APM Sweep app for iPhone and iPad

APM Sweep is the successor of the well known APM Tool: it let you quickly measure the acoustical performance of a room (reverberation time, clarity, etc. in octave and third octave bands), check if that room is well suited for its purpose and, if not, choose which materials can improve the acoustical quality. Everything still there but with an exciting improvement: now you can use all the power of the Exponential Sine Sweep technique for the measurement process, so your results can be extremely precise and accurate.
You can also, save, load and export results in common spreadsheet format.
The app can also generate pdf reports with photos.
A tutorial slideshow explains the app use.
Required at least iOS 11.0
