The simplest correct approach: run a spirit box or spirit-box app alongside a separate, dedicated recorder set to a high-quality format, keep the room free of interfering electronics, start with a sweep rate around 100 to 150 milliseconds, and let the whole session record continuously. Review the audio afterward instead of judging responses in real time. That single habit, recording first and reviewing later, cuts down on hearing what you want to hear and gives you something you can actually verify.
TL;DR:
- Using a separate digital recorder in WAV format improves audio clarity and preserves spectral detail compared to phone mics, especially for analysis.
- Starting with sweep rates around 100 to 150 milliseconds and recording both AM and FM bands helps identify the clearest signals specific to your environment.
- Keeping electronics powered down or in airplane mode reduces interference, making background noise easier to distinguish from potential responses.
- Listening to recordings without bias, verifying responses against questions, and maintaining detailed logs enhance the credibility of spirit box sessions.
- Proper setup, including labeling batteries and files and recording continuously, prevents data loss and ensures more reliable review results.

What You Need: Gear and App Options for Capturing Clean Spirit-Box Audio
Every solid spirit box session starts with the right combination of tools, not just a spirit box. Here’s the core kit worth assembling before you head into the field.
- A spirit box or spirit-box app — a physical unit or a mobile app that sweeps AM/FM frequencies to generate the raw fragmented audio you’re analyzing.
- A standalone digital recorder (like a Zoom H1) or a phone running a dedicated recording app, kept separate from the spirit box itself.
- An external speaker or headphones for real-time monitoring without relying on a tiny built-in speaker.
- Cables or adapters if you’re running a line-in connection instead of relying on ambient mic pickup.
- Spare batteries for both the spirit box and the recorder. Dead batteries mid-session are the most avoidable failure in this hobby.
- A stable surface or small tripod to keep the setup from shifting and adding scrape noise to your track.
A dedicated recorder earns its place because of format flexibility and dynamic range. It captures uncompressed WAV files and handles quiet-to-loud swings better than most phone microphones. Spirit-box apps have real advantages too: some highlight suspected response moments directly in the recording waveform, which speeds up review for beginners who don’t yet know what to listen for. The tradeoff is fidelity. Phone mics compress dynamic range, and a phone’s own radio hardware can occasionally bleed interference into a session. Practitioner guides generally recommend pairing a spirit box with a separate recorder rather than relying on one device to do both jobs.
How to Set Up and Run a Spirit Box Session Step by Step
Getting good spirit box audio recording results comes down to preparation as much as the session itself. Rushed setups produce muddy files and missed windows.
Before you start:
- Charge everything, and label your batteries and memory cards by date if you’re running multiple sessions in a week.
- Do a 30-second test recording to confirm levels are clean and nothing is clipping.
- Pick a quiet location and note the environmental baseline. HVAC hum, traffic, pipes. Write it down before you start.
- Set your spirit box where its speaker can sweep openly, without being muffled by furniture or your own body.
- Place the recorder close enough to capture clean audio, using a line-in cable if your setup supports it, but not sitting directly on top of the spirit box speaker where it will overload the input.
Running the session:
- Announce the start out loud. State the time, location, and device names for your own log and for anyone reviewing later.
- Ask short, direct questions and pause 5 to 10 seconds after each one before asking the next.
- Keep a running log, written or spoken into a second channel, of timestamps tied to each question.
- Record continuously. Don’t stop and restart between questions. A single unbroken file is far easier to review than a folder of clipped fragments.
Pro Tip: Monitor your levels through headphones during the session, not just the speaker. You’ll catch clipping and wind noise in real time instead of discovering a ruined file the next morning.
Keep a second recorder running in an adjacent empty room whenever you can. That control file becomes your baseline for what “nothing happening” sounds like in that exact space.
Recording Settings, Formats, and Sweep-Rate Guidance
Format matters more than most beginners expect. Record in uncompressed WAV at 44.1 to 48 kHz and 16 to 24 bit, or another lossless format your recorder supports. Skip low-bitrate MP3 for anything you intend to analyze closely. MP3 compression discards frequency data your ears might not notice on playback but that a spectral analysis tool absolutely will.
Set your gain so the loudest moments in the room don’t clip, while quieter potential EVPs still register above the noise floor. A short test clip before every session tells you whether your levels are dialed in or need adjusting.
Sweep Rate Starting Point: Experienced investigators generally start sweep rates around 100 to 150 milliseconds, then adjust from there. Faster sweeps produce shorter, more fragmented snippets. Slower sweeps sometimes yield clearer syllables, but at the cost of longer, noisier stretches of static.
Log whatever sweep rate you land on for each session. Comparing results across nights without a record of your settings makes it nearly impossible to tell whether a change in your findings came from the environment or from your own tinkering.
Band choice is worth testing rather than assuming. Many investigators lean toward AM because it tends to surface talk-radio fragments more often than music-heavy FM signals, but local station density varies enormously by area. Test both AM and FM in your specific location and note which produces cleaner results before committing to one band long term.
Reducing Interference and Verifying What You Recorded
Ruling out mundane explanations is half the work of a credible spirit box session. Power down unrelated electronics near your setup, put phones in airplane mode or move them to another room, and if you’re testing for radio bleed specifically, a Faraday pouch around a phone makes a useful control.
- Run a control recording in the same environment, same gear, same placement, minus the human questions, so you know what background noise and static normally sound like.
- Import your files into a DAW or an app with waveform highlighting and listen without priming yourself on what you expect to hear.
- Try slowed playback or spectral analysis on ambiguous clips, and use light noise reduction rather than heavy filtering that can distort or invent speech-like artifacts.
| Verification question | What to check |
|---|---|
| Does it answer the question asked? | Timing should be reasonable, not stretched to fit |
| Is it audible without prompting? | A fresh listener should hear it unaided |
| Does it repeat across sessions? | One-off clips carry less weight than patterns |
| Is it logged with a timestamp? | Context matters for later cross-checking |
Field-Proven Tips for Spirit Box Recording
If you’re just starting out, keep it simple: a spirit box or app, a phone or a Zoom H1 recorder, always a control recording, and a notebook or notes app for session details. That combination covers almost every scenario a beginner runs into.
A few habits separate a useful session from a frustrating one. Set your sweep rate conservatively at first rather than chasing the fastest setting out of the gate. Monitor through headphones instead of trusting your ears across a room. Back up raw WAV files the same night you record them, before a phone update or a full memory card wipes something you wanted. And always listen through a full session before deciding anything meaningful happened in it.
What Investigators Commonly Get Wrong
The biggest mistake I see is treating a live session as the verdict instead of the raw material. Talking over the box, reacting out loud to what you think you heard, and skipping a control recording all stack the deck against a fair review. Log everything, label your files the same night, back them up twice, and let the recording do the talking once you’re calm enough to listen without bias.

Gear and Reading That Support This Workflow
If you want to put this workflow into practice without piecing together gear from five different retailers, curated gear collections can help. Unlike generic listings that just push whatever pays the highest commission, well-chosen picks provide honest, plain-language rundowns of what equipment actually does and where it falls short, so you buy gear that matches how you actually investigate rather than a spec sheet.
Start with the spirit boxes, recorders, and kits that make up the core of any session, including the range of Digital Recorders built to pair with a spirit box the way this guide recommends. Investigators looking to add a secondary detection layer often pair a session with the Ghost Detector TEP Pod for a second data point alongside audio. For background reading between sessions, True Haunts: Real Paranormal Encounters and the National Geographic Guide to the World’s Supernatural Places both offer useful location context for planning your next investigation.

FAQ
Are Voice Spirit Boxes Real?
A spirit box is a real, physical device that rapidly sweeps AM or FM radio frequencies to generate white noise and fragmented speech snippets. Whether the fragments it produces represent genuine spirit communication rather than random radio bleed and pattern recognition is unproven and remains debated among investigators.
How Can I Record Audio From My Soundboard?
Most computer soundboards let you enable “stereo mix” or a similar loopback input in your sound settings, which a recording app can then capture directly. For spirit box sessions specifically, a physical microphone recording the room, rather than a soundboard loopback, is the standard approach since the goal is capturing ambient audio, not internal computer sound.
Can You Actually Talk to Spirits With a Spirit Box?
Spirit boxes generate fragmented audio from rapid frequency sweeps, and some investigators interpret certain fragments as direct responses to questions. There’s no scientific verification that this constitutes two-way communication, which is exactly why recording sessions and reviewing them later matters more than reacting to what you think you hear in the moment.
How Do I Record Paranormal Sounds in Phasmophobia?
In Phasmophobia, you generally need to activate your recording device and the spirit box or parabolic microphone at the same time, then ask questions while both are running, reviewing the captured audio afterward just as you would in a real-world session. The same discipline applies: record continuously and check the clip rather than judging in real time.
What’s the Best Recorder for Spirit Box Sessions?
A dedicated digital recorder capturing uncompressed WAV files at 44.1 kHz or higher generally outperforms a phone for fidelity and dynamic range. HauntGears carries a range of recorders suited to different budgets, alongside guidance on pairing them correctly with a spirit box setup.
