Here is an instrument for the measure of sound. With this application you can study the sound through a spectrum in octave-bands. It is composed of different options:

- Harmonic-Random: for random signals like white noise works well but not so well for harmonic signals, detecting multipliers of its frequency.
- Mode: different time averaging can be selected (Slow(1 s), Fast (125 ms), Impulse (35 ms)).
- Resolution: octave-bands or 1/3 octave-bands can be chosen.
- Weighting: Clean, A Weighting, C Weighting.

Hope you enjoy it!
