What is this challenge about? A public evaluation on the performance of systems dealing with two important subtasks in Computational Auditory Scene Analysis: the classification of acoustic scenes and the detection of acoustic events. Main challenge aims: • Help the research community move a step forward in better defining the specific tasks. • Offer a(More)
—In this article we present an account of the state-of-the-art in acoustic scene classification (ASC), the task of classifying environments from the sounds they produce. Starting from a historical review of previous research in this area, we define a general framework for ASC and present different implementations of its components. We then describe a range(More)
—We describe a non-parametric estimator for the differential entropy of a multidimensional distribution, given a limited set of data points, by a recursive rectilinear partitioning. The estimator uses an adaptive partitioning method and runs in Θ N log N time, with low memory requirements. In experiments using known distributions, the estimator is several(More)
Automatic species classification of birds from their sound is a computational tool of increasing importance in ecology, conservation monitoring and vocal communication studies. To make classification useful in practice, it is crucial to improve its accuracy while ensuring that it can run at big data scales. Many approaches use acoustic measures based on(More)
We describe a new method for preprocessing STFT phase-vocoder frames for improved performance in real-time onset detection, which we term " adaptive whitening ". The procedure involves normalising the magnitude of each bin according to a recent maximum value for that bin, with the aim of allowing each bin to achieve a similar dynamic range over time, which(More)
Live music-making using interactive systems is not completely amenable to traditional HCI evaluation metrics such as task-completion rates. In this paper we discuss quantitative and qualitative approaches which provide opportunities to evaluate the music-making interaction, accounting for aspects which cannot be directly measured or expressed numerically,(More)
An increasing number of researchers work in computational auditory scene analysis (CASA). However, a set of tasks, each with a well-defined evaluation framework and commonly used datasets do not yet exist. Thus, it is difficult for results and algorithms to be compared fairly, which hinders research on the field. In this paper we will introduce a(More)
This technical report reviews the state of the art in machine recognition of UK birdsong, primarily for an audience of music informatics researchers. It briefly describes the signal properties and variability of birdsong, before surveying automatic birdsong recognition methods in the published literature, as well as available software implementations.
