High order Ambisonic decoding method for irregular loudspeaker arrays
Ambisonics, a sound field synthesis and reproduction technique, has shown promising results in conveying three-dimensional spatialized sound. Ambisonic encodings directly describe the spatial properties of sound fields without reference to the reproduction system. Precise regeneration of a sound field requires a large number of loudspeakers arranged so as to adequately sample all directions; th...
متن کاملAmbisonic Synthesis of Complex Sources
Exterior expansions of complex sound sources are presented as flexible objects for producing Ambisonic soundfield encodings. The sources can be synthesized or recorded directly, rotated and positioned in space. Related techniques can also be used to efficiently add high quality reverberation depending on the orientation and location of the source and listener.
متن کاملLocalization of 3D Ambisonic Recordings and Ambisonic Virtual Sources
The accurate recording and reproduction of real 3D sound environments is still a challenging task. In this paper, the two most established 3D microphones are evaluated: the Soundfield SPS200 and MH Acoustics’ Eigenmike EM32, according to 1 and 4 order Ambisonics. They are compared to virtual encoded sound sources of the same orders in a localization test. For the reproduction, an Ambisonics sys...
متن کاملPrivacy Preserving Energy Management
The improvement of energy efficiency is an important target on all levels of society. It is best achieved on the basis of locally and temporally fine-grained measurement data for identifying unnecessary use of energy. However, at the same time such fine-grained measurements allow deriving information about the persons using the energy. In this paper we describe our work towards a privacy preser...
متن کاملEnergy-Aware H.264 Decoding
The increasing use of more resource-intensive multimedia applications in communication has made it essential to ensure better utilization of available computing resources. At the same time, energy consumption has turned out to be one of the most important resource constraints in modern systems. Digital videos are an important part of multimedia, and a large number of video standards are current...
