ProAudio Tools is the first version of a basic app for people enthusiastic about audio.

This implementation includes a decibel meter that can give an approximate idea of the current sound pressure level where you are located.

The current version includes these options:

1)	Different time acquisition; Slow (1 s), Fast (125 ms), Impulse (75 ms)

2)	Upside Down Mode 

3)	Calibration option

4)	Reference of common sound pressure levels of applications.

5)     Represented minimum, maximum and average dB value (press at the blinking "Capturing Audio" to restart the levels)

WARNING: The smart phone has a limited audio response between (300 - 3400 Hz). Otherwise there is only 16 bit resolution so it´s only possible to reach a maximum of 32767 levels instead of the real level range (0.0002 to 200 Pa) of the difference sound pressure, that give us a total a range of 90 dB (not 120 dB)
