The Evolution Of Music Storage
HTML-код
- Опубликовано: 16 авг 2019
- The field of audio evolved over the last 170 years starting with the human voice first being imprinted on paper covered in soot, on a device known as the phonautograph. It would evolve into the wax cylinder phonograph and eventually the disc-based one, we know today.
Mechanical sound storage would be replaced by electrical-based sound reproduction, via microphones and loudspeakers. The sound could now be transmitted over lines and via radio.
The medium of vinyl records would soon be accompanied by the advent of magnetic tape storage. Magnetic tape storage allowed for sound editing and convent storage. As well as being able to be transferred into other mediums such as optical audio.
Electrical sound storage also brought the concept of signal processing with it. The frequency components of sound could be analyzed and modified to enhance quality, fulfill storage needs, and for artistic effect.
Several common audio signal procession techniques discussed are audio filters, dynamic range compressors and noise reduction.

This channel is underrated. This was such a great mini documentary!
This is so jam packed with info without being overwhelming. Well done.
yeah, it felt like a whole crash course on audios.
10:36 will watch later
Ahh you’re back! I learn so much from these videos more than I do in school 😂
You'd probably learn more in school if you weren't distracted by that sexy teacher.
=%gmhht5
1:34 when you join a casual match in cs go ಥ‿ಥ
This is the most in-depth EQ tutorial I have ever seen!! This video would saved me so many headaches when I started working in musical theatre 🙃
I really like the depth intensity of the content. Nice Video & Worth watching 👍✨💜✌
You're better than most of my professors at uni. Seriously, the amount of info presented without being overwhelming or boring is insane!
This video was all my teen years...
I'm really glad I subscribed to this channel!
I love your narration!
Brilliant! That's the most useful tutorial on the subject that I've seen for years. Peace and blessings!
8:22 A logarithmic scale would be better suited for diagrams related to sound.
Yeah, but it's harder for most people to understand
@@Felipemelazzi it shouldnt be. but yeah, i agree that it is.
I can't get over how good your videos are.
I love this subject! Glad I subbed!
Being an audio engineer myself, this video was pretty spot on!
In the optical microphone, the vibrating diaphragm and the sensor can be separated by great distances. Here are two examples:
After WWII, the United States opened a new embassy in Moscow, and the USSR presented our Ambassador with a gift: a hand carved and painted copy of the Great Seal of the United States, to hang on the wall behind the Ambassador’s desk. Hidden in a cavity on the rear of the seal was a metal reed which would reflect microwaves (stretching the definition of “optical” a bit). Across the street behind the Ambassador’s back, the Soviets aimed a focused beam of microwaves at the reed, and detected the changes in frequency (the Doppler shift) of the echo, changing them into an audio readout of the conversations in the Ambassador’s office. Despite suspicions, many thorough bug sweeps failed to detect the spy seal for many years.
Incidentally, this device was designed by Leo Theremin, the Russian immigrant who invented the Theremin musical instrument decades earlier in the US, and was forced by Stalin to help him spy on the US after he returned home.
Today, a form of spycraft known to all spies is to aim a laser at a window and process the reflections into audio. A similar concept could be used as a remote seismometer to detect moonquakes by aiming at the retro reflectors placed on the moon by Apollo astronauts. Or to detect tsunamis from satellites by reflecting laser beams off the ocean surface.
Outstanding quality! It's a lot of information to digest, but very well packed and connected trogether. Thanks!
You and your channel are the absolute best! Great topics, and even greater explanations slash presentations!
These videos are amazing. Just found your channel today and have been binging everything!
terrific, as always
So glad this channel exists!
It's really cool that you fit it into the context of complete human history!
Diagrams were on point!! Great stuff man I love your channel.
Great content ! Can't wait for part 2.
Top quality content! Thank you
This is spot on!
Cool videos. I could type the same response on like all of them and give you the thumbs up lol. Seriously though, I really like your videos - they are well made and informative and I like how you get into quick side discussions of facts and history that better explain the thing main you're talking about while giving more context to understand.
Most of this stuff is already known to me, but I def learn some stuff with each video I watch. Keep it up man, seriously great stuff!
Fascinating, thank you!
Very high quality content!
Nicely done.
You have explained so much more to me in five minutes than my entire intro to electronics class has in an entire semester.
Thanks for the awesome content! I think this may be my favorite video yet, but I am an amateur audio nerd so that would make sense! 😊
A very good intro to the subject
Very good documentary!
I'm angry at RUclips for not showing me this earlier. I get all kind of nonsense in my feed but god forbid putting some quality content in there.
Anyway, great videos, well done!
Thank you. I agree! What’s blows my mind is that I don’t even get my own videos on my personal account feed sometimes. Go figure.
Good job. Impressive video
Great video.
very informative I appreciate your work
This is fantastic! I must ask though, what is your process for coming up with these scripts?
This is an excellent video.
Electrostatic loudspeakers are amazing!
Lovely..so much info in one video...👌👌
can't believe you left music boxes off this list; probably the earliest form of music storage.....
lots of information in an understandable dialog.
Great stuff!
Sub'ed.
More playlists please, for long-form subject watching/listening.
Thanks! Happy new year.
How much time does it take to make these videos
Beacause they’re really good

You skipped over magnetic wire recording which was replaced by magnet tape in the 1950s when it was invented by BASF, I have several working magnetic wire recorders in my collections
This channel is severely underrated.
this is very well made. i show this to my students now. roll tape...
I think this video is absolutely great... really really love it, and I can't wait to see the second part... but you forgot to explain what Signal-to-Noise ratio is... and I hope in the next video you will explain in-depth how DAC and ADC work... cause that's really interesting in my opinion...
Anyway, really good job!
Please go into depth over the divergence of digital signal processors and general purpose processors :-)
I truly believe that your videos are at the treshold of information density. 😁
Fascinating
The average groove-width my new favorite phrase
While this is very comprehensive and well done, I feel like this video should have a different title. Info about music storage stops after explaining magnetic tape and becomes an explanation of audio signals processing. I didn’t end up learning what I came to this video for.
Looks like we went way right in the explanation of Music STORAGE. Good info on range explanation but not storage of music to create playback.
Learning what music is, the engineering way.
I was a little disappointed that there was no mention of the Fletcher-Munson Equal-loudness Contour: en.wikipedia.org/wiki/Equal-loudness_contour
Aside from that (admittedly minor) omission, this presentation was nigh perfect. Well done, New Mind.
@3:40 - actually ALL of them convert motion into voltage, including resistive one which convert voice to the proportional voltage dropping on a resistor(graphite powder).
Magnetic recording with enough quality to be used for broadcast audio was perfected by the Germans and was not brought to the US until the end of WWII. The late 1940s is when magnetic sound recording really took off when the German technology was further perfected and manufactured by companies such as Ampex. Crown and Magnecord were also early manufacturers of audio tape machines.
thanks
Are you friend/relative with coreteks channel ? both very high quality of videos, a bit the same style, I recognized some musics used on both channels, and some topics discussed are similar
This channels going to bloom soon
I don't understand 48k views. Sub over here well done 😁
Sleeping why? :D again great video can wait for the next parts
Ayyyyye!!!!
Great summary! Not 100% accurate, but very good!
1:34 that's some creepy shit
Is there a way to estimate the effective dynamic range of a Phonautograph type recording medium?
The _OTARI MTR 90_ seen at 5:35 is a 24 track 2" tape recorder.
Not always. They originally came with a 16 track head stack. The 24 track stack was later introduced as an upgrade module and was part of the mkII rerelease.
I saw an Pioneer SA7700 in the vid. Fabulous amp. I have a SA7800, had since 1979 I believe. Such a nice amp .. lost a channel a few times but have always had it repaired. The surround sound amps now (and for past 20 years or so) are just awful. Over complicated, button heavy, spintronic volume knobbed (non pot) ... as in totally useless to me. Nice vids NM .. well done.
Just 30s into the video, the background of the video made all the reasons to watch until the end.
TFW tape is actually really good music storage medium, we don't remember that because all modern tape mechanism, reading head, electronics and tape itself is lowest of low quality.
You mentioned "Indonesian island of Borneo"... are u referring to an island of Indonesia, located near Borneo? Or are u referring to Borneo island?
Boneo, is politically divided among three countries: Malaysia (Sarawak and Sabah) and Brunei in the north, and Indonesia (Kalimantan) to the south.
great video!
weird title choice tho, a more general title would be suitable
Very interesting though the monotone metronomic nature of the commentary is hard to follow. A bit of breathing space goes a long way.
Wanted to subscribe when I watched the video.. but found that I already did some time agi. 😁
fucking underrated channel
This entire channel is like "shit naota3k wants to learn about". Madness.
Hey, man. The auto generated caption/subtitle of this video is somehow in Dutch. Can you change or fix it, please? Thanks before.
edit: There's also a problem on the 'The Evolution Of CPU Processing Power Part 3: The Origin Of Modern Operating Systems' video, the autogenerated caption there is unavailable.
Very underrated channel. Improvement tip: you are all over the place with your topic, its what didnt let me write essays in school, maybe try to talk about less things but explain them more. I really like your channel bit its sometimes hard to keep pace because you change the topics so often. Just my opinion🤷♂️
I never got how an animal can percieve anything lower than maybe 10hz as sound. Playing with electrical oscillators connected to speakers, I've found that once sound gets below this point, I can still "hear" it, but I only hear it as a series of clicks, where each click corresponds to one cycle. Ie 10hz makes the sound of 10 clicks per second. Rather than a continuous tone.
Although, I always used square waves, which are full of higher frequency harmonics, so maybe that's what I'm hearing, and the clicking is just these harmonics being modulated at the fundamental frequency. I'd like to try this with a pure sine wave, but I haven't gotten around to buying or making a device that can produce sine wave tones. Short of a mobile phone app, but I have doubts about the quality of such apps.
Plus, I'm pretty sure the relatively low quality speakers I use when fiddling with electronics don't have a very good response at 10hz, cuz why would a speaker need to be designed to function at frequencies lower than we can hear?
Borneo is shared by three countries: Malaysia, Brunei and Indonesia.

A video on how magnetic fluid works
Some details are not quite right without context. Yes, 140 dB is the absolute maximum dynamic range of human hearing but at 140 dBSPL your eardrums are close to bursting and you are well above the threshold of pain. Also your hearing needs time to adjust and you never get the full range at once. More in the ballpark of 70 to 80 dB at one specific level. Wich so happens is the effective range of CDs. Yes, I know, redbook standard is roughly 96dB of dynamic range on paper but assumes uniform distribution of the PCM samples, which music or speech or basically anything human made never has.
Quite the in-depth documentary into the history of audio representation.
Years ago, I attempted an "audio restoration" of the 1888 recording of Handel's "Israel In Egypt" made at London's Crystal Palace.
I believe since I only spent a week on it, I improved it maybe 60%-ish.

Thank you dude i appreciate all the work you put in making this very super duper informative though i would suggest you to define a few terms as not all people are familiar with the technical jargon
So he made his Fart be the first recorded thing.

wow, we can actually record sounds on soot.
You can record sound onto any visual medium that can be permanently documented, the issue then becomes playback. The sound recording you are referencing was unheard for over 100 years until the invention of computer image scanning.
what about magnetic wire recording? it predates magnetic tape by 30 years
Hey, I just watched hit romantic comedy Yes Man staring Jim Carrey
Mr. Watson - come here - I want to see you
ohw, this video is sooo old, i wonder how.... oh, okay. next suggested video.
Ahhh the good old days when we only had 2 ears instead of these millenials with at least 5.1 ears 😁
you did some good research to find all those lovely old pics of real stereo gear
Using a linear scale to show frequency response is silly.
Mega Interesting! UKRAINE with You
Now do a video on how the myth was debunked that analog vinyl records have better fidelity than digital - then I'll consider you an expert.
And you think he cares for your opinion on his expertise?
hehe
