Audio Inpainting

Forscher des Instituts für Schallforschung haben in Zusammenarbeit mit Nathanael Perraudin vom Swiss Data Science Center ein Verfahren entwickelt, mit dem Audiosignale, wie zum Beispiel Musik, effizient und automatisch nach lokalen, klanglichen Ähnlichkeiten und Wiederholungen durchsucht werden können. Solche Ähnlichkeiten können zum Beispiel dafür verwendet werden, verlorene Teile eines Musikstücks durch andere, ähnliche Segmente zu ersetzen und so den Datenverlust für Hörer unmerklich zu überdecken. Das Verfahren und seine Anwendung für die zuvor beschriebene Audiorestauration wurde kürzlich in der führenden Fachzeitschrift IEEE/ACM Transactions on Audio, Speech and Language Processing vorgestellt (Links: Artikel / Webpage). 

 

Mehrere Institute der Österreichischen Akademie der Wissenschaften, darunter auch unser Institut für Schallforschung, wollen die Lücke in der Ausbildung zum Thema maschinelles Lernen und moderne Datenwissenschaften schließen und starten mit einer Summer School für Post Graduates.

Die Ausbildung umfasst Grundlagen des maschinellen Lernens, deep learning und Bayes-Statistik sowie entsprechendes Training im Programmieren.
Erklärtes Ziel ist es, das Angebot in Zukunft zu erweitern.

 

Termin:
5. bis 9. August 2019

Full-Time Tenure-Track Junior Group-Leader Position (f/m)

in Acoustic Phonetics

The Acoustics Research Institute (ARI) of the Austrian Academy of Sciences (OeAW) invites applications for a full-time (40h) tenure-track junior group-leader position (m/f) open for researchers in Acoustic Phonetics.

ARI is an interdisciplinary research institution of the OeAW. ARI undertakes fundamental research in psychoacoustics, experimental audiology, acoustic phonetics, computational acoustics, mathematics, and signal processing. A close interaction between ARI's working groups allows innovative research approaches based on the synergy from multidisciplinarity and creates concepts that stimulate the individual research fields. ARI currently employs a staff of approximately 45 people. As part of the OeAW, ARI is focused towards high-impact research comparable to Max-Planck or CNRS institutes.


Acoustic Phonetics at ARI

The research group Acoustic Phonetics has been an important part of the multi-disciplinary research focus of ARI for more than 20 years now. The group is especially renowned for its research on Austrian German, varieties of German and other languages, and its contributions to forensic speech science. The group is an essential part of the inter-disciplinary research environment of the ARI and to the integration of basic phonetic research with signal and speech processing.

While the specific research direction (and the exact group name) is free to be decided by the new group leader within the broad field of phonetics and speech sciences, it should also take account of the existing strengths of this group including the phonetic and phonological description of languages and language varieties as well as their computational modelling, and speaker identification for forensics.

The aims of the group Acoustic Phonetics and its leader are:

  • Having a long-term research perspective in acoustic phonetics by building on the current research foci, as well as developing new ones.
  • Closely collaborating with the other working groups of ARI in interdisciplinary projects.
  • Striving for innovative scientific research expanding ARI's multidisciplinary research portfolio.
  • Aiming to acquire research grants, in order to fund a significant proportion of the group's research with external project funding.

The following resources will be available:

  • Access to all laboratory facilities of ARI.
  • The current working group (one PostDoc, 4 PhD students), partly financed by ongoing third-party funds.
  • One additional PostDoc position to be filled and assigned by the group leader (financed for the first two years).
  • Travelling and additional infrastructure (according to applicant's proposal) in consultation with ARI's director.

Details of Position

The position of group leader of Acoustic Phonetics at ARI can be compared to a tenurable Professorship of Phonetics and Speech Science  (of which there is none in Austria) but with fewer administrative and no strict teaching duties, in order to allow the successful applicant to focus on research. It is a tenure-track position. The salary will be EUR 46254,60 per year (before taxes) according to OeAW's collective agreements. In exceptional cases a higher starting salary is possible. The first contracts will be for up to five years. In the fourth year, the candidate is supposed to apply for an evaluation by the OeAW according to the OeAW evaluation rules. With a positive evaluation decision, the approval by the OeAW's President and Vice President, as well as ARI's director, the position will be tenured.

Main duties and key responsibilities of the successful applicant will be:

  • Scientific research and publications on highest international level.
  • Planning the scientific focus and output of the research group within the multidisciplinary environment of ARI.
  • Managing the research group as an internationally renowned scientific group.
  • Determining, obtaining, and managing the resources to sustain the research program in the long term, to keep or build up the size of the research group (e.g., third-party funding for the new PostDoc starting with year 3).
  • Supervising PhD and master students.
  • Supporting the director of ARI in all organizational issues as part of ARI's steering committee.
  • Being an active member or representative in corresponding networks and societies.
  • Participating in events aimed at introducing the scientific work of the group to the general public, e.g. Long Night of Research or Noise Awareness Day.

Kernsätze in der Mathematik besagen, dass ‚vernünftige‘ Systeme (d.h. Operatoren) als Integrale dargestellt werden können, ähnlich der Matrizendarstellung.
Das erlaubt einen deutlich einfacheren Umgang mit solchen Operatoren. Der klassische Schwartz‘sche Kernsatz aus den 50er Jahren des letzten Jahrhunderts gibt so einen Ansatz für verallgemeinerte Funktionen (d.h. Distributionen).
Ähnliche Aussagen konnten für so genannte Modulationsräume gezeigt werden, die auf einer Klassifikation mittels Zeit-Frequenz Analyse beruhen.

Das Forscherteam des Instituts für Schallforschung und der Fakultät für Mathematik konnten nun überraschend allgemeine Aussagen zeigen. Diese Aussagen können mit Hilfe der Theorie der so genannte Koorbiträume sehr elegant bewiesen werden und verallgemeinern bereits existierende Resultate.
Die Arbeit wurde zur Veröffentlichung in der sehr anerkannten Zeitschrift ‚Transaction of the American Mathematical Society‘ akzeptiert.

 

Die Forschungsgruppen Mathematik und Signalverarbeitung in der Akustik und Psychoakustik und experimentelle Audiologie haben gemeinsam eine Klasse von invertierbaren Filterbänken entwickelt. Der Fokus lag dabei an der Anpassung der Frequenzauflösung an das menschliche Gehör. Durch die Kombination perzeptiver, also an die Wahrnehmung angelehnter, Frequenzskalen mit den Prinzipien der Frametheorie, erlaubt die sogenannte AUDlet Filterbank die effiziente Analyse. Darüberhinaus bietet diese spezielle Kombination die artefaktfreie Synthese von Audiosignalen unter Zuhilfenahme einer Darstellung, die jener unseres auditorischen Systems ähnelt. Die Forschungsergebnisse wurden kürzlich in der Fachzeitschrift Applied Sciences veröffentlicht.
