Centre for Digital Music PhD student Shubhr Singh will be presenting his recent work on “Local-Higher Order GNNs For Audio Classification And Tagging” as part of the Geometric Deep Learning workshop, taking place on 10-12 June 2024 at the University of Cambridge. The workshop is organised by the EPSRC’s Mathematics for Deep Learning programme grant (m4DL).

Shubhr’s work introduces the Local-Higher Order Graph Neural Network (LHGNN), which stands as a significant step forward in the field of audio classification and tagging, providing a robust framework that leverages graph-based and clustering methodologies to achieve high performance.

On 15-17 June, AIM PhD students will participate in the Audio Engineering Society’s 2024 European Conference (AES Europe 2024). AES is a leading professional body in the field of audio processing. The theme of this year’s European conference is “Echoes of the Past Inspire the Sound of the Future”. All papers will also be published in the Journal of the Audio Engineering Society (JAES).

AIM students will present the following papers at AES 2024:

• Time-of-arrival Estimation and Phase Unwrapping of Head-related Transfer Functions With Integer Linear Programming, by Chin-Yun Yu, Johan Pauwels, and György Fazekas. In this paper, the authors solve two tasks for head-related transfer functions: time-of-arrival and phase unwrapping. They evaluate an algorithm which uses graph-based data structure and integer linear programming – achieving state of the art results.

• The Role of Communication and Reference Songs in the Mixing Process: Insights From Professional Mix Engineers, by Soumya Sai Vanka, Maryam Safi, Jean-Baptiste Rolland, and György Fazekas. The authors identify how context can be incorporated into design of AI-based user-centric auto mixing tools. This is achieved through semi-structured interviews with professionals followed by a questionnaire-based study which corroborates identified themes.

See you all there!

AIM PhD student Shubhr Singh, among other C4DM members, is participating in the organisation of the task on Few-shot Bioacoustic Event Detection as part of the IEEE AASP Challenge on Detection and Classification of Acoustic Scenes and Events (DCASE 2024).

This task addresses a real need from animal researchers by providing a well-defined, constrained yet highly variable domain to evaluate machine learning methodology. It aims to advance the study of audio signal processing and deep learning in the low-resource scenario, particularly in domain adaptation and few-shot learning. Datasets will be released on 1st June 2024, with the challenge deadline being on 15 June 2024.

Can you build a system that detects an animal sound with only 5 examples? Let’s liaise to push the boundary of computational bioacoustics and machine listening!
