Prof. Dr.-Ing. Walter Kellermann, FAU Erlangen
What you hear is what you get – still noisy after all these years? 10:45 – 11:05Just as processing of other natural signals, most of audio signal processing essentially aims at removing undesired components from real-word recordings or at avoiding undesired degradation when reproducing originally clean signals. Over the past 60 years, digital audio signal processing developed from adopting the reinvented Fast Fourier Transform for manipulating audio spectra to all-neural algorithms for acoustic signal enhancement and speech and audio coding and synthesis. Along with the dramatic evolution of algorithms and computing power, audio researchers enabled tremendously successful products and thus continuously fueled user expectations and research on evermore challenging tasks. Nevertheless, and fortunately for audio research, the fundamental challenges remain the same …

Broadcast to the SmartPhone – not without Audio 11:10 – 11:30Today´s universal personal media hub is the SmartPhone. Taking advantage of its enormous data processing capabilities, the built-in multi-GigaByte memory and its connectivity to the outside world via WiFi, 4G or 5G cellular networks, and Bluetooth, it serves nearly all media-consumption scenarios conceivable. Well, the screen sizes are limited and high-quality listening requires headphones. In view of the role of SmartPhones and its features, industry forecasts indicate that the large majority of data consumed via the device will be video (and audio mostly to go with it). In view of these predictions: Is there a good reason to enhance the traditional multi-cell cellular networks by an overarching broadcast layer addressing SmartPhones in order to relieve those networks from the video avalanche? The presentation will give an overview of R&D activities in this field, present the state of the art typically called “5G Broadcast” and its possible future enhancements.

Dr. Schuyler Quackenbush, Audio Research Labs
Audio and Standardization in ISO 11:40 – 12:00Dr. Brandenburg has most notably collaborated in the development of the MPEG-1 Layer III, and the MPEG-2 Advanced Audio Coding standards, two of the most widely adopted audio compression standards in the world. This talk will give a technical overview of these two audio compression algorithms. In addition, it will introduce the team of experts that developed the algorithms that resulted in the standards. Finally, it gives a brief view of what is happening now in Audio standardization: MPEG-I Immersive Audio for Virtual and Augmented Reality.

Never Enough: How to Deal with Data Scarcity in Industrial Sound Analysis 12:05 – 12:25Industrial Sound Analysis (ISA) is an emerging field in industrial quality control, where the sound emitted by machines or production processes is analyzed to gain knowledge of their condition. ISA applications include in-line testing, end-of-line testing, and predictive maintenance. Due to the complex acoustic conditions in production facilities, machine learning-based techniques are a promising approach to classify the emitted sound. However, annotating sufficient data to train robust classifiers is often challenging and requires expert knowledge or even product destruction. This talk will demonstrate the potential of state-of-the-art semi-supervised learning when annotated training data is scarce. This training paradigm, which incorporates unlabeled data into the training process, can significantly reduce the required amount of annotated data, ultimately saving costs and resources when building monitoring systems for ISA or other audio classification tasks.

From Ears to Bytes: How Perceptual Audio Coding Transformed the Digital Music Landscape 13:05 – 13:25Have you ever wondered how your MP3 files can pack so much sound into such a small size? Or what sets AAC apart from MP3? The development of perceptual audio coding technologies was a game-changer, enabling the launch of portable music devices and the ubiquity of these technologies in our daily lives - from mobile devices and broadcasting to electronic music distribution. But what made this possible, and where is the technology headed? In this exploration, Dr. Bosi will delve into the significant advancements in audio coding over the past years, and how they have presented new challenges and opened new opportunities.

The Future of the Live Events Industry 14:00 – 14:20We are witnessing a revolutionary shift in the history of live events, leading us all to innovative technology and solutions every day. Live experiences increasingly adapting immersive audiovisual applications, while interactivity enhances the audience engagement. Sustainability becomes a key role in protecting the environment for future generations, that is much more concerning than ever before. Consequently, demanding us to make conscious decisions in event planning to minimize waste, emissions and pollution. This is the most critical times for our planet and yet also the most exciting times for the development of event technologies. In this talk, the presenter aims to shed a light on how the live events industry might look like in the future, while describing current trends.

Nils Merten, M.Sc., Brandenburg Labs
Sound of the Future: Immersive Audio for Headphones 14:25 – 14:45The creation of an immersive audio experience for headphones has posed enormous challenges to science and industry for decades. Brandenburg Labs takes on these challenges by developing cutting edge algorithms and using the latest research on psychoacoustics, building upon the basic research of universities like TU Ilmenau, TH Köln or Aalto University. A proof-of concept system, shown at fairs and conferences worldwide, demonstrates the lifelike audio experience for headphones. While Brandenburg Labs aims for the consumer market with its headphone systems in the long run, the technology is currently used in music studios for mixing of spatial content and research. By replacing current multichannel systems, Brandenburg Labs enables mixing independent of location and speaker hardware today. The talk will also give an outlook to future applications.
