ProAudio Tools

Simple sound level meter and real time analyzer

ProAudio Tools Release 3.1 includes:

1. Sound level meter with the following options:

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

* Upside Down Mode

* Calibration option

* Reference of common sound pressure levels of applications.

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

2. Real Time Analyzer:

* Capture frequencies up to 8000 Hz

* Hold capture

WARNING: The smart phone has a limited audio response. Also there is a 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)
