Pure Analyzer System – The Next Generation RTA (Real Time Analyzer) System


The Flux:: Pure Analyzer System is a modular RTA-system providing a comprehensive range of analyzer options for any imaginable audio analysis and measurement applications, from being an invaluable help to improve your mixes, to critical tasks for professional mastering, broadcast, post-production and live engineers.


The foundation of the Pure Analyzer System is a standalone application, Pure Analyzer Essential, which can be expanded with up to three modules all providing specific tools for their actual field of usage; Live, Metering/Loudness and Multichannel/Surround analysis. In order to use any of the add-on modules, Pure Analyzer Essential is required.


Available add-on modules are:


Audio I/O and the SampleGrabber Plug-in


The Pure Analyzer has full support for standard hardware I/O with 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.


You can insert as many instances of SampleGrabber plug-ins as you need, on the same DAW, different DAWs, and even on different computers, and all of them can connect to the same Pure Analyzer app as long as they they’re all connected to the same network.


The Pure Analyzer app displays a Source list of SampleGrabber instances found on the network as well as the hardware I/O configuration, and with a simple click in the Source list one of the audio sources can be selected as the input source for the analysis.


Network Requirements


The network configuration setup for the Pure Analyzer System is entirely automatic and transparent to the user. The audio transport requires approximately 1.4Mbps for each channel at a sample rate of 44.1kHz, so a properly configured standard Ethernet 100Mbps network should be more than sufficient to handle most cases.


The SampleGrabber plug-in supports multichannel configurations for using with the Multichannel add-on option, and a multichannel 5.1 configuration in 96kHz demands slightly less than 20Mbps.


Obviously these requirements do not apply when using both SampleGrabber and Pure Analyzer on the same hardware.




The Pure Analyzer System is available for Mac OS X, Windows, AVID Venue, with support for up to 16 channels (in Multichannel/Surround configurations and Multi Microphone System Analysis) at up to 384 KHz.


The graphic analysis rendering in Pure Analyzer is using a GPU-efficient 2D/3D graphic engine, based on the OpenGL 2.0 standard, optimizing the audio-to-visual experience utilizing the GPU on the built in graphics card.

Basic Requirement (Mandatory!)


The Pure Analyzer Essential is required in order to run any of the add-on modules; Pure Analyzer Metering, Pure Analyzer Live or Pure Analyzer Multichannel. The add-on options are not compatible with the Studio Session Analyzer (included in the Studio Session Pack bundle).

System requirements


Pure Analyzer is built around Flux::'s new 2D/3D efficient graphic engine, which employs full GPU-acceleration utilizing an OpenGL 2.0 compliant graphics card.


In order to experience the outstanding graphical response in Pure Analyzer and to fully take advantage of the software's analysis capabilities, using a modern nVidia or ATI Radeon graphics card is recommended.
Older, and other less efficient graphics cards do not have the required performance and specifications, and will offload too much work to the CPU.


The processor is an important factor as well, and we recommend using at least and Intel Core 2 Duo, Core i5 or newer architecture processor. AMD processors are also supported, but might exhibit lower performance, as they do not offer the same capabilities and optimizations as Intel CPUs.


System recommendations


GPU: AMD/ATI Radeon or nVidia video-card. Intel integrated graphics are tested and works, but with limited capabilites, thus should be avoided.


Minimum requirements

  • CPU: Intel Core 2 Duo @ 1.6 GHz
  • GPU: OpenGL 2.0 or superior compatible, with pixel-shader support


Recommended configuration

  • CPU: Intel Core i5 @ 1.7 - 2.2 GHz or better
  • GPU: AMD/ATI Radeon or nVidia. Intel integrated graphic-cards are tested and works, but with limited capabilites.


Common requirements

  • An iLok account (no iLok USB key required), or a Flux:: dongle and a free USB port to connect the dongle.


Please make sure that the latest version of vendor-provided optimized drivers are installed for your graphics card. Generic drivers may contain bugs and are in general less up-to-date with optimizations presented in drivers specific to your particular graphics card model.


Compatibility, Pure Analyzer Application


Operating Systems

  • Windows - 7 SP1, 8, 8,1 and 10 all in both 32 and 64 bits.
  • Mac OS X (Intel) - 10.7.5, 10.8.5, 10.9.5, 10.10.5 and 10.11.5 in 64 bits.


Hardware I/O support

  • Core Audio (Mac OS X)


Installed Application Files


  • Windows 32 bit
    • FluxTAnalyzer-x86.exe
    • FluxTAnalyzer-f64-x86.exe


  • Windows 64 bit

    • FFluxTAnalyzer-f64-x64.exe


  • Mac OS X 64 bit
    • FluxTAnalyzer
    • FluxTAnalyzer-f64


The f64 Pure Analyzer application works internally in 64bit float, while the non f64 version works internally in 32bit float, it’s a minor difference in precision, with the 64bit version consuming more processing resources.


The 32bit version is already very precise, and more than enough for all common everyday applications. The 64bit version is provided for very specific applications; that sometimes may require extreme detail in the analysis.
