Endophytes as source of polypeptide and polyketide antibiotics fengycin and bacillaene

Glazyrina, Julia (2018)

Endophytic bacteria, which populate plant tissues, can influence physiological processes in plants. They also have antagonistic effects against many phytopathogens. Utilization of these bacteria as a biological agent for protection of plants is an environmentally friendly alternative to chemical methods. Moreover, since plants belong to the eukaryotic organisms, antibiotics produced by endophyt...

Apples and oranges : a methodological framework for basic research into audiovisual perception

Maempel, Hans-Joachim (2017)

In recent years, increased efforts have been made to investigate the various aspects of audiovisual perception. In general, highly-specific variables are considered, and specific paradigms and methods are applied. Thus, connecting results of various experiments is not always possible in a systematic manner, and several related research fields still lack comprehensive theories and corresponding ...

The FABIAN head-related transfer function data base

Brinkmann, Fabian ; Lindau, Alexander ; Weinzierl, Stefan ; Geissler, Gunnar ; van de Par, Steven ; Müller-Trapet, Markus ; Opdam, Rob ; Vorländer, Michael (2017-02-09)

This data base includes head-related transfer functions (HRTFs), headphone transfer functions (HpTFs), and 3D-meshes of the FABIAN head and torso simulator. More detailed information is provided in the documentation within the data base.

A Database of Anechoic Microphone Array Measurements of Musical Instruments

Weinzierl, Stefan ; Vorländer, Michael ; Behler, Gottfried ; Brinkmann, Fabian ; Coler, Henrik von ; Detzner, Erik ; Krämer, Johannes ; Lindau, Alexander ; Pollow, Martin ; Schulz, Frank ; Shabtai, Noam R. (2017-04-10)

A collection of 3305 single notes of 41 musical instruments of different historical periods was recorded and analyzed. The database includes the instrument recordings, radiation patterns (directivities), and audio features such as the sound power or spectral centroid along with information about the identity and the making of the instrument and its player. The database can be used in virtual r...

Pitch distributions for individual instruments in the symphonies No. 1-9 of L.v. Beethoven

Quiring, Roman ; Weinzierl, Stefan (2016)

This dataset contains pitch distributions for the symphonies No. 1-9 of Ludwig van Beethoven. Data is available for all symphonies, all movements, and every musical instrument separately. Pitch distributions are represented as histograms in the MIDI pitch range. For transposing instruments, the pitch distributions refer to the sounding, not the written pitch. See the file header for information...

Single-channel and binaural room impulse responses of a 64-channel loudspeaker array for different room configurations

Erbes, Vera ; Geier, Matthias ; Weinzierl, Stefan ; Spors, Sascha (2015-04-21)

The database contains measured single-channel and binaural room impulse responses (RIRs and BRIRs) of a 64-channel loudspeaker array of square shape under varying room acoustical conditions. The measurements have been performed at the Audio Lab of the Institute of Communications Engineering, University of Rostock. The RIRs have been measured at three receiver positions for four different absorb...

Proceedings of the EAA Joint Symposium on Auralization and Ambisonics 2014


In consideration of the remarkable intensity of research in the field of Virtual Acoustics, including different areas such as sound field analysis and synthesis, spatial audio technologies, and room acoustical modeling and auralization, it seemed about time to organize a second international symposium following the model of the first EAA Auralization Symposium initiated in 2009 by the acoustics...

Binaural resynthesis of acoustical environments

Lindau, Alexander (2014-07-08)

Diese Dissertation umfasst eine Sammlung von Veröffentlichungen, die der technischen und perzeptiven Optimierung der binauralen Resynthese akustischer Umgebungen gewidmet sind. Binaurale Resynthese beruht auf der Grundannahme, dass es möglich ist, den auditiven Eindruck einem beliebigen Schallfeld ausgesetzt zu sein, künstlich zu evozieren, wenn es gelingt, den entsprechenden Schalldruckverlauf...

Spatial Audio Quality Inventory (SAQI). Test Manual.

Lindau, Alexander (2014-02-27)

The perceptual evaluation of virtual acoustic environments may be based on overall criteria such as plausibility and authenticity or by using catalogues of more detailed auditory qualities as, e.g., loudness, timbre, localization, etc. However, only the latter will be suitable to reveal specific shortcomings of a simulation under test and allow for a directed technical improvement. To this end ...

Livekonzert und Medienmusik: Eine immersive optoakustische Simulationsumgebung für eine wahrnehmungspsychologische Vergleichsstudie
