'See' EVP and audio spikes as they happen.  
 
The EVP Spike Sensor will help you not miss EVPs.  When you are reviewing you recordings there may be EVPs you are not hearing.   The EVP Spike allows you to make note of an audio spike.   You can then go to that exact time in your recording and listen harder.  Clean up and amplify the clip and there may be an EVP that you would have overlooked

Now you can "see" when audio spikes are happening and thart allows you review them for evidence. This sound sensor utilizes a sensitive on-board microphone to detect audio spikes and translates it to a lighted display. The lighted graph is colored in a range from green to red indicating loudness. It then marks these spikes with an indicator for documenting. It's simple to use, easy to see and lasts a long time.

Displaying sound in colored light
The top side of this investigation tool features a lighted ring of colored light. As sound occurs, the display will light up the ring from one side to the other in a range of colors to indicate loudness. A quiet sound such as a whisper may only light up minimally in green. Louder audio, such as someone yelling or clapping may light up the entire ring in a rainbow of colors from green to orange and red. Green indicates lower sounds while red indicates something considerably louder.
 
Sensitivity control
You can adjust the sensitivity of the microphone to suit your needs. Whether you are in an environment with loud ambient sound already or a steady quiet room, this unit can handle it. On the bottom of the device is a control knob. Just turn it up or down to set it where you're picking up small sounds and you'll be ready to investigate.
 
There's more to this device then just lighting up to indicate loudness. It will also mark when a spike happens and hold it for a bit in case you did not catch it in real time. How do we do this? When a spike of audio is detected, the sound sensor will mark the highest point of the scale and keep that LED light on the ring. It will then hold this light for about 30 seconds so you have a chance to see it and log it. This is helpful in the event you were elsewhere in the room and saw it trigger but didn't quite catch what the high point was. By marking this spike point on the display you have a chance to come over and note the position/color for documentation as potential evidence.
 
A helpful counterpart to any EVP recorder or camera
In short, if the sensor lights up and you didn't hear anything, this may be an indicator of an EVP coming through. On that note, we highly suggest using this in conjuction with an EVP recorder. This audio meter will be super helpful in alerting you to potential captured EVPs.
Better yet, set this meter in front of a video camera with audio. Not only can you potentially capture EVPs coming through the camera itself, but recording video will allow you to see the levels as they happen for cross corellation of evidence.
 
Compact, lightweight and functional design
At just 2 inches in diameter, you can pop this in your pocket. The enclosure, featuring a rugged ribbing for a firm grip, is built with lightweight material for ease of transport. The design is built with function in mind to ensure high visibility and sensivity to audio detection.
 
How does this help with EVP work?
The theory behind EVP (Electronic Voice Phenomena) work is that an entity may have the ability to manipulate the input of an audio recorder - the microphone. That being said, many researchers have found that sometimes a voice may come through the recorder that was not heard in real time. In an effort to investigate that theory, this device was built utilizing the same hardware then translates that to a visual display. It will trigger from both audible sound and, potential, EVP triggers.
In short, utilizing a separate recording device like an EVP recorder or video camera will help differentiate whether the recorded audio was audible to all devices in range or an actual EVP. Working in parallel, this fundamental technique of narrowing down sources of evidence will help determine if the 'spike' was device-specific EVP or an audible sound.
