FINE R+D))™ Viewer
The modern Acoustic Audio Analyzer System


FINE R+D Viewer:
View all measurements / curves from FINE R+D and perform ALL calculations. DRAG responses between FINE R+D Viewer and FINE R+D (incl. ALL Time data). Send out up to 16 responses, TS parameters, distortion and waterfall etc. in ONE document to your customers! 

Price: 500€

The FINE R+D FFT system performs all anechoic acoustic measurements on loudspeaker systems, woofers, midranges, tweeters, compression drivers, headphones, headphone speakers, headsets and micro speakers.


The intuitive FINE R+D system uses the same FINE hardware as FINE QC, providing an R&D system with all advanced features such as up to 16 anechoic FFT measurements, T-S parameters, SPL, and impedance with phase, harmonic distortion, waterfall, real-time analysis (RTA), and numerous curve splice/averaging options.

The latest version even saves the time data so the engineer can change the FTT window and other settings later, giving unseen flexibility. 



You can download a very basic FINE R+D Viewer version. This version can ONLY display what was saved exactly in the FRD file
