Upcoming Meeting: AES SGS Research Colloquium #10: Recording for Spatial Audio and New Spatial Audio Instruments for Electronic Music & Production

October 19, 2021 at 5:00 pm

Location: Zoom virtual Meeting (5pm Central European Time / Germany time zone)

Moderated by: Prof. Dr. Frank Melchior, Banu Sahin

Speaker(s): Leon Hofmann, Jonas Kieser, Maurice Marvin Strobel

Reproducing the Auditory Width of Individual Acoustic Instruments in Immersive Audio Productions Using a Three-Channel Spot-Microphone Arrangement - Leon Hofmann & Maurice Strobel

This talk presents a coincident spot-microphone arrangement for recording acoustic instruments in the context of immersive audio productions. The developed technique enables reproduction of a single instrument with control of its auditory width in the horizontal and vertical dimension during post-production.

The geometrical arrangement as well as the required post-processing for immersive loudspeaker-based audio productions is discussed. A detailed analysis of the proposed microphone array is provided and a prototypical implementation of a decoding and panning tool will be demonstrated. The purpose of this tool is the intuitive adjustment of the spot-microphone’s signals as well as panning the resulting signals via amplitude panning within a 7+4 speaker layout.

Additionally, a recording of ten individual instruments and two singers with three spot-microphone positions each, was carried out in an anechoic chamber using the new method. The audio files and detailed documentation are provided online for evaluation and further research. An overview of this database as well as the initial findings gathered throughout mixing the 100+ track production for a 7+4 loudspeaker setup are given.

Object-Based Spatial Wavetable Synthesizer - Jonas Kieser

Spatial audio formats have made their way into popular music production. In current workflows, spatialization is mostly part of the post-production process. To unlock the full creative potential of spatial audio, the design of spatial attributes should be considered as part of the composition and sound design stage. One approach for the shift to the composers can be the integration of spatial audio into virtual instruments - for which there are currently hardly any examples. In this presentation, a prototype will be presented, that makes several proposals for the integration of spatial audio into a virtual wavetable synthesizer. The synthesizer generates object-based, format-agnostic spatial audio output with a variety of audio objects. Polyphonic voices and independent wavetable oscillators can be distributed to the audio objects and moved in space through parameters of the synthesis process.

The prototype was evaluated with experts from the fields of composition & sound design as well as post-production. The individual proposals of the implementation were predominantly evaluated positively and detailed feedback will be discussed in the presentation. It became clear that artistic research together with insights from psychoacoustics and innovative designs of virtual instruments are necessary to advance further developments in the field of sound synthesis and spatial audio.

Past Event: AES SGS Research Colloquium #9: Room Acoustic Analysis with the Sound Particle Diffraction Method

September 21, 2021 at 5:00 pm

Location: Zoom virtual Meeting (5pm Central European Time / Germany time zone)

Moderated by: Dr Elena Shabalina

Speaker(s): Dr Thomas Judd

Room acoustics simulation software is an important tool for improving acoustic environments, allowing proposed designs and retrofit options to be assessed in advance. Venues such as concert halls, offices, airports, teaching rooms, restaurants, and bars often have pressing acoustic issues and benefit from a virtual analysis. Commercial software tends to do this with geometrical acoustic techniques such as the sound particle method (akin to ray-tracing) as these provide a suitable compromise between accuracy and run times.

This presentation will review recent developments in this field and discuss interesting issues and challenges that have arisen for us and our customers in the last few years. Schemes for handling diffraction will be considered along with the troublesome topic of treating scattering correctly in these contexts. We’ll look at the different types of room acoustic parameter and discuss their pros and cons. The inter-connected themes of uncertainty analysis and geometrical level-of-detail will be presented along with the question of whether acoustic engineers need to model chairs in their simulations.

Finally, we’ll review some more exotic topics such as auralization, the apparently strange subject of high-performance sound processing on graphics cards, and prospects for using these methods outdoors, e.g. for open-air concerts. I’ll also offer my thoughts and tips on getting results with the greatest efficiency when using these methods and how to avoid trouble.

The Presenter

Thomas Judd - SoundPLAN GmbH

Dr. Thomas Judd is a software developer at SoundPLAN GmbH, specializing in indoor noise and room acoustics. He obtained his MSci and PhD from the University of Nottingham in the UK with a research focus on ultra-cold atoms.

Past Event: AES SGS Research Colloquium #3: From Algorithmic to Neural Beamforming - Two Approaches to Multichannel Speech Separation in Pro Audio

February 16, 2021 at 5:00 pm

Location: Zoom virtual Meeting (5pm Central European Time / Germany time zone)

Moderated by: Elena Shabalina - d&b audiotechnik GmbH

Speaker(s): Jonathan D. Ziegler - Institute for Visual Computing, University of Tübingen

Abstract

Human interaction increasingly relies on telecommunication as an addition to or replacement for immediate contact. Remote participation in conferences, sporting events, or concerts is more common than ever, and with current global restrictions on in-person contact, this has become an inevitable part of many people’s reality. The work presented here aims at improving these encounters by enhancing the auditory experience. Augmenting fidelity and intelligibility can increase the perceived quality and enjoyability of such actions and potentially raise acceptance for modern forms of remote experiences. Two approaches to automatic source localization and multichannel signal enhancement are investigated for applications ranging from small conferences to large arenas.
Three first-order microphones of fixed relative position and orientation are used to create a compact, reactive tracking and beamforming algorithm, capable of producing pristine audio signals in small and mid-sized acoustic environments. With inaudible beam steering and a highly linear frequency response, this system aims at providing an alternative to manually operated shotgun microphones or sets of individual spot microphones, applicable in broadcast, live events, and teleconferencing or for human-computer interaction.
Multiple microphones with unknown spatial distribution are combined to create a large-aperture array using an end-to-end Deep Learning approach. This method combines state-of-the-art single-channel signal separation networks with adaptive, domain-specific channel alignment. The Neural Beamformer is capable of learning to extract detailed spatial relations of channels with respect to a learned signal type, such as speech, and to apply appropriate corrections in order to align the signals. This creates an adaptive beamformer for microphones spaced on the order of up to 100 m.

The Presenter

Jonathan D. Ziegler is a PhD student at the Wilhelm Schickard Institute for Visual Computing at the Eberhard Karls University in Tübingen, focusing on deep learning and audio signal processing. He received his degree in Physics from the Karlsruhe Institute of Technology. In the past five years he has completed two large research projects as part of the Institute for Applied Artificial Intelligence at the Stuttgart Media University, closely collaborating with industry leaders in microphone and console design. In 2020, he joined the console manufacturer Lawo as a machine learning engineer, working on model optimization for real-time applications. He has more than fourteen years of experience as a musician and producer, and ran a small recording studio for over ten years.

Past Event: AES SGS Research Colloquium #2: Audio Production in the Context of Stereo-Upmix-Capable Playback Systems

February 2, 2021 at 5:00 pm

Location: Zoom virtual Meeting (5pm Central European Time / Germany time zone)

Moderated by: Elena Shabalina - d&b audiotechnik GmbH

Speaker(s): Lukas Benedicic - FH Joanneum Graz and University of Performing Arts Graz

Abstract

The research work deals with the production of audio content optimized for playback via the Echo Studio Smartspeaker as a case study for stereo-upmix-capable playback systems. The topic of 3D audio is considered one of the most promising within the audio community, but its establishment into the mainstream seems to be a long way off. This 'inertia' could be due to the currently still rather limited accessibility of 3D audio, as this content can usually only be played back via special systems. The vast majority of people still consume audio content in stereo. In order to still be able to offer immersive listening experiences, playback systems such as the Amazon Echo Studio or Soundbars such as those from Sennheiser use stereo upmix technologies, which means that no special audio formats are required. The goal of this work is to find out how to best use these technologies from a production point of view. This will help to determine whether such technologies should be considered in future productions.

The PresenterThe Presenter - Lukas Benedicic

I am a Sound Designer and Musician, currently finishing my studies at the FH Joanneum Graz and the University of Music and Performing Arts Graz.
