The software was designed to be applied during lectures, when live measurements have to be performed quickly without having to access submenues. All parameters are visible and can be changed in the GUI.
Following functions are just a selection of what can be done with this tool. For more information read the manual.
-Simultaneous recording of 4 channels: voltage, sound or acceleration signals
-Supported hardware: windows sound cards, National Instruments devices (see manual)
-Calculation of sound pressure, particle velocity, rms value, SPL
-Generation of sine or sawtooth signals, signal with several partials, white noise, chirp, gaussian pulses, rectangular pulses
-Continuous or single DAQ
-FFT analysis, third octave, octave band analysis
-Frequency response
-Spectrogram
-Insertion or transmission loss
-Different types of averaging
-Save results to Excel or MATLAB files
-Import and compare MATLAB or wav files
