IRCAM will host the IASIS research group on Thursday, November 13, 2025. The theme of the day will be: "Emerging topics in audio signal processing: ecoacoustics, urban acoustics, industrial acoustics, medical acoustics."
Ethology, ecology, urban geography, industrial engineering, and biomedical engineering are all disciplines that value sound as information. Long limited to speech and music signals alone, audio signal processing is finding compelling applications for instrumentation in these disciplines. In turn, it is fueled by new challenges in fundamental research. This is evidenced, among other things, by increasingly autonomous and adaptive in situ acoustic sensors; a revival of statistical and geometric methods for time-frequency; and the invention of analysis and synthesis techniques based on unsupervised or minimally supervised learning.
It is in this context that we intend to provide a progress report on work on sounds other than speech and music. These « emerging topics » include, but are not limited to, ecoacoustics, urban acoustics, industrial acoustics, and medical acoustics. The invited speakers will provide an overview of the main issues inherent in these fields while striving to be accessible to the IASIS community as a whole.
