ECHOVOX turns your phone into a paranormal research kit — EVP recorder, Spirit Box, EMF meter & ITC device. Studio-quality audio, real-time readings, fully offline. Free trial, no account needed.
How well does the offline spirit box mode actually perform without any internet connection for frequency sweeping?
@esmasagtekin The Spirit Box runs entirely offline — it uses your device's hardware radio tuner to sweep real AM (530–1710 kHz) and FM (88–108 MHz) frequencies. No internet is required at any point. Sweep speed, band selection, and response capture all work fully without a connection. The only feature that requires internet is the ECHOVOX ITC Device (Voice Q&A), which uses server-side speech synthesis.
How does the Spirit Box mode actually sweep through radio frequencies fast enough to capture usable EVPs without sounding like static on every session?
@ebubekirna9spz Great question. EchoVox delivers that same authentic sweep experience real Spirit Box/PSB7 users know — rapidly cycling through audio fragments at sweep-comparable speed, tuned so each fragment is long enough to form a potential word without collapsing into static. It also records the raw sweep separately, so you can slow down and isolate moments after the session instead of relying on catching it live.
Worth being upfront: like any spirit box, this lives in audio pareidolia territory — I built it as a tool for the practice investigators already do, not a claim that it's receiving anything. That honesty matters more to me than hype.
Offline mode is a nice touch for actual field use, and the EMF readings felt responsive during a quick test in my basement. Curious to see how the spirit box scans hold up in noisier environments.
@toprakbaavkroc Thanks so much for trying it out and sharing this feedback, really appreciate it!
Glad offline mode is working well for field use, that was a priority for us since a lot of investigations happen in dead zones. Good to hear the EMF readings felt responsive too.
On the spirit box side, noisier environments are still something we're actively tuning for, so your basement test is useful data. If you get a chance to try it in a busier/noisier location, I'd love to hear how it performs, that kind of real-world feedback really helps us improve it.
Tried the EVP recorder during a quick session at home and the audio clarity genuinely surprised me for a phone mic. The offline mode is a nice touch for actual field work without worrying about signal.
@atakansiler Really glad the clarity stood out — that was actually one of the harder things to get right. Phone mics are optimized for voice calls, which means aggressive noise suppression and compression that's great for talking to someone but terrible for catching faint ambient audio. Had to work around a lot of that default processing to preserve the raw signal quality EVP work actually needs.
And yeah, offline mode wasn't optional for me — most of my own fieldwork (13+ years investigating) happens in basements, old buildings, remote sites where signal is the first thing you lose. Built it assuming zero connectivity, not as a nice-to-have.
What kind of space were you testing in — open room or something more enclosed like a basement/closet? Curious if the clarity held up the same way.
Tried the EVP recorder last night and was surprised how clean the playback sounded even with background noise. The offline mode is a nice touch for field sessions.
@miranpma That's great to hear — background noise handling was actually one of the trickiest parts to get right. Most recorders either suppress everything (which can wipe out faint voices along with the noise) or don't filter at all (which buries the signal). Had to find a middle ground that keeps ambient texture intact without drowning out anything worth catching on playback.
Offline mode was non-negotiable for me too — most real field sessions happen in basements, old structures, remote locations, exactly where signal drops first. Wanted something that works the same with zero bars as it does at home.
Was this an indoor session or more open space? Curious how it held up either way.
Tried the EVP recorder last night in my basement and the playback clarity actually caught a faint voice I never would've noticed on my regular voice memo app. Offline mode is a nice touch for spots without signal.
@caner334669 That basement catch is exactly the kind of moment I built this for! 🙌
Fun fact — the reason regular voice memo apps miss those faint voices is gain/noise-floor handling. Most stock recorders auto-compress quiet sounds to avoid clipping loud ones, which is great for normal use but terrible for catching something faint under the noise floor. EVP work needs the opposite — preserve the quiet stuff even if it means more background hiss to filter through later.
Offline mode was actually one of the first things I insisted on — most of my own investigations (13+ years in the field) happen in basements, old buildings, remote sites — exactly where signal disappears. An app that needs internet to function in those spots defeats the purpose.
Did you get a chance to isolate/clean up that voice on playback, or still working through it? Curious what you picked up.
