Hi all, we have completed the first version of a set of VST plugins for an acoustic camera. It can visualise a sound-scene and overlay the visualisation on a spherical video. For the visualisation there are few options, all the them using directly spherical harmonic signals up to 4th order: - a non-adaptive scanning beamformer - an adaptive scanning beamformer (MVDR) - the MUSIC pseudospectrum using the DPD test: "Localization of Multiple Speakers under High Reverberation using a Spherical Microphone Array and the Direct-Path Dominance Test" by Nadiri and Rafaely - a scanning post filter based on the Cross-pattern coherence (CroPaC) algorithm. We found out that the CroPaC algorithm works quite well in highly reverberant spaces ( http://research.spa.aalto.fi/projects/cropac/soundExamples/)
Additional VST plugins are provided for converting either Eigenmike or a-format signals to spherical harmonic signals in real-time. Alternatively, you can just use the acoustic camera plugin directly with spherical harmonic signals as an input or a microphone array and your preferred encoder. You can find the plugins in the following webpage. They have been tested in Reaper for both mac os and windows. In our setup we have used the RICOH Theta S camera and the Eigenmike. http://research.spa.aalto.fi/publications/papers/acousticCamera/ all the best, Symeon Delikaris-Manias -------------- next part -------------- An HTML attachment was scrubbed...
