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
-Insertion or transmission loss
-Different types of averaging
-Save results to Excel or MATLAB files
-Import and compare MATLAB or wav files

New section definition and cut functions were added. Smaller bug fixes were done.
New function was added: spectral centroidal frequency
A bug in the partial detection function was fixed.
Graphical toolbar was added in the analysis window
"Attack" analysis function was added, e.g. now time transients of partials can be plotted and exported
Following changes were made:
The number of selectable audio input channels was increased to 5 (instead of 3).
The version number was changed to 2019.08.0.
