FLUX:: Analyzer Essential

Real Time Analyzer with Peak, RMA and EBU R128/ELOUD Multichannel metering

The foundation of the Pure Analyzer System is the Pure Analyzer Essential, with a comprehensive range of analyzer options for any imaginable audio analysis and measurement, which can be expanded for more specific utilization with up to three add-on modules; Live, Metering/Loudness and Multichannel/Surround.

Product Details

The core of the Pure Analyzer System is a stand-alone software application with full support for standard hardware I/O using ASIO and Core Audio. In addition to this, a plug-in called SampleGrabber, available in all standard plug-in formats, is provided. The SampleGrabber plug-in can be inserted into the insert chain on any DAW or Digital Mixing Console supporting standard plug-ins, where it grabs the source/response audio signal and send it through the network using the ZeroConf/Apple Bonjour protocol to the Pure Analyzer stand-alone app that analyzes the audio in real time.
