corpus. We refer to these recordings as ‘outliers’. We use signal processing tools to extract music information from audio recordings, data mining to quantify similarity and detect outliers, and spatial statistics to account for geographical correlation. Our findings suggest that Botswana is the country with the most distinct recordings in the corpus and China is the country with the most distinct recordings when considering spatial correlation. Our analysis includes a comparison of musical attributes and styles that contribute to the ‘uniqueness’ of the music of each country.

  • Vocalizations of the rare and flagship species Pharomachrus mocinno (Aves: Trogonidae): implications for its taxonomy, evolution and conservation
    Bioacoustics, 2019
    Co-Authors: Pablo Bolaños-sittler, Jérôme Sueur, Jérome Fuchs, Thierry Aubin
    Abstract:

    The Resplendent Quetzal Pharomachrus mocinno is a rare Neotropical bird included in the IUCN red list as Near Threatened. Fragmentation of its habitat, the cloud forest, is considered as the principal threat. Two subspecies are currently recognised but genetic and morphometric studies suggested they could be considered as full species. We assessed whether male vocalisation would support a species delimitation hypothesis. We recorded in the field and downloaded from Sound Archives vocalisation of 57 individuals from 30 different localities distributed in 11 countries. We estimated the acoustic differences of all the Pharomachrus taxa with multivariate analyses and machine learning techniques. Our results show vocal differences between P. m. mocinno and P. m. costaricensis that could have a molecular basis, potentially due to genetic drift developed during the more than three million years of separation of P. m. mocinno (from Mexico to Nicaragua) and P. m. costaricensis (Costa Rica and Panama). We therefore suggest that P. mocinno could potentially be divided into two species. A possible separation of these taxa into two species could have important consequences for the conservation status of the Resplendent Quetzals, and redirect conservation efforts for these taxa.

  • For Science, Broadcasting, and Conservation: Wildlife Recording, the BBC, and the Consolidation of a British Library of Wildlife Sounds.
    Technology and Culture, 2019
    Co-Authors: Joeri Bruyninckx
    Abstract:

    After World War II, wildlife recordists and bioacousticians took advantage of advances in electronics and acoustics to collect, store, and analyze recordings of animal vocalizations, leading to the establishment and expansion of numerous wildlife Sound Archives worldwide. This article traces the technological, organizational, and social arrangements that transformed a private collection of recordings by wildlife recordist Ludwig Koch in the 1930s into one of the largest Sound Archives of its kind. It argues that this Sound archive was consolidated through the collective efforts of a recording community-an unlikely alliance of academic biologists, commercial and amateur hobby recordists, and the public service broadcaster British Broadcasting Corporation (BBC), each with a stake in the development, use, and popularization of wildlife recordings. Zooming in on the integration of British naturalists with the BBC, the article shows how, despite scientists' oft-noted suspicion of the media, these parties developed a mutually beneficial association.
