Please Educate Me


If I can’t find the answer here, I won’t find it anywhere. 

Something I’ve wondered about for a long time: The whole world is digital. Some huge percentage of our lives consists of ones and zeros. 

And with the exception of hi-fi, I don’t know of a single instance in which all of this digitalia isn’t yes/no, black/white, it works or it doesn’t. No one says, “Man, Microsoft Word works great on this machine,” or “The reds in that copy of Grand Theft Auto are a tad bright.” The very nature of digital information precludes such questions. 

Not so when it comes to hi-fi. I’m extremely skeptical about much that goes on in high end audio but I’ve obviously heard the difference among digital sources. Just because something is on CD or 92/156 FLAC doesn’t mean that it’s going to sound the same on different players or streamers. 

Conceptually, logically, I don’t know why it doesn’t. I know about audiophile-type concerns like timing and flutter. But those don’t get to the underlying science of my question. 

I feel like I’m asking about ABCs but I was held back in kindergarten and the computerized world isn’t doing me any favors. Now, if you’ll excuse me, I have some work to do. I’ll be using Photoshop and I’ve got it dialed in just right.

«Always face your wife if asking a question»-Groucho Marx

@mahgister....I’ve done that...it’s almost as dangerous as not...*L
Facing your wife was not recommended in this aphorism to give a better lie, it was recommend because she will spot you with a bad lie on the spot and it will be easier for her to forgive you..... 😉
I never lied to my wife more than 5 seconds....

All wives are also mothers and they will forget about your " bad" lies like they forgive children...

But if you think you are a "good" liar, and dont even need to face her, you are already dead before the first lie... 😁

Could be that some of us are put off by you requesting us to educate you (do the work for you) rather than you investigating for yourself like most of us have done.

High level: sound/music is an analog continuous waveform while digital is 1 and zeros. The analog is converted into digital (1 and zeros) then back to analog before playback. The amount of digital file resolution can be hi (like SACD) which contains more information than a lower resolution file (MP3) and sounds significantly better on a good resolving audio system. Also, the digital stream may be affected by outside influences which can be heard audibly. Jitter is the time distortions of recording/playback of a digital audio signal - try Googling. Also, there are several technologies for DACs (Digital to Analog Converter). Finally, our audio acuity is much more complex than the current science can define.

Bottom line: it’s not just ones and zeros aka yes/no, it’s how well executed the analog to digital back to analog is accomplished.

search within his videos for several seminal discussions of analog vs digital music production and fidelity, and how to make digital sound right
I left another forum because people were just as rude. Always online never in person. 
Music is analog consisting of sound waves.

Amplifiers and speakers also operate in the analog domain using electric signals that vary in intensity over time....not just two values strung together to create other values which is what happens in digital domain.

Sources can be digital and reside on computers but the digital information has to be converted to analog to make music.

To do that the digital electric signal must accurately represent the digital information at the source and then be converted to analog. Time is a key component of music so the D to A process has to get the time dimension of the analog signal created from the digital one right or in other words produce the right information at the right time.


You can see that is a complex and sensitive task and results can vary widely. Music waveforms are analog, complex and hard to represent accurately especially at higher frequencies.

Any program that resides on a digital computer must convert to analog at some point in order for a human to interact with it.

What is displayed on your computer monitor is also a result of Digital to analog conversion but a different kind. Here the digital signal is converted to light intensities and color using pixels on a computer monitor and what you see (which can also vary) is the result of that digital to analog conversion process. 

Same thing happens with a HDTV. 

So the bits on the computer in digital domain are always carefully preserved Else the programs would not work But it’s the conversion from digital to analog where results can vary widely.

Hope that helps.
