XL2 acoustic pressure-time history logging

 Hi, I recently purchased the XL2 and I was hoping I can simply record acoustic pressure time history, store it and then analyze this data in PC using Matlab/whatever..


Reading the manual I am now not sure whether this is actually possible or if I need to purchase some software extension?


What I need is to simply record few seconds of measured noise and store this data - ideally in pascals already.


Anyone can help?

Thanks

Martin


Hello Martin,


you can log measurement results on the XL2 SD memory card and copy those results to your PC after the measurements for further analysis. For this, you don't need any additional option.


If you need to query live values from the XL2 via USB interface, then you would need this option:

Hello Martin,


What resolution do you want the data, 48k times a second or an average every second?


For high sampling, setup the XL2 to Log and additionally log audio.

 Gregor, Brian,


thank you both very much. I was busy with other projects lately so I didn't have a chance to try it yet, but I will soon.


BTW 48k sampling frequency is perfect for me. And thanks for the link on scaling WAV files!


Have a happy new year!


Martin
