How to monitor night sleep ? (Recording audio at night/durin

Hello,

Serious question:

Let's suppose strange things are happening at night, for example:

1. Neighbours making noises, talking, bumping doors.

2. Animals outside.

3. Planes flying overhead.

4. Toilets being flushed.

Just weird stuff or just stuff that might be influencing your sleep.

You kinda want to get to the bottom of it, to tell if it's real... to tell if it's truely there... to tell how violent or intrusivive it is.... to tell the severity... and perhaps even to convince others.

Mostly what you would want is an "audio-recording" device that can:

Monitor/record audio at least for 10 to 12 to 14 hours straight.

That stores it on some digital media.

That can be processed with tools... preferably goldwave editor... thought it seems limited.

The mic/microphone should be able to record any kind of sound... low bass, medium frequencies, high frequencies and from any direction if possible.

What kind of device would you recommend ?!

If such device does not exist... well then perhaps design one...

Offer it for sail as:

"Night tracker" or something or

"Sleep monitor" or

"Sleep tracker" or

"Night audio surveillance" or

"Sleep overwatcher" or

Something creative you can come up with.

"Night protector"

Perhaps it will sell.

An SD as story device or perhaps an USB drive as storage device would be preferred be me for easy transfer to PC for analysis and perhaps even transport to others.

Let me known your recommendations !

Bye,
Skybuck.

https://www.bhphotovideo.com/c/buy/Portable-Digital-Recorders/ci/14934/N/3992462091
has a whole bunch of devices which will do what you want.

For one example, the Tascam DR-05X records on microSDXC cards of up to
128 GB in size, in stereo (omnidirectional microphones are attached,
and you can plug in external mics if you wish). Battery life is up to
17.5 hours.

There's a similar but somewhat less expensive model made by Zoom
(shorter battery life, limited to SDHC cards of up to 32GB).

Since these write in standard formats such as .wav you can transfer
the recording files to a PC and use GoldWave or Audacity or CoolEdit
or whatever you like.

I haven't used either of these specific models, but looks as if either
of these would probably be capable of recording every sound in your
room, from the time you go to sleep until the moment you wake up
screaming with an alien face-hugger attached to your nostrils.

Or, just use a recording app on a smartphone.

There are lots of devices to help track your sleep.
A friend just gave me a Fitbit Charge 3 wrist sensor,
which advertises saving details on when your sleep is
disturbed, etc. That would you where to look in the
sound file for clues. "Automatically record time spent
in Light, Deep and REM sleep stages and see activity
trends, health insights and personalized guidance..."

Also, we have a weather-clock that projects dim red
digits onto the ceiling. If you are awakened, you can
glance up and make a note of the time, before going
back to sleep. But best advice is, ignore all that
stuff, to improve your chances to get back to sleep.

Very late in my father's life (like about age 90) he experienced some
cognitive decline that caused him to believe there were people looking
in his windows at night and moving around the apartment while he slept
making a ruckus. a couple times I did just set up a camera and showed
him "nothing there, Dad" which convinced him for a while but the
feelings would always return eventually. Anosognosia I believe it's called.

Ok thanks for the suggestion, however the mic seems a little bit tiny ?

Where you perhaps thinking of aliens or burglars spotting it/seeing it and then perhaps avoiding it ?!

This is not really the case in my situation.

So the equipment can be pretty big if necessary.

Ofcourse compactness does mean I could use it elsewhere anyway... perhaps to spy on people.

Granted it's a little bit like spieing, perhaps even a lot.

But my primary concern is "audio quality".

I want the recorded audio quality to be of as high quality as possible.

And yes the omni directional is very nice/cool that's exactly what I want basically... being able to record from any direction or at least something like 180% or something...

I can understand if back side picks up less... 360% ofcourse would be ideal.

But I could try and reposition the 180% equipment next night to see if it records anything different.

So giving this new/extra information that size of recording equipment is of no true concern as long as it will fit in the room.

Will/would you now pick a different device ?

Bye,
Skybuck.

The specs for the DR-5X show it handling the whole audible frequency
range (20 - 20,000 Hz) with good frequency response. However, this is
quoted for using the "external in" jack, not the built-in
microphones... they don't say what the mic's own frequency response
is.

I would guess that it's pretty good, since most electret microphone
capsules are wide-range, but probably not as good as an expensive
external microphone.

If you want a really large microphone or two (stand-mounted perhaps)
you can use 'em, and connect them to the "EXT IN" jack.

>Where you perhaps thinking of aliens or burglars spotting it/seeing it and then perhaps avoiding it ?!

No. It's just that these are the least-expensive sorts of devices
that I think are capable of making recordings of the sort that you
would need for your investigation.

I don't think there's a chance in 10,000 that you're going to detect
anything that's truly unusual - aliens, burglars, paranormal
cross-dimensional body snatchers, or so forth. Random building
noises, footsteps, voices from next door or outside, the scurrying of
pets or vermin - sure. Even a simple portable digital recorder would
be good enough to record those and let you figure out what they are.

This is not really the case in my situation.

So the equipment can be pretty big if necessary.

Ofcourse compactness does mean I could use it elsewhere anyway... perhaps to spy on people.

Granted it's a little bit like spieing, perhaps even a lot.

Spying on yourself (or your sleeping room) is safe enough... it's your
space.

Spying on other people might be a criminal offense, or a civil tort,
or might result in you being punched by the people involved. I don't
advise it.

But my primary concern is "audio quality".

I want the recorded audio quality to be of as high quality as possible.

"As high quality as possible", without a budget being indicated, is
what throws your question into the area of what some call
"audiophoolery". There are certainly plenty of people who will be
glad to sell you a set of two-meter microphone cables (conductors made
of virgin silver, mined by Church-certified virgins and lovingly
basted with pyramid-energized holy water) and claim that this somehow
improves the quality of your recordings.

And yes the omni directional is very nice/cool that's exactly what I want basically... being able to record from any
direction or at least something like 180% or something...

I can understand if back side picks up less... 360% ofcourse would be ideal.

So, study professional microphones and find the sort that you want.

Omni is easy. Mics with a cardiod pattern would let you "aim" them
for greatest sensitivity in a particular area.

The one sort you would _not_ want would be "noise canceling". These
are intended for close-to-the-mouth speech recording, in noisy areas.
They are deliberately designed to be as insensitive as possible to
sounds arriving from a distance.

But I could try and reposition the 180% equipment next night to see if it records anything different.

So giving this new/extra information that size of recording equipment is of no true concern as long as it will fit in
the room.

Will/would you now pick a different device ?

If you want big-and-bulky, what you'd probably want to do is buy a
multi-channel audio mixer/recorder with several microphone inputs/preamps,
and a set of several stand-mounted microphones.

https://www.sweetwater.com/c1008--Digital_Multitrack_Recorders
shows a whole bunch of mixer/recorders of this sort - some portable,
some intended for desk or rack mounting.

https://www.sweetwater.com/c105--Condenser_Microphones has
microphones. The Neumann TLM 103 is probably wonderful, but they're
$1100 each.

You can easily spend five or ten or twenty times as much, on a complex
setup like this, as you'd spend on one of the little portable
recorders. Frankly, for a research project of the sort you're
considering, I think it would be a huge waste of money - you'd be
unlikely to learn enough more to justify the expense. Even the little
portables, with their built-in condenser mics, should be perfectly
capable of capturing a high-fidelity recording of snores, traffic
noise, the occasional flushing of a toilet elsewhere in the building,
and the odd outburst of flatulence.

If you do throw together something involved, make sure you pay
attention to proper RF shielding and grounding. It's easy for cables
to pick up radio frequency transmissions from nearby radio and TV
stations, cabs, police and fire radios, ham radio operators, etc. and
these can result in "voices" on a recording. People have often
confused these for e.g. "spirit voices", while there's actually
nothing mystic about them at all... they're purely accidents of
technology.

 

Ok what I have learned from you, Dave Platt, is that I might want to buy an "omni condensor microphone".

I see the price range is massive. You asked for price point, I do want to have something quality. I might re-use it for gaming later =D If I wanna give away my voice... or maybe even youtube commentary.

So a price of 200 euro seems somewhat reasonable. I am not sure if the mic could be re-used for youtube videos... maybe not... and maybe not for gaming... probably not... that would be kinda shitty... not sure, what you think ?

Anyway my eye fell on this/these ones:

https://www.sweetwater.com/c105--Omnidirectional_Condenser_Microphones?params=eyJmYWNldCI6eyJQcmljZSBSYW5nZSI6WyI0Il19fQ

Maybe I should look for something more cheap.

However how does one connect such microphone to for example a computer ? Is it a simple 3.5mm jack that goes into a soundblaster or is this something different ?!

I could ofcourse also go for the original solution you showed... it would be more portable and such... and this would also be a great adventage... then I don't need to leave PC on and there is no risk of my PC being unattended.

Or I would have to go to a hybrid solution.

However I would prefer a solution that:

1. Does not require my PC to be on.

2. Does not require batteries and can simply be attached to power socket in wall. (This will probably make it less portable).

The battery option seems kinda nice... I assume original solution uses it. However then it does require charging and such... and this might make it less applieable.

What if I want to record multiple days ? Or even weeks or months... ?!? Hmmm.

Not sure how much time/audio the original solution can store ? (It's very late now will have to re-check later).

3. Is omni directional

4. Total cost 200 euro's which I think is already a lot, cheaper would be nice...

But it has to be able to record any kind of sound that could wake a person up basically, even if person is wearing ear-plugs.

So perhaps a cheaper solution is warranted, since I do sleep with ear plugs..

However... the weird thing is... the ear-plugs work like a "low pass filter".

Some higher frequencies are not stopped by the ear-plugs so I can still hear some higher frequencies sometimes... like human voices perhaps.

So it would still be interesting to have "high quality" audio.. meaning entire frequency range.. and also pretty good volume/amplitude(?) range.

Kinda sucks it has to be so expensive, but I guess you electronics people need to eat too ! LOL.

One guy gave me a mic once... it was just 2.5 bucks... so I guess my mind is a little bit warped/twisted about mic prices

It could be snapped onto t-shirt... but the sound quality was pretty terrible I guess.

I once also had a microphone with soundblaster... but I think it was also shit... or it just me finding my own voice weird not sure... not sure where that microphone went... I don't think it fitted into soundblaster anymore.... so it was useless.... maybe it needed a special plug or something can't remember... never been a fan of these things.. they could be heavy too.

Hmmm.

5. Something on a stand might be nice... so it's not effected by earth/voltages or strange intereferences.

I wish I could go some place locally to test this stuff out.

I don't know of such a place... hmmm...

Also thanks for the voices explanation... there is that tv-show on tv... ghosthunters... maybe that's what they are picking up... me wonders...

Bye,
Skybuck.

 

Hmmm one thing just popped into my mind.

I could try and visit a music equipment store for gitars/synthesizers and such... perhaps they also have "recording equipment" in the form of microphones and such... not sure... but it's worth a shot

Bye,
Skybuck.

200e for a mic for this is absurd. 1e for a condenser mic insert is fine.

those are studio / performance microphones with XLR connectors, they
possibly need "phantom power", but hey that Tascam recorder looks
compatible if that's how you want to spend your money, Personally
I'd stick a 16G SD card in a cheap personal recorder and see what
that picks up first.

Maybe I should look for something more cheap.

However how does one connect such microphone to for example a computer ? Is it a simple 3.5mm jack that goes into a soundblaster or is this something different ?!

probably need some sort of pre-amplifier

most of the really cheap microphones are reasonably omidorectional

You can make a stand with a stick and some rubber bands
this stuff doesn't need to be expensive.

I wish I could go some place locally to test this stuff out.

I don't know of such a place... hmmm...

There should be some place locally, you could try a large musical
instrument shop, if they don't have that sort of stuff they'll know
who does.

I doubt it. Mostly crap these days from stores like that unless you spend

their outside broadcast interviews, so you're not going to be
disappointed. Being the BBC of course, most of the people they
interviewed were Marxist c*nts, but you could hear the rubbish they
spouted beautifully clearly.

Completely pointless. Cheap electret/condenser mics work great for surveillance.

You're talking about two different (acoustic) situations and problems
there. A single microphone isn't likely to give you good results for both.

For recording ambient sound, you want one or more omni microphones.
Quite honestly I think the little electret mics build into those
portable digital recorders would work fine for that.

For voice use (either YouTube or gaming) you probably do *not* want an
omni mic. The mic will pick up both your "direct" voice, and echoes
from within the room, giving your voice an echo-y or "space-y" sound.

For better results with voice, you'll probably want a mic with a
cardioid pattern (heart-shaped - "ignores" most sound coming from the
back) or a close-to-the-mouth "noise canceling" mic such as you'll
find on a good gaming headset (these are less sensitive to sound from
more than a few inches away). Either of these will give you a clearer
voice signal than an omni is likely to.

It's possible to buy professional mics with a switchable pattern (omni
or cardioid) but my recollection is that they're quite expensive.

Start simply. Use a good portable digital recorder, run it for a few
nights, and see if its built-in mics are giving you a good enough
signal. If not, you can always spend more money later on better omni
mics, cardiods, or others that you can plug into the recorder.

Indeed, but the OP said he might want to use it for Youtube vids at some
stage as well, hence the suggestion.

Good luck and happy ghost hunting.

He doesn't need a ghost box but it might be the same phenomenon at play. Snippets of sound strung together being interpreted as a voice.

Some of those EVP recordings demand an awful lot of 'creative
interpretation' on the part of the listener.


EVP "Extra Voluntary Palpitations"

Ya did it to yerself! Ain't no dang 'spirits'.

Or "Extra Voluntary Pussifications"

Yer daddy taught you to be wussified about those non-existent
'spirits'.

Likely choice "A".

Ghost do tend to play a little, but most of the time, they just hang
around and try to look intimidating.

He wanted:

Mostly what you would want is an "audio-recording" device that can:
Monitor/record audio at least for 10 to 12 to 14 hours straight.

Recording 10 to 14 hrs of near silence is easy enough. Playing it
back, looking for something interesting is tedious, dull, boring, and
a huge waste of time. Some kind of silence eliminator or sound
detector might be useful to limit the recording to only genuine ghosts
or whatever. Of course, if he snored for 10 to 14 hrs, such a device
might not work. I could probably convince Audacity to provide such
"silence elimination" feature.

I had the problem recording 2-way radio scanner audio. Most of it was
dead air. So, I used Scanner Recorder, which eliminated most of the
boring silence:

Here's another which I haven't tried:

He also mentioned:

>> Just weird stuff or just stuff that might be influencing your sleep.

Oddly, he wrote "your sleep" and not "my sleep" which suggests a
product made for other people, not for the OP. While he might not
need a ghost box to record weird things the go thump in the night, it
would certainly be a concern for potential buyers.

Incidentally, back in the days of 1/4" stereo tape recording, I was
hearing similar strange voices from the dead on some tapes. These
machines would record 2 tracks in one direction, and then an
additional 2 tracks in the other direction, with all 4 track
interleaved. The combination of "print through" and "bleed over" from
the reverse tracks produced the mysterious sounds. Since the "bleed
over" sounds were being playing in the reverse direction, they sound
quite strange.

Another source ghostly voices is ham radio Field Day.
<https://www.google.com/search?q=ham+radio+field+day&tbm=isch>
That's 24 hrs of extracting call signs and grid squares from under an
audio jumble of simultaneous static, interference, intermod,
heterodynes, generator noise, and electrical buzz. After Field Day
had ended, I was still hearing weak voices and call signs buried under
every day noises for several days.

Of course, the voices might be real. It might be a conspiracy
intended to drive the OP insane:
