WINAIR :
Select MLS as analysis signal, and once you have the measure ready, one or an average of, go to
"Storage" and "save as", put a name and it will be saved a *.txt file. The format should look like this:
WinAIR saved file

CALSOD / DAAS 32:
To use measurements from DAAS 32 we need to export the Calsod files, they normally are *.spl extension
files for DAAS 32 . The file will contain Freq response, magnitude and phase data. The format will be like this:
CALSOD
Frequency resp. NoName 0000 ,

21.27 39.30 53.50
Acoustilyzer:
We are able to import measurements of FFT data from Acoustilizer. Also with a 1/3 octave smoothing in
SPL. We have to import the *.txt file, that will have frequency response, magnitude but no phase information.
The file will look like this.
FFT Measure SPL 1/3 Octave
