EVP SHIFTER 3 Sound Banks - 2,000 sounds each (6,000 total). Audio is played in randomized "Bursts". 1 Noise Banks - Contains no speech sounds. Made from the inter frequencies across the AM/FM/SW/VHF/UHF bands. 4 Band Equalizer - Adjust the Low, Mid, Upper, and High ranges of frequencies. Mic Feedback Delay - Automatically turns on the Microphone when audio is played. This creates a Feedback Loop by feeding the audio's output back into itself. YOU MUST RECORD! - The app is designed for Enhanced EVP Communication. Recording your session and then reviewing the audio is critical for receiving messages. The app should sound incoherent, the audio coming through should just be gibberish unless something or someone is using it to communicate. Listening and deciphering messages takes practice, you learn to develop an ear for it over time. If you don't know how to record, look up how to use the built in record feature in IOS. ESTABLISH A CONNECTION - This app may not work for everyone. Establishing a connection to the other side is very important for receiving messages from beyond. An open mind and a focused approach will yield better results. If there's no connection then no messages will come through. Meditation helps. HOW IT WORKS - When you turn on the app it activates the 3 sound banks that automatically adjust their Scan Rate at random and independent of each other. The audio is played in randomized bursts rather than a continuous play. The pitch of the sound is constantly changing. We used a Pitch Shifter effect to periodically create stutters or disturbances in the sound. The Resolution, Frequency, Time, and Amplitude is constantly being shifted. Echo, Phaser, and Chorus audio effects are randomly turned on and off with their intensities randomized as well. We use a combination of the Chorus, Phaser, and Flanger audio effects to implement what is known as Comb Filtering; applying a delayed version of a signal to itself. This creates a variation of a Feed-Back Loop that is known to be an important element for spirit communication. The app also has a "Mic Feedback" feature that turns on the microphone whenever the audio is being played (in a burst). It then turns the mic off when the audio stops playing. This creates a feedback loop by feeding the audio output back into itself. It's important to note that very little communication is heard in "Real time" during the sessions. Though it is possible for this type of communication to take it is not what this app was designed to do. The main focus of this app was to facilitate Enhanced EVP Communication, so recording your sessions and reviewing the audio is essential for using this app. This app is made for audio experimentation by ITC/EVP researchers and is often used by ghost hunters/ paranormal investigators. Results may vary. Note: the IOS version of this app is unable to support mic input and external speaker output at the same time. When mic feedback is turned on, audio will come out of the device’s speakers regardless of connected external speakers. To use with external speakers, please keep mic feedback off. ## Key features - 3 sound banks with 6,000 total sounds - Randomized audio bursts - Noise bank with inter-frequency audio - 4-band equalizer - Microphone feedback delay - Pitch shifter and comb filtering effects ## Recent user reviews (8 of 8) All indexed reviews: https://appshunter.io/ios/app/evp-shifter/id1500826497/reviews.md ### 5/5 — It Works! *2024-06-22* I purchased this app over a year ago when I first began hearing Spirit voices. But I couldn’t get past the sounds. Picked it up again recently and started screen recording each time then playing it back in Audacity. I’ve already recorded many voices! It is important to do the work with Spirit. To make the connection first. And then to develop your ear for EVP. Spirit has been speaking to me when I use many different recording devices (Zoom, Audacity, QuickTime, iPhone). Practice. And listen. They respond when I ask them to say “Hello”, to say their name, and just gave me some personal information. Again, I’ve been recording for well over a year and always hear something. Whether I’m in a mediumship reading with a client, or just me. If Spirit has the time to practice, they will figure it out. Give them and yourself the time to practice.

While this ideology behind an app like this is ongoing experimentation and even this app itself could use some improvements, it’s a 5 star variation on all the other similar devices like PSb7 and version 11. Through digital audio processing we gain access to a virtual version of a guitar amp and stomp effects spirit box Portal in a compact space, and all of his other apps alike. The point of these algorithmic noise makers is to do exactly that, produce the sound waves necessary for your mind to process a synchronicity during a paranormal event. —(this is exactly what the paranormal is, and unless you are in a dream state, it is as close to perceiving the parallel events around us as most ordinary people can get while fully conscious.) The only critique I’d give it is that the feedback loop is very weak through the microphone and I can’t tell if it’s on or off sometimes because it’s not a very loud feedback loop. ### 1/5 — I want a refund *2020-06-29* It would be a good app if you could understand the voices!!!!! I’m so frustrated!!!! I have deadwave Necrophonic and they work fine. Smfh please give me a refund! ### 5/5 — Dave *2020-05-31* Amazing app I do have Necrophonic,but this is just an improvement Had some good spirit responses Even without using my evp recorder Good to use if you are into spirit Communication ### 2/5 — Did not like this *2020-04-05* I would like a refund please I only had this app for less than 10 minutes and don’t like it ### 5/5 — BEST APP HANDS DOWN *2020-03-16* This app is AMAZING! I have gotten so many direct responses from this app that it completely boggles the mind!! NOTE: If you want to record to an external recorder like a Zoom H6, etc. you cannot allow access to the phones microphone. If you have already allowed it find the app in your settings and turn microphone access off. ### 3/5 — Testing it out *2020-03-04* Just bought the EVP shifter , and when I decided to mess around with it and get the feel of the app and how it ran . I noticed the only thing I was upset with is I can’t get it to play through a connected speaker , or wouldn’t play through Bluetooth speaker as well . It would only play through my phone speaker . Maybe it’s a bug that will be fixed ? ## Frequently asked questions about EVP Shifter ### What is EVP Shifter used for?
