This app does audio amplification of low audible signal and noise cancellation in real-time. The app allows the operator to design custom ideal filters such as Lowpass, Highpass, Bandpass and Bandstop filter by drawing on the touch screen. You must plugged a headset( or headphone) into the device headset jack. This is a requirement in order for the app to work. The app also amplify your surrounding environment and act as a hearing aid as well.
Three Noise Filter Modes:
- Removed the frequency with the highest decibel level.
- Preset the voice range from 300 hz to 3.5kHz
* Will add more preset range in future release.
- Remove frequency range using bandpass filter.
-Can remove certain frequencies using the drawing method on the graph.
* Note: when this mode is selected, draw the frequency using the touch screen method.
☆ Three noise filter methods to choose from
☆ Act as a hearing aid by increasing the volume gain level.
☆ Has a FFT spectral analyzer graph for displaying frequency.
☆ Select-able microphone input.
☆ Automatic gain control

Noise Sound Light level meter
dB Lux counter
REMEMBER!! The built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB)...
SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. We had calibrated many android devices with the actual sound level meter with dB(A).
See the 4-6th pictures. I had calibrated many android devices with an actual sound level meter. You can trust the result in routine-noise levels (40-70dB). But, please use it as an auxiliary tool.
* Pro version added Features :
- Sound Meter and Vibrometer are integrated
- Statistic menu with saving log data

Noise hurts and makes sick. The major reason is that it causes the human body to discharge stress hormones that increase blood pressure and accelerate your heartbeat. Noise is dangerous and there is no immunity against it.
The Noise O Meter application is for making you aware of the quantity of noise you are exposed to every day. The application is able to recognize noise caused by sound pressure and by high frequencies. It should help you understand the problem and warn you when you are in danger of reduced quality of life through noise.

Use your phone as a surveillance camera with this new app. Watch what is going on in other rooms of your house or in other areas of your office.
Your phone, in combination with your wireless network, can be used to monitor anything that is going on in your house.
See what your kids are up to. See who is coming to your door while sitting at your computer. Keep an eye on the sleeping toddler.
Just follow these easy to use instructions:
Step 1: Open Eye Spy and activate the Eye Spy camera by clicking the center sphere.
Step 2: You will be given a web address, type it into the browser on your computer or second device.
Step 3: You will see a picture taken from your front or rear camera.
Step 4: Hide the phone.
Step 5: In your browser, select the refresh frequency of the spy camera.
Step 6: Watch.
Eye Spy will only work on your own wireless network. No one outside your home or work network will be able to see what you are looking at.
If you have an older phone or a tablet, you can set up Eye Spy on that device and watch what is going on with your newer phone. Otherwise, you can watch what is going on from your computer.
You can use Eye Spy by itself, or you can use Eye Spy along with Ear Spy and a bluetooth headset to watch and listen to what is going on in another room.
If you are going to use Eye Spy for a long period of time, it's a good idea to plug it in because it will be using battery power as it runs.
24 Hour Refund Period
This app is very new. We've tested on a lot of devices and it works on all of the ones we tested. However, just in case you do have problems, we are going to extend the normal 15 minute Google Play refund period to 24 hours. If you send us your Google Play email receipt within 24 hours of purchase, we will refund your money if you are not happy. Send to email@example.com and ask for an Eye Spy Refund.
Have fun, and please use Eye Spy responsibly.
Check out our other Spy apps: "Ear Spy" which will amplify your hearing to hear what is going on around you, and "Alarm Spy" which will turn your phone into a motion detector alarm.
This is a "spy" application, but we do not spy on you.
We do not collect or store any information about the users of this application. Once you download it, it runs on your phone and never communicates with our servers. Our business is building software--not selling information.
