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


We want you to try the FINE R+D Viewer:
Send out up to 16 responses, TS parameters, distortion and waterfall etc. in ONE document to your customers! Or receive 16 curves from engineers and partners. Of course we hope you will then buy the real FINE R+D measuring system.

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. THIS is also possible in the Viewer!
