NEU: Forschung kann auch Emotionen | Kooperation mit dem Sinfonieorchester Aachen

Nutzungshinweise:

Bitte benutzen sie Kopfhörer für optimalen Sound.
Auf mobilen Geräten: Wischen Sie mit dem Finger über das Video um den Betrachtungswinkel zu verändern.
Auf PCs: Nutzen Sie den gedrückten Mauszeiger zum Ändern des Betrachtungswinkels.

Bei der Aufzeichnung der Videos mit binauralem Ton wurden wir freundlicherweise von der HEAD acoustics GmbH durch die Leihgabe von drei HMS IV.1 Kunstköpfen unterstützt.

Recording the Aachen Symphony Orchestra in 3D: For the new IKS|Lab we captured our first 360° videos with spatial sound. We got the great opportunity to join the Aachen Symphony Orchestra during different rehearsals and concerts to record professional orchestral music.
Spatial Audio Acquisition & Processing: At IKS, we contribute to the research in Spatial Audio Processing. The term refers to the processing of multiple signals which are a representation of observations of a sound field. It comprises the sampling of the field, the mathematical signal representation, the analysis, modification and synthesis of signals, and perceptual aspects of aural localization.
Active Noise Control: Active Noise Cancellation (ANC) is based on the principle of anti-phase compensation. A cancellation signal is emitted, which superposes and cancels out existing noise. The cancellation signal is created by filtering a reference signal with a filter. This filter is either adjusted online by an adaptive algorithm or optimized in advance by methods of control theory. We are specifically working on the application of ANC for headphones and hearing aids.
Multi-Channel Upmix: Stereo to multi-channel upmix is a technique used to adapt stereo audio signals to playback setups with multiple speakers. Modern approaches make use of dynamic signal decomposition in direct and diffuse parts and spatial rendering methods.
Multi-Channel System Identification: Algorithm to perform fast identification and tracking of time-variant, linear multi-channel systems. Dynamic measurement of continuous-azimuth HRIRs
Immersive Audio Coding: New concepts in Spatial Audio Acquisition and Processing require new concepts for the representation and data efficient transmission of spatial audio. Channel-based formats such as 5.1 are not suited for a flexible adaptation to various playback setups. Therefore, concepts such as Spatial Audio Object Coding (SAOC) and Higher Order Ambisonic (HOA) are needed for modern audio codecs such as MPEG-H 3D Audio.
