Great free app! Helps me collect proof of ongoing infrasound exposure. Questions re: Event Log entries spanning more than 24 hrs show only the amt of time in the current calendar day; and don't know how Event Log deals with simultaneous multiple frequencies in the signal. Being able to monitor infrasound in my home is extremely important & valuable. Grateful for this app!

Best app of its kind (free OR paid!)!! Actually, irrespective of purpose, it's best app PERIOD!! I'm a developer & this level of quality w/ no ads or upsells is unprecedented! UR helping so many people! A quality, easy to use tool that newbies can use right "out of the box" & offers all the customization imaginable for advanced users!!! The ability to record, log and share activity, graphs (html) and spreadsheet (csv)....too much good! Sergio is angel to TI community! Thank you! God bless!!

I am stunned by the way this app actually does what it says it can do! I'm so used to misleading apps that do not deliver then read it is in the entertainment category! This is a model for every person who is thinking of creating an app? Stick to this as a point of reference and guidance when finding yourself slipping into the realms of lying, cheating click bait application creation! Fantastic work to the team of developers that created this, or the one creator? I think it was a team effort though. (stunned to find out it was done by one creator, your talented. Excellent buddy.

Totally love it. It seems unbelievable but it works exactly as it is shown and even better. This is the first app I'm reviewing because this app is outstanding!

Started off recording hours of infrasound .And now only records for a few minutes at a time .All ok now just had to reboot android phone. However i am still cautious as to if these results will prove to be a valid reason with my ongoing complaint with council regards to low frequency humming sound. Anyone used this app for the reason i describe?

I put my phone next to a known infrasound source of ≈10hz. I could feel my eardrums popping in and out. Various parts of my body were jiggling uncomfortably yet I couldn't hear the sound. The app registered zero. Edit: when I enabled my accelerometer it easily detected the 10 Hz signal. Since the app does, in fact, detect the infrasound, it gets another star. My mic could have a band pass filter that attenuates infrasound before it gets to the app. Alternately, the mic may be sensitive to and saturated by the carrier that generated the infrasound and effectively deafened to the point of not registering the sound. In light of these possibilities I can't give this app a negative review even though it didn't happen to work in my particular circumstance. Infrasound was parametrically demodulated via a complex carrier that has an acoustic DC bias but not an electro-mechanical DC bias. DSBSC-AM modulating this carrier yields a demodulation product -3 dB of the carrier.

About this app

InfraSound Detector is the App that allows you to detect infrasound (infrasonic) acoustic signals below the user-defined frequency (up to 30 Hz by default).

Infrasound propagates hundreds of miles and can penetrate walls, mountains and other obstacles without loss.
This detector can be useful in following cases:

To find out any suspicious low frequency noise, vibrations, and sounds in building structures.
To register a number of hazardous atmospheric phenomena, including aircraft wake vortices, clear air turbulence, severe thunderstorms and tornadoes as well as any seismic events and volcano activities. As a benefit, it allows early detection of tornadoes from hundreds of miles away.
To detect underground activity, e.g., tunnel digging.
To detect some kind of infrasonic weapons, that cause physical pain without human detection.
To check out the quality of bass sounds (low frequency) of your subwoofer speaker system as well as any loudspeakers.

Result of detection can be shown on the screen in the foreground mode and also be presented in the notification form and (or) by sound (vibration) in the background mode when the screen of the Android device is turned off. All events can be recorded in the log for later analysis. The lower working frequency is depend on the audio specification of the current Android device and can be reached as low as 4 Hz. For better result, the high quality Android device with internal microphone should be used to determine the infrasound signal, but sensitivity on the lowest frequencies will be worse anyway. Also, you can use a special external infrasound microphone connected to the audio jack (microphone input of the ear plug connector).

The idea of the App is based on the fact that any analog system (microphone and amplifier of your Android device in this case) does NOT have ideal characteristics and infrasound signals can be infiltrate through it down to 4 Hz.

Features.

Completely NO ads.
The signal level indication.
Vibration indication of the alarm event.
Event log is recorded automatically. Signal spectrum and location information can be included in the log.
The converter infrasonic signals into audible sounds. So you can hear infrasonic signals.
Background mode with notifications. Once this option starts, the App runs quietly in the background and requires no human interaction until the alarm event happens. It continues to run even after the device reboots.
Adjustable battery consumption in the background mode. The App is designed to conserve your device battery and allows to select the data update rate. The more update rate time, the less battery it takes.
Comprehensive spectrum analysis with different ways to display results: spectrum, waterfall, oscilloscope.
Adjustable frequency range and selectable frequency resolution between 0.1 and 1 Hz.
