System for Online Localization of Sound Sources in Real Time
HEAD VISOR is an innovation from HEAD acoustics GmbH in the area of microphone array technology that suits localization, visualization, quantification an auralization of sound sources. By means of its unlimited online processing.
HEAD VISOR literally allows you to expand your senses and to handle acoustic tasks in a completely new way. Immediately after turning the system on, yoy will see a video image with a synchronously superimposed high-resolution map of the sound sources. The influence of modifications, analysis settings, etc. can be monitored directly. You don't even have to start a recording. Thanks to the FreezeBuffer, sound events can be conveniently captured and analyzed even retroactively.
Together, the hardware and software compo- nents of HEAD VISOR constitute a perfectly match system that provides all required parts. Simply set up the hardware components, turn them on and immediately HEAD VISOR delivers live video images with a synchronous, superimposed, high-resolution map of sound sources.
Source mappings, analysis results and audio signals are calculated and displayed in real time - continuously and not time-limited. All analysis settings and modifications to the sound sources are immediately reflected by the results you get.
HEAD VISOR delivers all results online, i.e. source maps, analysis results, audio signals, auralizations etc. Are available immediately. The influence of modifications, filtering or changes to the sound sources can be viewed instantaneously.
HEAD VISOR calculates the coherence of the array microphones with a reference sensors (microphone, accelerometer etc. online and removes or amplifies the corresponding sound components.
At several user-defined positions in the image, the emitted sound signal can be calculated, auralized and exported for further analysis, e.g. with ArtemiS.
HEAD VISOR continuously buffers e.g. the last 25 seconds - regardless of whether a recording is just being made. The multi-step slow motion function (down to freezing a single frame) always keeps source mapping, video image, analysis and auralized audio signals synchronized (without affecting the pitch).
Detection of distances to sources located behind each other using three industrial-grade cameras.
For the online monitoring of RPM-dependent changes, an RPM signal can be fed into the data stream For each order, HEAD VISOR delivers a separate source map.
Source mappings can be exported as AVI videos (with sound) or still stand images (JPG, BMP, PNG) and audio signals can be exported as WAV or HDF files.
