Description
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.

It is a great app, I am hit with infrasound pulsed this log it perfectly even when traveling in a car location is everything

Police used your app as evidence so thank you 2019 files geolocation/infrasound to audible works so well that we have 175x3+3 logs in evidence. V2K proven. Hacker blocked aspects of your app even with uninstall/reinstall will try a reset of tablet system.

I'm using this app for years now, documenting the low noise that wakes me up. Solid app, with the right settings you can pick out the exact frequencies in the low rumble. The waterfall plot gives a good overview of how sound evolves over a short time. Love this app, only one for me that genuinely picks up the low rumble I'm sensitive yo.

Doesn't 'analyze' anything. I have a clear humming noise that I can hear, but the app detected nothing. A regular recording app even showed the pattern.

Installed for cat, cat was unimpressed.

This app actually doesn't measure infrasound, it just records all sound in the surroundings but incorrectly (sound doesn't actually oscile whereas vibrations from sound do ;)). How can anybody be so stupid to deduce anything from the results… Buy a standard infrasound meter for frequencies especially near to zero. Nothing else would help.

App stopped registering location and stopped being capable of sending logs. A dozen emails to developer with no replies.
