FINE R+D: Loudspeaker research and development software
FINE R+D provides advanced acoustic analysis and research tools for loudspeaker engineers and OEM development teams. The software enables detailed measurement, driver analysis, and acoustic system optimisation. It delivers the advanced functionality needed to analyze modern audio systems with confidence and speed – without requiring anechoic chambers.
Key features of our loudspeaker research and development software:
High Sampling Rates
Supports 48 kHz, 96 kHz, and 192 kHz for detailed, high-resolution audio measurement.
Real-World Room Testing
Measures SPL and impedance up to ~100 kHz in normal rooms, no need for expensive anechoic environments.
Direct Measurement of Audio Devices
Analyze speakers, smart speakers, microphones, amplifiers, and crossovers directly, all within one system.
Precision Impedance Testing
Perform high-accuracy impedance measurements with selectable LO (Low current) and HI (High current) modes.
Flexible Time-Domain Analysis
Saves all time data, allowing engineers to modify the FFT window and other parameters later, ideal for post-measurement refinement and analysis.
Advanced Visualization Tools
Includes automatic polar plots, contour plots, and conversion from measured frequency responses.
Normalization Mode
Ideal for showing the difference between (off-axis) curves or comparing relative SPL levels with high precision.
Multi-Microphone Array Capability
Capture SPL data from up to three microphones simultaneously with one click. Supports GRAS, (30 kHz or 100 kHz), PCB and all microphones with Phantom 48V, ideal for spatial and off-axis analysis.
Designed specifically for Loudspeaker and Acoustic Professionals
Unlike generic analyzers, the FINE R+D is specifically designed by loudspeaker engineers for real-world speaker and system development. Its intuitive interface, flexible post-processing, and real-time accuracy allow you to make critical design decisions faster, without costly guesswork or rework.
Get trusted, lab-quality data in normal environments, and get to market faster.
Trusted by leading sound companies worldwide
The FINE R+D loudspeaker research and development software is used by DeVore Fidelity, Wet Sounds, Sonodyne and Audio Technology to help them with their sound project, to name but a few specialised sound companies.

Loudspeaker Reseacrh and Development – Frequently Asked Questions
What is Loudspeaker Research and Development Software?
The Research and Development Softwarer is specialized software and hardware system used to measure and analyze the acoustic performance of loudspeakers, microphones, and audio components. It captures data such as SPL (Sound Pressure Level), impedance, and frequency response to help engineers refine audio designs.
Does the FINE R+D software require an anechoic chamber?
No. One of the key advantages of the FINE R+D Acoustic Audio Analyzer is that it performs highly accurate measurements in normal rooms, eliminating the need for costly and complex anechoic environments.
What sampling rates are supported by the analyzer?
FINE R+D supports 48 kHz, 96 kHz, and 192 kHz sampling rates, offering flexible resolution levels depending on your measurement requirements.
Can I use the analyzer for multi-microphone testing?
Yes. The Multi-Microphone Array module enables simultaneous SPL measurements from up to three microphones, ideal for spatial or off-axis response analysis. GRAS microphones (30 kHz or 100 kHz) and generic microphones with phantom (48V) are supported.
Is post-measurement analysis possible?
Yes. FINE R+D saves all time-domain data, allowing engineers to modify FFT windows and other parameters after recording. This provides greater flexibility for in-depth analysis and decision-making.
What types of devices can be tested using this system?
The Acoustic Audio Analyzer can measure speakers, smart speakers, amplifiers, microphones, and crossovers directly—providing a complete solution for speaker design and system integration.
How accurate is the impedance measurement?
Impedance can be measured with high accuracy using two selectable modes: LO (Low current) and HI (High current), allowing precise characterization across different component types.
Is the system easy to use for non-specialists?
Yes. The analyzer is designed by loudspeaker engineers for real-world use, with an intuitive interface that requires no formal training. Engineers can start testing and optimizing immediately.
Can I generate polar and contour plots automatically?
Yes. The system includes built-in functionality for creating polar plots, contour plots, and frequency response visualizations, making it easier to communicate and document results.
