Using Curta to calculate is a big flex especially if one has fixed it... put a big smile on my face this one!
SSTV was used in Portal by Valve as part of a new achievement/hidden ARG. When you brought the seemingly randomly placed radios to certain areas they played an audio tone that you could feed into an SSTV decoder to generate images relevant to the ARG.
It was SSTV?! That's really cool
that was my introduction to SSTV and i thought it was so amazing, and the fact one of the images had a phone number that was a dialup FTP run on a PC sitting on the kitchen counter of one of the Portal devs (iirc) was equally as cool
@@kneel1 did someone save anything from the pc?
@@sealed267 yes i think it had copies of all the images from each radio/location in-game and some extras which were all related to hinting at portal2 and its release date
I thought of those portal radios when I heard storing images with sound in the video, and immidiately knew it was the same thing when I heard the sound from the phone.
Loved the unexpected Curta Calculator Cameo
Slow Scan TV is super popular on ham radio. People send photos all over the world from their house radio stations or even in the park, with a wire tossed up in the tree and the radio operating off of battery power. 73 de WU2F
The mid 00s Sony digital handheld recorder brings back memories. I used to bring one to my lectures and record them with a directional microphone pointed at the professor speaking. Each class got its own memory card. I would upload them to my iBook G4 and make them into 128kb MP3s (more than good for just public speaking recordings) and organise those into playlists, I would listen to those playlists constantly on my iPod and in my car (using this cassette tape looking adapter that gave me a AUX line in).
I got my undergraduate degree by memorisation 😂
I'm glad you made it through :)
Here to officially request the _"Janus_ _Cycle_ _best_ _of_ _test_ _mode_ _sounds_ _list"_ please.
Me too
I love the casual use of a portable mechanical calculator as if that’s a totally normal thing to use
I've never wanted something more in my life
It is almost unfair to task viewers with both the calculation of the bitrate of the recorder and drooling over the Curta at the same time. I can’t multitask these.
Respect for using a freaking Galaxy Note 7 😂
Nice spotting. Not sure if anyone would realize.
i thought it was one but why would you be crazy enough to use it? Turns out I was wrong
@@JanusCycle i wonder if they check for this phone at airport
But it you want to fuly charge it you can change battery that been fixed ( new)
6:55 it sounds like from jigsaw movie I WANT TO PLAY A GAME thats what you neded to say
When he said "I really don't want it to blow up" cracked me up!
When I saw that thumbnail I thought you're going on a journey into that weird time in the voice recorder industry when everyone tried to push features into them super hard. As a result I used to have a voice recorder from Olympus in 2004 which did indeed have a camera and take pictures! You couldn't listen or view them but you could drop them onto your PC after the fact
That is good idea to send congratulations postcard to my friends, just record this kind of trek :)
Top quality as always. Thank you for posting :)
Oh yeah, more importantly, thank you for making excellent
intelligent and interesting videos on obscure topics.
I'm getting Posy vibes from this video, I like it.
I'm in great company then :) I'm honoured, thank you.
Surprisingly good results for mp3 codec.
it would be cool to see how well the tape recorder works through the direct connection
The International Space Station ISS is also sending SSTV some times. Thanks for sharing.
I tried to find out to see if I could get the signal. Then I missed the December 2023 passover.
@@JanusCyclePassover in 2023 was in early April, your Rabbi must be extremely disappointed in you
@@RaytheonTechnologies_Official Its currently sending SSTV out, been doing it since Tuesday and ends on Monday
@@Ben1551 the festival of Passover is unable to do that, you must be picking up signals from a different Jewish festival
If I had used two separate words pass and over this may not have happened. But I did enjoy reading this.
This calls for a "SSTV to Speech" and "Speech to SSTV" converter, to give us the best image quality with that voice optimized audio codec. 😅
I'm so happy a random Northern Exposure clip wound up in here with Ruth-Anne Miller smashing Maurice's device. I miss that show!
Ended up
Cicely is such a beautiful town. I live there in my mind whenever I see an episode :)
That’s an amazing technology this is responsible of all the images and data sent from the moon, mars and all those deep space missions like the voyager, and it’s still in use helping sailors to have a daily forecast weather report, really useful for vessels that won’t have access to satelital services for any reason, and a great chance for radio enthusiasts to experiment on data transmission
I love everything about this video and I want to buy all the things you used here. Extremely interesting and satisfying.
ROBOT36 is one of the fastest modes, but also one of the lowest quality.
i loved messing around with sstv when i was a kid
Would’ve been cool if you yet the sound play without commentary so we could’ve downloaded the app recorded at home.
Good suggestion, next video with SSTV will include something like this.
11:00 I would never imagine the digital recorder would do worst.
Lmao using RLM as the reference video for ghost hunting is great.
Those guys :) I'm happy they make these kind of videos.
That RLM video mentions how unserieous it is to use voice recorders for ghost hunting, you should use something designed for raw CD quality PCM like the Zoom recorder they used.
I want to believe myself but not enough to find it buried in compressed artifacting and audio pareidolia. I recorded a great example of this from a Discord stream of my friend using a shop vac. The vacuum cleaner sounds like it has voices in it because that's what the encoder is looking for, it's eerie!
I still think this voice based codec would be useful for 'hearing' EVPs. And I think Mike would have fun listening to these sort of recording artifacts until Rich calls out his bullcrap.
Nice to see you working a Curta to calculate things. Never knew tat such mechanic calculators are doing that job with sucn large numbers so accurate. 🙂
So much more satisfying than an 8 digit calculator, or an app on your phone.
Some of these distortion patterns look awesome. I gotta give this a try myself if I can find a good recorder for it. Imagine how cool it would look if you ran every frame of a video sequence through one. It would look great played back on a little screen for a grungy scifi/cyberpunk movie.
Excellent choice in music for this video.
Yeah, nice vibes to match
This upload was absolutely fascinating ! 1960's tech on 2020's hardware 😁👍
I'm guessing the digital recorder audio compression was a big factor. I wonder if LPEC was a derivative of Sony's ADPCM MD compression format ?
Given the amazing results with MP3, it would be interesting to see the results using OGG Vorbis, WAV and FLAC...
It’s because the tape is analog and the other recorder has small gaps we can’t hear but the microphone can. That’s my guess.
Yeah. Played bitrate must be synchronized with the recorder sampling.
It’s a really good visual demonstration of what a dac can do to a signal.
I kept thinking there was something hinky with the audio compression but I thought it was MP3 compression so both the discovery of the actual codec and the demo o at the end of MP3 left me dazed
Not the same but when i was doing the final project for a degree in IT back in 2009 i didn't have an internet connection at home, so me and my friends send each other word files compressed into .rar, added them at the end of picture files using the '+' command on CMD to make them into images you could send through MMS. Felt like hackers
That is awesome! I love hearing about this kind of stuff, thank you.
Can you provide a link to the schematics of that 3.5mm headphones output to microphone input thing?
Yes of course,

@@JanusCycle Thank you.
P.S.: UA-cam comments are weird, it showed your reply an hour after it was written.
This was amazing..!
An interesting test, pity you muted and talked over the SSTV, making it impossible to decode at my end and see what the UA-cam audio system would do to the images.
I was mucking about with RTTY the other day to see what audio codec's would do to that, however as it has a far lower data density than SSTV I was unable to corrupt it, even using the lowest settings I had. Unfortunately I don't have a Sony digital voice recorder so no idea if that would do to the messages.
This won't be the last time I play with SSTV in a video. Thanks for your suggestion. I will find a way to do this creatively next time so everyone can participate.
Can't wait for the "top 10 test modes of all time" video
Nice I will have to try this with my Olympus L400 Pearl Corder. The world's smallest autoreverse micro cassette recorder.
Oh, that is one beautiful peace of hardware you have there. I feel the envy :)
5:40 - Yes, please.
I guess that the codec used in the earlier SONY voice recorder is in fact vocoder-based codec.
Samsung be like: Google, help, this headset knows karate!
This is really cool. I'm wondering how well that would work between two cell phones using whatever stock voice recorder app is on them. Imagine a bizarre scenario where your phone's Bluetooth, data network or Wi-Fi connection wasn't working, the SD card corrupted, and wanted to receive an image.
my old metronome had a calibration mode documented, but if you held some extra buttons the test mode would come up and play a melody
What if you tried running an audio line out from the phone to the mic in on the microcassette recorder or using a cassette that can record in stereo, does your sony recorder have stereo input? I see it has a stereo mic. This is really cool I didn't know this existed, aside from using cassettes to save data like games or apps on older 8bit computers. I have a bunch of old microcassette and cassette recorders and it makes me curious enough to try this.
Primer is such a great movie (once you watch it the third time)
It's like it was designed to be rewatched.
Voice codecs in CDMA and GSM phones also operated at ~ 10kbps range. Maybe they used similar technologies on them, too.
Your Digital Recorder has Noise Reduction And lower Bitrate Messing With SSTV And Almost Every Ham Radio Digital Mode Is Messed Up Except For Morse Code
weird gadgets will forever be amazing
It'd be cool if you did this with a Sony Clie since that would use ATRAC like MiniDiscs did; although I'm not sure how much the speaker would do the audio justice, Lol.
Like that microcassette recorder I also happen to have a solid state voice recorder made by (or sold by, idk) Olympus, much less features than the Sony shown here.
(I also have a full size cassette voice recorder made by GE, all three from my Grandma)
I really like the Curta cameo, such a mechanical marvel that thing is.
SSTV always intrigues me, idk why though, Lol.
Ahh MiniDisc, the topic I have yet to cover. I like your idea of trying these experiments out with the format. This is worth trying one day.
Love your videos
Was that a shot of the movie Primer? Awesome!
I was thinking about past and future and rewatched Primer when making this :)
OK, I was confused when I looked up and Red Letter Media were on and I thought my UA-cam streams were crossed!
my introduction to SSTV was the Portal radio update easter egg, so was really late to the game
Dude. Did you get some RLM shout out in my Janus Cycle video?
Second mention about evps from someone in a day. 'tis the season I guess. :p
10:29 .... Yeeeeah ❤❤❤❤ john wick 4 is here
Psychoacoustic compression removes audio that is supposedly inaudible to the human ear as well apparently the analog converted digital you're recording.
Nice!
I have a cheap sound recorder, it just records plain old wav files into its internal 4GB memory in mono, the internal microphone is a bit too easy to overdrive, but it's usable with an external one.
"Digital voice recorder | Made in China" ← It does not have even a model number on it!
🙂 I figured out a trick: when something is too loud, I set the recorder to treat the external microphone as a "line in", the recording can be boosted later on a computer.
oh my fucking god you actually use a galaxy note 7, i envy you
I *carefully* use a Note 7 :)
Didn't Samsung send out a kill firmware for the phone?
They did release a fan edition..
Yes, the kill is still out there lurking. But I've managed to be careful and avoid it so far. My Note 7 is still the original before the FE.
There is some numeric typo in subtitles when calculating audio bitrate. Like 16:19
i have been playing around with that sstv with my radios off and on for a few years. i think of it as sort of a modem type thing. its a very similar concept to the old dial up modem thing., but i never thought about storing the audio as, well, audio that is clever, espeicaly using old mini cassettes
once i first heard that sound i did everything i could to never hear that sound again with how i set things up. this would be a neat way to store your sweet porn pix
The lossy compression on that digital recorder really butchers the image quality.
that's really cool tho
" i once saw him Sending 3 photos To smartphone with a Sony digital recorder " ! With a facking degital recorder !!!! 😮😮
i think using the mic in and the headphone jack could help
Explosion roulette
Maybe next time :) Until them back in it's fireproof storage box.
@@JanusCycle probably for the best haha
for the note 7, you might be able to use an s6 oe ote 6 or s7 battery or whichever fits
Those hack frauds didn't even catch a single ghost.
I bet you they will try again. Mike can't let it go.
Try it with a recorder or a PC that can record an uncompressed wav file.
8:23 you can hear how the audio sounds compressed here.. unlike with the tape
edit: he explains it later
19:56 That didn't happen that much in real life 😊
But that's not the impression I get from watching 90s TV :)
Would love to see a follow up video doing the same thing on MiniDisc recorders - would be interesting if the more general purpose nature of their codec would work better. Could try early and late recorders and codecs to see how they improved or got worse (in the longer playing later codecs). Thanks as always for a fascinating video!
This is a stellar idea! And then take it even further with video recorded on MiniDisc! Ok, maybe one day, let's see what happens.
How about the PXL2000
I tried something similar to the PXL2000 in an older video. An experiment I plan to revisit one day.
The ZX spectrum used this back in Europe. Someone did a video in a way that you can actually record this at a high speed to jam more data and video on a regular cassette tape. ua-cam.com/video/MAIsOIwgJWA/v-deo.html
im suprised that phone didnt blow up during this video
PXL-2000 by fisher price.
69 lesssgooooooooo
8:52 the speaker of the digital dict isnt the best, thats why robot36 doesnt display good image
Well, I did address that later . .
Later a direct connection was made in the video, but that doesn't produced as good quality as the micro cassette recorder did.
@@zsombor_99 I would try a better speaker , connected to the dictophone, just to try. With a decent amp
@@Maevmm That Sony audio codec is not good enough, the direct connection proved that, I think.
Yep, it's codec. I did a direct connect to the mp3 device at the end and perfect reproduction compared to any of the speaker/mic tests.
You did this whole video just as an excuse to use your Curta, didn’t you?
lemme guess.. sstv?
yeup
NBTV next time I experiment like this :)
@posy would love this! 😊
Now send video.
Ok, I'll do this in a future video!
