The Complete Live Analyzer Solution

Pure Analyzer Live is not a full product, in order to run this, the Pure Analyzer Essential is required!

The principle of the Pure Analyzer System is to provide the option to capture the source signal with an entry-level laptop, or a digital live console with support for VST/AU/RTAS/TDM plug-ins, using the Sample grabber plug-in (see more under "Pure Analyzer Essential").

The actual analysis is then performed using a computer with a graphic card supporting OpenGL/DirectX. The system could also be coupled with a wireless transmitter to route a source test signal to the laptop to perform transfer curve measurements at different locations more conveniently.

The Pure Analyzer Live provides the elements needed to assist the live sound engineer in speaker array calibration tasks: a delay finder, level, meter, transfer function magnitude, phase and coherence spectra, and impulse response, as well as snapshot facilities.

Add-on Modules

As a complement to the Pure Analyzer Essential, in addition to the Pure Analyzer Live module, two other different add-on modules providing specific tools for their actual field of usage, are currently available. In order to use any of the add-on modules, the Pure Analyzer Essential is required.

Other available add-on modules are:

  • Pure Analyzer Metering.
