Akulap Audio measurement suite
With Akulap you can perform a wide range of measurements for room acoustics and building acoustics.
The system consists of:
 |
Windows Notebook/Tablet PC |
|
Analysis software Akulap |
|
USB measurement microphone |
|
optional sound level calibrator |
By using small notebooks , you can easily build a mobile measurement system. The large color display gives you a quick overview of all relevant parameters.
Akulap is a professional Windows ™ application for powerful real-time signal and system analysis.
By using the PC environment, it is not only a cost efficient replacement for classical laboratory equipment. AkuLap offers more powerful features combined with a comfortable user interface. Typical applications are acoustic measurements, room and building acoustics and noise monitoring.
If you run Akulap on a notebook or even a tablet PC, you can easily build a mobile measurement system.
