Did you know ...

... the XL2 Sound Level Meter can record audio during FFT and 1/12 octave measurements?

Load the files “fftaudio.txt” and “12audio.txt” (available below) into the root directory of the XL2. This enables 24 bit, 48 kHz resolution audio recording while using the FFT and 1/12 octave measurement functions. The XL2 should have firmware V4.10 or higher and the “Extended Acoustic Pack” Option installed.

Open "fftaudio.txt" and “12audio.txt” and save as respective txt files.

Is it possible to see a sonic boom?

No ... and yes: if an aircraft flies faster than the speed of sound and the humidity of air is high enough, the change of air pressure causes condensation and forms a conical cloud. This change of air density also causes a change in the refraction index.

See this amazing effect in this video!
