Why asynchronous audio should not have been removed....and an idea.

RF can still interfere with DC circuits. I mentioned that it was extremely unlikely.

You assume we have this condition because?

Kinkin has a habit of stating incorrect claims as answers. I have a habit of correcting him. That's true everywhere on these forums regardless of the subject matter.

Wally123 Wrote:to which I must say that when you use a standard 3.5mm headphone jack, that is analog...Analog works wonders with Synchronous audio because the sine waves vary in carrier signal. When we try using synchronous audio on digital...it cuts off the signal at certain peaks of the sign wave...and it's hard to balance that. Asynchronous audio in most cases allowed for two or more simultaneous streams of the same data.

Please, no more. That makes almost as little sense as your original post. I would correct you but I can't even figure out wtf you're trying to say here. It seems like you just mashed a bunch of random audio terms together that don't fit.

Wally123 Wrote:A DAC, as people know, is the Digital to Analog Converter...Any video card still using VGA cables requires a DAC for a proper display because the video signal is digital but must be displayed on an analog monitor.

Not sure why you felt the need to define a word that we have been using correctly for several pages now.

Also the display can still be digital in this scenario. DACs are needed when the interface is analog and the source is digital, regardless of what the receiving device uses internally.

Wally123 Wrote:Audio cards on PC's require a DAC circuit for people to use headphones. The benefit to this is that audio card manufacturers take advantage of this to get past the requirement that digital audio signals have time delays. Analog based audio devices have more tolerance for error than digital, but can be expensive to sheild it from (what little) interference the outside world provides.

Digital signals are far more tolerant of interference than analog. That's their main advantage over analog. So much so that unless something goes horribly wrong there won't be any errors in a digital interface period. Though it depends on distance and cable quality most analog and digital audio cables are either unshielded or shielded very cheaply. Audio cards don't provide digital interfaces to reduce time delays. They include it in case you want to use your own audio hardware without the additional signal noise of converting analog/digital back and forth multiple times. The main purpose of an audio card is to act as a DAC, ADC, and preamp. If you plan on using an external device to perform these functions there is no reason to use an analog interface and therefore no reason to have an audio card. All audio signals eventually need to be converted to analog. There is no other way to make sound from them. And almost all modern audio sources are digital.

Silver is more common and less expensive and is standard for most digital equipment..and copper wire with proper impedance and wire gauge work just fine to deliver signals...I love optical for consistency, but it is so consistent it often sound brassy to me (my Aspie super power is in hearing electrical faults...and trust me...I do get distracted by it lol)...

Even more incorrect assumptions.

The atoms in the cable don't move significantly more than any other comparable solid body. And they certainly don't move in one direction. I was thinking that perhaps you meant to say electrons but even that would be wrong since they just oscillate back and forth in this scenario.

Silver is not common in most digital circuits and cables. In most cases it would be extremely stupid to use. Again none of this makes any sense.
