Obtaining Binaural Room Impulse Responses from B-Format Impulse Responses

Christof Faller, Fritz Menzer

Given a set of head related transfer functions (HRTFs) and a room impulse response measured with a Soundfield microphone, the proposed technique computes binaural room impulse responses (BRIRs) which are similar to binaural room impulse responses that woul ...

Role Recognition in Broadcast News Using Social Network Analysis and Duration Distribution Modeling

Alessandro Vinciarelli

This paper presents two approaches for speaker role recognition in multiparty audio recordings. The experiments are performed over a corpus of 96 radio bulletins corresponding to roughly 19 hours of material. Each recording involves, on average, eleven spe ...

Sociometry Based Multiparty Audio Recordings Segmentation

Alessandro Vinciarelli

This paper shows how Social Network Analysis, the sociological domain studying the interaction between people in specific social environments, can be used to assign roles to different speakers in multiparty recordings. The experiments presented in this wor ...

Realization and characterization of magnetic multilayer for MFM tips

High resolution magnetic force microscopy plays an important role in the development of magnetic data storage media. Particularly the envisioned increase of the storage density to 1TBit per sqinch within the next five years requires an ongoing development ...

Room impulse responses measurement using a moving microphone

Martin Vetterli, Luciano Sbaiz, Thibaut Ajdler

In this paper, we present a technique to record a large set of room impulse responses using a microphone moving along a tra jectory. The technique processes the signal recorded by the microphone to reconstruct the signals that would have been recorded at a ...

Comparison of the recording dynamics of phenanthrenequinone-doped poly(methyl methacrylate) materials

Demetri Psaltis

The comparison between the NCTU and Caltech PQ-PMMA material shows that the difference in their behavior lies in the different concentration of residual MMA in the samples. Experimental evidence shows that during recording, PQ molecules attach to MMA but n ...

Localized holographic recording in doubly doped lithium niobate

Demetri Psaltis

In:holographic data storage, pages of information are overlapped in the volume of the recording medium. Due to destructive read-out of holograms in photorefractive crystals such as LiNbO3:Fe, holograms are recorded with an exposure schedule in order-to equ ...

Diffraction efficiency of localized holograms in doubly doped LiNbo(3) crystals

Demetri Psaltis

The diffraction efficiency of M holograms superimposed in the volume of the recording medium is proportional to 1/M-2, me present a method, based on nondestructive localized holograms in a doubly doped LiNbO3 crystal, that allows us to also record M hologr ...

Localized holographic recording in doubly doped lithium niobate

Demetri Psaltis

Persistent holograms are recorded locally with red light in a LiNbO3 crystal doped with Mg and Fe. Selective erasure is realized by use of a focused UV sensitizing light. We demonstrate the recording of 50 localized images as well as selective erasure in a ...
