Labeling of samples is a recurrent and time-consuming task in data analysis and machine learning and yet generally overlooked in terms of visual analytics approaches to improve the process. As the number of tailored applications of learning models increases, it is crucial that more effective approaches to labeling are developed. In this paper, we report the development of a methodology and a framework to support labeling, with an application case as background. The methodology performs visual active learning and label propagation with 2D embeddings as layouts to achieve faster and interactive labeling of samples. The framework is realized through SoundscapeX, a tool to support labeling in soundscape ecology data. We have applied the framework to a set of audio recordings collected for a Long Term Ecological Research Project in the Cantareira-Mantiqueira Corridor (LTER CCM), localized in the transition between northeastern São Paulo state and southern Minas Gerais state in Brazil. We employed a pre-label data set of groups of animals to test the efficacy of the approach. The results showed the best accuracy at 94.58% in the prediction of labeling for birds and insects; and 91.09% for the prediction of the sound event as frogs and insects.

This paper sets out to conduct an embodied and situated aural analysis of what silence in Northern Norway is about, with the aim of bringing forward the background noise. The paper brings together theories on construction of the rural, time-space relations, soundscape ecology, and on affect and power, and it merges academic traditions about how to communicate findings from non-visual biased studies. This interdisciplinary framework provides a novel structure for both analysing material and communicating findings from embodied studies of listening out. The study found that silence in Northern Norway is about not listening to the economy of scale, to the commodification of the natural conditions and the suppression of lifestyles and territory. The paper illustrates how power is an inherent part of listening and how listening is a practice that is enacted to create emotions that are associated with a specific time-space relation.
