This application allows you to rapidly measure Reverberation Time (T20 and T30) and Definition (D50) in octave bands using your Android Device.
Now it allows you to test the direct method of creating an acoustic impulse (clap or baloon pop) and the sinesweep method which is reliable even with BT sources.
It is able to give really good estimates starting from the 500Hz octave frequency band upwards.
In the Lite version you can obtain the Acoustical Parameter results in octave bands by averaging a maximum of three handclaps/sinesweep: 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 full features of the APM Sweep version in the INFO tab of the application or by visiting https://play.google.com/store/apps/details?id=it.suonoevita.apmsweep&hl=en
Note Remember to have the microphone use active for this application (check in the app permission preferences) otherwise it won't work
Note On many smartphones if you use the clap method you'll need to adjust the AGC and sensitivity options
