| dc.description.abstract | With the increase of the computational power of DSP's and CPU's, impulse responses (IR) and the convolution process are becoming a very popular approach to recreate some audio effects like reverb. But although many IR repositories exist, most IR consider only mono or stereo. This paper presents an approach for impulse response upmixing using particle systems. Using a reverse engineering process, a particle system is created, capable of reproducing the original impulse response. By re-rendering the obtained particle system with virtual microphones, an upmixing result can be obtained. Depending on the type of virtual microphone, several different output formats can be supported, ranging from stereo to surround, and including binaural support, Ambisonics or even custom speaker scenarios (VBAP). | eng |
