    Epistemological considerations on the metaphysical and spiritualist discourse on this blog

    By Fernando Luis Cacciola Carballal

    There is a variety of metaphysical and spiritualist material on this blog, and, naturally, metaphysical/spiritualist propositions are not scientific. The fundamental feature of a scientific propositions is that they are highly dependable. Science doesn't pretend to hold the ultimate truth, only the truest that we can possibly get at ay given moment. But for all practical purposes, the closest we can get to the truth is essentially as good as the actual, ultimate truth itself. But the w

    Basic setup in Audacity for ITC

    By Andres Ramos

    Audacity is a perfect tool for ITC. If you use it consequently like I am doing since years for ITC you don't want to miss it anymore. To get Audacity you first need to download it here. After installation you can make some basic setups I will show you now and that are optimized for ITC. I configured Audacity mainly along with its usage, thus everything I found out as best practice is empirically found.   First go to Edit->Preferences:   Another menu with lots of tabs

Formant Detection and Synthesis

Voice compression algorithms utilize the common patterns of human speech to detect (at one end) and synthesize (on the other end) voice communication. Among the common structures of speech is the glottal pulse, which is the buzzing "ah" sound that forms the structure for all vowels and certain voiced consonants (like z, v, and r). White noise is the other base sound for forming phonemes like "s", "sh", and "t". Shaping these two foundational sounds are formants, which are the various resonances

Denoising with Machine Learning

Up until the last few years, the only main techniques for removing noise from signals were based on spectral subtraction. Machine learning (ML) has now become a powerful alternative. It takes advantage of the fact that we know what the denoised signal should roughly sound like. I have a paper on this topic here (I'll add a paper download link).  The general principle is we train the ML to convert (noise + speech) -> speech. I use a database of 140,000 seconds of "books on tape." I add ra

Denoising with Spectral Subtraction

If you're doing direct voice ITC, you'll probably be wanting denoise the signals your capturing. The goal of denoising is to remove noise from a voice signal, or equivalently enhance the non-noise, or speech that may be embedded in a hardware noise source. Of all of the methods for denoising a signal, spectral subtraction is the oldest, and most well-known. As the term, spectral, would imply, it involves converting a time-based audio stream into a frequency-based (spectral) vector using the

Direct Voice

After developing and experimenting with the phonetic typewriter, which is a noise-gated stream of user-supplied speech-like sound, I noticed that at times, it seemed like there was a mix of the expected audio and something else. This gave me reason to believe that there could be voices directly from the noise itself. Direct voice, as it were, corresponds to extracting the voices from the noise with no extra audio added in. This method is indeed the original method of spirit communication /

Early video of my phonetic typewriter (January 2019)

Before I make a video showing the phonetic typewriter with my new Python noise gate, here's a video of my original phonetic typewriter using the Maximus noise gate in FL Studio from January 2019. Originally, the stream of audio was alternating between 150 ms speech and 150 ms silence. The gate opened for 100 ms when it detected a high sample. The audio stream I used was always the same recording, starting from the beginning.

Noise Gating (aka the Phonetic Typewriter)

Noise gates are an integral part of most ITC systems. They are a subset of something called expanders, whose job is to expand the dynamic range of a certain ranges of the signal. Below a gate, noise is attenuated. Above the gate, the signal is amplified to achieve more clarity.  If you listen to the raw sound of a typical entropy / noise source, it's sounds pretty boring, as if there's nothing interesting or "paranormal" going on. However, when you expand or noise gate the signal, you empha

The Phonetic Typewriter

When I first started in ITC, I followed the strategies of the tried and true like software Ghost Boxes, but realized I could do better, a lot better... The phonetic typewriter is one of the most popular methods in use by EVP researchers today. However, other ITC researchers may not use that term. They might instead call it a Ghost Box or a Spirit Box. The general concept is that short clips of regular human speech (forward, reverse, from radio, etc.) or similar sounds are used as a base sig

A transition from astral projector to ITC inventor

For many years, I've seen myself as one of those special people who can visit the spirit realms at night during my dreams. So special, that frankly, no one, besides myself, really cares. I could tell you any of the adventures I've had and you'd either think I was going crazy or I was already there.  You see, it's one thing to report to what I'm seeing and hearing and it's another to see it and hear it yourself. Years ago, I dreamt about researchers somehow tapping into my brain while I was
