Electronic voice phenomena (EVP) are the mysterious sound of relieved human -like voices of unknown origin that are heard through electronic devices. They are usually heard in the form of sounds that are printed on an audio recording, but can sometimes be a bit difficult to distinguish. A new standard when recording audio can change that, making it easier than ever to dive into recordings after they have been recorded and concentrate on suspicious EPPs.
Bitrate is an indication of how many samples of the audio are taken per second. For example, an Audio -CD has a bit rate of 44.1 kHz, which is 44,100 samples per second. Which bit depth you tell is how much data is stored in each of those samples.
For the reference, the Bit depth of CD-Quality Saudio 16-bit, which is also the bit depth of various handheld audio recorders, of which researchers are used by researchers to capture EVPs, such as the Tascam DR-05X and Philips Voice Tracer 4110, while the Olympus LS-12 is.
Although 32-bit sounds like nothing more than the next step up, the new size of the floating comma is a bit different than its predecessors because it can taste a hugely superior snapshot of the soundscape. It means that there is sufficient bit depth to catch more than 130 million amplitudes levels per sample. To put that in perspective, 16-bit audio can record around 65,000.
In the world of audio production this is great because it means that Audio will no longer peak in red when sounds are too loud, but this new standard also benefits the world of paranormal research, because it enables researchers to analyze their recordings clearer than ever.
The fact that this is a floating point layout means that it looks a bit like using a high-end camera. Instead of just taking a photo, these cameras make unprocessed data that can be compiled in various ways after the photo has been taken. In the case of a photo you can change things like the brightness and contrast later, but with 32-bit Float-Audio you can adjust the volumes later. So if a sound is very quiet, you will easily be able to strengthen it later without loss of quality.
You will still have the problems of background noise that some researchers choose to filter out of their recordings. 32-bit Float is not a way to filter certain frequency of recordings, but a way to adjust the audio level after recording. In short, if you record something very quietly, such as a whispered EVP, you can turn the volume button later later.
This possibility to manipulate and correct volume levels, opens another common debate … whether you should improve your EPP recordings in the first place. Although logic states that a clear and pure admission is always preferred, many prominent researchers have a trend of manipulating and improving their recordings.
The problem to do this is that if you deliberately manipulate the audio to make it sound more like the words that you think it sounds, what you are left, your ideal interpretation of your own subjective perception of how that EVP should sound, not a real representation of how it sounded when it was recorded.
It is the audio equivalent of distorting a photo or video until it looks like how you want it to look like. An example of this would also be possible to manipulate the audio to sound less like words, which would also be an untrue representation of the sound.
Improving audio generally includes the removal of hisses, hums or other unwanted sounds, a process that irreversibly and subjectively changes the uptake. The tweaking of the volume of a suspected EVP in your admission is less subjective and less destructive, but changing levels removes the context. Stimulating the volume of a sound means that you have no way to know how loud that unknown sound was in relation to well -known sounds that were heard before and then, such as a researcher who speaks.
