Necrophonic

Review by eFreeware

What sets Necrophonic apart from most apps in this corner of the store is the audio itself. Instead of handing you a single sweep of noise and leaving it at that, ChillSeekers built eight separate sound banks out of phonemes, fragments of words, reversed speech and snatches of foreign languages. The idea is that this material gives whatever you are listening for something to shape into words, rather than a flat hiss to interpret from scratch.

That makes it a tool rather than a piece of entertainment. It is for people who already take instrumental transcommunication seriously, or who want to start: hobbyist investigators, paranormal groups running sessions, and anyone keeping EVP recordings and comparing them afterward. If you are curious about the field but not ready to spend on dedicated hardware, an app like this is a low-friction way in.

It is a paid download at $9.99, with no advertising and no in-app purchases attached. The rating sits at 3.8 from 3,503 ratings, and the install count has passed 100,000 since the app arrived in June 2018. The developer has kept it current, with an update in October 2025.

Eight banks of phonemes instead of plain noise

The core of the app is those eight active sound banks. According to the developer, the audio was mastered in Pro Tools with the high, mid and low frequency ranges boosted, and further filters applied to give each bank its own character. The stated goal of that processing is to layer the audio and create an environment suited to spirit communication. I can see the logic: if every bank sounds the same, switching between them achieves nothing, so the processing is what makes the bank selector useful.

What is inside the banks matters more than how they were made. They are built from phonemes, partial words, reverse audio, foreign languages and other pieces of speech, with basic phonetic sounds such as na, no, da, do, di, ma and may doing much of the work. The developer is explicit that the banks contain no real words or phrases. For EVP work that is the point: you supply the interpretation, and the app supplies raw material that is suggestive without being leading.

Anyone familiar with the developer's earlier Spiritus Ghost Box will recognize the approach, since Necrophonic plays its banks in a similar way. The difference is scale, with eight banks here against four there. More banks mean more variety across a session and more combinations to try, though they also mean more time spent learning which ones suit your setup.

The DR60 white noise bank and the two effects

Alongside the eight main banks there is an optional ninth. This one is white noise, but not from a generator: the developer says it was taken from the internal sounds of the DR60 recorder, the device EVP researchers treat as the standard. It can run on its own or layered with the other eight, which effectively gives you nine banks to work with. The distinction between a DR60 sample and synthesized noise will matter to people who have chased that particular texture; to everyone else it is simply another option in the list.

The app also includes echo and reverb. The developer calls these the best effects to apply to ITC sessions, and describes two different jobs for them. Echo repeats the audio, which can help during live listening by giving you a second pass at whatever came through, and it also creates a layer that can be manipulated inside the echo itself. Reverb widens the sound into a more spacious environment, which can help with audio manipulation.

In practice these are the controls that turn a bank into a session. A dry, unprocessed bank is hard to work with over a long stretch; echo and reverb give you room to adjust how the audio sits and how much of it you can pick apart by ear.

What the app asks of you

Necrophonic is a one-time purchase of $9.99. There is no advertising in the app and no in-app purchases, so nothing inside it is gated behind a second payment. For a niche tool with a long update history, that is a straightforward arrangement: you decide once whether the feature set is worth the price, and the cost does not recur.

The app is rated Teen, which is worth noting if you are buying for a younger household member or running a group session with mixed ages. Beyond that, the requirements are mostly about you rather than the phone. ITC work is a listening practice, and the app gives you the source audio and the effects; the patience and the method come from your side.

It is also worth setting expectations about what the banks contain. Because there are no real words in them, nothing you hear will arrive pre-formed. The app is built to be ambiguous, and that ambiguity is the working material rather than a flaw in the design.

Getting something out of a session

The most useful habit with a bank-based app is to start narrow. Pick one of the eight banks, leave the others off, and listen for a while before adding anything. When you do start layering, the white noise bank is the natural first addition, since the developer designed it to sit either alone or underneath the rest. Working up to all nine at once is an option, but it is a harder listen than most people expect on a first attempt.

Echo is the effect to reach for when you are listening live and want a second chance at a passage; reverb is the one to reach for when the audio feels cramped and you want more space around it. Try them one at a time rather than together, so you can tell which one is changing what you hear. Recording sessions and comparing them later is standard practice in EVP research, and it is the only way to check your impressions against the audio itself.

The bank selector rewards a bit of note-taking. Each bank has its own frequency character, and which ones work for you will depend on your headphones, your room and how you like to listen. Keeping a short log of which bank and which effect settings you used for a session makes the next one easier to set up and the results easier to compare.

A focused tool for people already doing the work

Necrophonic does one job and does it with more care than most apps in this space. Eight phoneme banks, a ninth white noise option drawn from the DR60, and echo and reverb controls cover the essentials of an ITC audio source without padding the app out with extras. The developer's background in this niche shows in the decisions: no real words in the banks, processed frequency ranges, and effects chosen for how sessions are actually run.

The price is the main thing to weigh. At $9.99 with no ads and no in-app purchases, you are paying once for a tool that has been updated as recently as October 2025 and has built a user base past 100,000 installs. A 3.8 average from 3,503 ratings suggests a mixed but largely positive reception, which is typical for an app whose usefulness depends heavily on how the buyer intends to use it.

If you run EVP sessions, investigate with a group, or want a serious audio source for ITC work without buying hardware, this is a sensible purchase. If you are looking for something to entertain a room for ten minutes, the app's deliberate ambiguity will not give you that. The people who get the most from it are the ones who already know what they want to do with a bank of phonemes.
