Enveloping3D - Algorithms
A. Task
With Higher Order Ambisonics (HOA), an audio technology is available whose original purpose is the representation of spatial audio in high spatial resolution.
In practice, however, as the development work of Saalakustik.de has shown, it additionally requires the possibility of certain, not only geometric, transformations of spatiality.
B. Mode of Action and Areas of Application
The Enveloping3D algorithms developed by Saalakustik.de enable the lossless modification or adjustment of the spatiality of HOA audio material.
Spatiality in the sense meant here is not directly equivalent to reverberation/reverberation time or the strength of diffusivity, instead immersive perception seems to deal with the phenomena described by such parameters in a very specific way, with which in turn the Enveloping3D algorithms correlate excellently.
In addition to their suitability for certain adaptations, e.g. of an aesthetic nature, the algorithms are excellently suited to implement essential aspects and peculiarities of the Enveloping3D methods flexibly and without loss in practice.
