Finally an easy to understand explanation that made sense. Thank you.

I never understood how we convert images and sounds into something packed inside a disc. Today i know. And i just feel a little more enlightened. Thank you so much. I wish to get more videos from you coz i am inherently, miserable in understanding technology.

Here is one of the most awesome human being I have had to pleasure of stumbling on and listening to. He uses simple straight forward no bullshit words to describe what is going on. I wish I had him as my teacher back ... way back in the days. I would have graduated. Instead I got lost with the 0s and 1s they chocked me with and had no idea what was behind it. So the amplitude which is an analogue rising or fallling values is represented not just by two values of voltage ( 0 and 1) at its peak but by many bits to represent various values of voltage at that point. The higher the voltage to bigger the number that 0s and 1s represent. So a 10V rise has more 0s and 1s than a 1V rise, etc. I am hoping I got what he is saying.

This was a fantastic explanation. Thank you so much! Very underrated channel. I think if you upped the sound /video quality it would help greatly. Thanks again!

I have a question, why is it oscillating in the illustration around what seems to be the middle of the bit range? Is it actually a signed range and that's the 0 value? Or is it just.. some sort of tradition? Why does every wave making program have an "above" and "below" part to a wave shape?

sir ,If we create a drum like thing and that beats 44100 times every second, would it be silent if it passes through the mic,adc and dac ?? If it starts its first beat in between the sample interval??

I didn’t get actually how it convert sound in 0 and 1 as 16 bits mentioned to recognise words and colours but how sound wave converted into 16 bit binary?

One thing that confuses me and maybe someone will have an answer, even though we're sampling once per 1/14k second, we're still only sampling one data point for that slice of time. How does this work for harmonies, complex notes, or overlapping instruments. If the music is playing a bass and treble sound at the same time, how are both of these sounds being managed by an individual data point? Does it alternate? Does it average the two?

@schizo7195 Жыл бұрын

From what I understand when these both sounds are played they'd still come off as a combination of both like the waves have both their sounds so what the computer does is sample the instaneous amptitude of each note of that exact sampling note. so when representing them as a chord they're played back to back and when it does our ears can percieve it as a harmonic blend it is. Now the accuracy of this representation as said in the video depends on the bit depths and higher sampling rate and a smaller distance between each interval. I hope this helps!
