【實用工具app】APM Tool Lite|最夯免費app-綠色工廠好玩App

This application allows you to rapidly measure Reverberation Time (T20 and T30) and Definition (D50) in octave bands using your Android Device.

The software has been developed starting from a collaboration between Suonoevita and the Politecnico di Milano Master Degree for a Thesis work: it follows ISO 3382 and IEC 61672 specifications and has automatic gain control as well as clip-detection algorithms that makes it unique.

It has been proved on field that is able to give really good estimates starting from the 500Hz octave frequency band: unfortunately your phone is not a Class I precision instrument!

In the Lite version you can obtain the Acoustical Parameter results in octave bands by averaging a maximum of three handclaps: wait for the device to give you an audio/visual feedback and you're ready to go! You can save the measurement session and/or export results on a .csv file for your personal needs.

Check out all the features of the full version in the INFO tab of the application or by visiting https://play.google.com/store/apps/details?id=it.suonoevita.apmtool&hl=en
