Directional emphasis in ambisonics
We describe an ambisonics enhancement method that increases the signal strength in specified directions at low computational cost. The method can be used in a static setup to emphasize the signal arriving from a particular direction or set of directions, much like a spotlight amplifies the visibility of objects. It can also be used in an adaptive arrangement where it sharpens directionality and...
متن کاملAmbisonics Equivalent Panning
In Ambisonics sound is encoded and stored in multichannel sound files and is decoded for playback. In the enand decoding process complicated functions are used. In this paper panning functions equivalent to the result of enand decoding are presented which can be used for real-time panning in an arbitrary high ambisonic order. In the function equivalent to the socalled in-phase decoding the orde...
متن کاملNearfield binaural synthesis and ambisonics.
Ambisonic encodings can be rendered binaurally, as well as for speaker arrays. This process is developed for general high-order Ambisonic encodings of soundfields containing near as well as far sources. For sufficently near sources an error is identified, resulting from the limited field of validity of the freefield harmonic expansion. A modified expansion is derived that can render such source...
متن کاملAmbix - a Suggested Ambisonics Format
Ambisonics is a 3D audio surround rendering and representation approach based on spherical harmonics with loudspeaker independent transmission channels. Although it was developed in the seventies and the techniques are well known, there are disagreements how to normalize, store and exchange Ambisonic data. This paper’s mission is to propose a standard for the Ambisonics community and it should ...
متن کاملAmbisonics User Defined Opcodes for Csound
This text describes the implementation of Ambisonics as user defined opcodes (UDOs) for Csound. The presented package of UDOs includes a basic encoder and a decoder up to 8th order, an encoder with distance correction, an in-phase decoder, opcodes for the two-dimensional equivalent of Ambisonics for any order, opcodes for Ambisonics equivalent panning (AEP) and several utilities such as coordin...
