how is digital sound created?


So sound is a vibration which is created from things rubbing or banging together etc. If stuff isn't interacting with something to create a sound how are sounds created from nothing? I.e in the digital world? Music on an iPod or a beep from a computer? I have always wondered what the noise's are and that come from computers when they are 'thinking' or working - wtf's going on there?

What happened to the ones and zeros, or the on and offs?

I mean digital, digital.

What we hear is analog right? How it's transmitted received and then reproduced is the difference. There is no conversion just amplification, and transmission in the analog world.

There is a program running in the digital world using a processor to convert the 1s and 0s. I thought they were RISC-V or ARM Based too.. Cirrus chips are risc based. They are better known for numeric processing or as a math co-processor. Mac chips were risc based,

Intel and AMD chips used and extended or SISC. 8086 is still close to the speed in the real world..

R-2R ladder  and  combinations or hybrid DAC tech seems to be the direction its all doing to me.. No single DAC Tech seems to be able to do it all.. Multi types of DAC chips in the same enclosure is closing the gap between Analog and Digital.. I'm just amazed at the progress and SQ refinement over the last 10 years. Look at STL

The problem is RISC-V is open source it's NOT proprietary. The competition would be a government (like China) vs a company like Intel or AMD. Who has the motivation and what's the reason for the Tech advancement.. 

A DAC is used in Stealth Tech, Sonar, Radar. It's a real world military device, I'm sure that is what it was developed for..

Open code... I don't think it's gonna fly over the long term or gain a public market knitch. The military has the resources the Audiophile world doesn't.

pick your so called expert carefully…a moving magnet microphone would suck… Care to study things again Albert ?

Sampling is just the beginning. 
Funny how some analog zealots have not so much trouble listening to digital files run back thru lossy homogenizer tape decks… to wit Famous Blue Raincoat. 
If the OP means electronic music or sounds, then I suggest looking up the history of digital synthesizers and FM synthesis.

At its most basic, sound (and music) can be modeled as the sum of sine waves of different amplitudes and frequencies. This is the most important concept to understand and underpins all of digital audio. Here are some links that you’ll hopefully find useful:
