APM Tool Lite

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.
