EVP is the practice of recording audio during a quiet investigation and reviewing it afterward for voices, whispers, or sounds that weren't heard live. It's the most accessible technique in the paranormal hobby — all you need is a recorder — but your results depend heavily on the equipment picking up faint audio cleanly, without introducing its own noise or artifacts. Here's how to choose one, organized by budget.
What Is EVP, Actually?
EVP sessions typically involve asking questions aloud into a quiet room, pausing to leave “response gaps,” and recording continuously. Investigators later review the audio — often slowed down or boosted — for anything that sounds like a voice or word that wasn't audible during the session. Because the entire method hinges on reviewing faint or ambiguous audio, the quality and honesty of your recorder matters more here than in almost any other category of ghost hunting gear.
Dedicated Digital Recorders vs. Smartphone Apps
Dedicated digital voice recorders are purpose-built for exactly this: capturing quiet audio in real-world conditions with minimal self-noise. They typically offer physical gain control, uncompressed or lightly compressed recording formats, and battery life measured in the tens of hours.
Smartphone apps are free and always in your pocket, but most phones run background noise suppression and automatic gain control that you can't fully disable — features designed for phone calls, not evidence-gathering. That processing can smooth over or outright remove the faint, irregular sounds EVP investigators are looking for. Apps are fine for casual, low-stakes sessions; they're a real handicap if you're trying to build a serious evidence library.

What to Look For
- Noise floor: The quieter the recorder's own internal noise, the more you can boost faint audio during review without just amplifying hiss. This is the single biggest quality differentiator between a $25 recorder and a $150 one.
- File format: WAV (uncompressed) preserves more detail than MP3. If your recorder only does MP3, use the highest bitrate setting available — heavy compression can create digital artifacts that get mistaken for EVPs.
- Battery life: Investigations can run for hours. Look for 20+ hours of continuous recording, and carry spare batteries regardless.
- Physical buttons you can operate blind: You'll often be recording in the dark. Tactile, well-spaced buttons matter more than a touchscreen.
- External mic input: Higher-end recorders let you attach a shotgun or lapel mic for more directional or discreet recording — useful once you outgrow the built-in mic.
Entry-Level Tier (–)
Entry-level recorders are simple one-button-record devices, usually MP3-only, with a built-in omnidirectional mic. They're perfectly serviceable for learning the technique and doing your first dozen sessions. Expect a noticeable noise floor when you boost quiet sections, but for the price, they get people into the hobby without a big commitment.

Mid-Range Tier (–0)
This is the sweet spot for most serious hobbyists. Mid-range recorders typically add WAV recording, better mic sensitivity, manual gain control, and meaningfully lower self-noise. Many also add a low-cut filter to reduce handling noise and wind rumble, which matters if you're investigating outdoors or in drafty old buildings.

Prosumer Tier (0–0+)
Prosumer field recorders (the kind used by podcasters and field audio recordists, repurposed by serious investigators) offer multiple mic inputs, adjustable sample rates, XLR/phantom power support for professional shotgun mics, and very low noise floors. This tier is overkill for a beginner but is what dedicated EVP researchers gravitate toward once they've outgrown consumer gear — the ability to pair a directional shotgun mic with a clean preamp makes a real, audible difference when reviewing faint audio.

A Note on Shotgun and Lapel Mics
If you move up to a recorder with an external mic input, a small shotgun mic can dramatically improve directional pickup (useful for pointing at a specific corner of a room), while a lapel mic is useful for close-range, low-noise capture during a one-on-one EVP session.

Frequently Asked Questions
Q1: Can I just use my phone for EVP recording?
You can, and many people start there, but built-in noise suppression on most phones actively works against what EVP investigators are trying to capture. If you're serious about the hobby, a $30–$50 dedicated recorder will outperform a phone app immediately.
Q2: WAV or MP3 — does it really matter?
Yes, more than most beginners expect. MP3 compression discards audio data to save space, and in the process it can introduce artifacts — clicks, warbles, phantom tones — that sound uncannily like EVP but are actually compression noise. WAV avoids this entirely.
Q3: How long should an EVP session recording be?
There's no fixed rule, but most investigators record in 20–30 minute segments per location to keep review manageable. Longer continuous recordings are fine technically — the tradeoff is just how much audio you'll need to sit through afterward.
