Its better explained as re-timed. The data is received at a baud rate determined by the signal source clock. To use the data you have to clock it in at exactly (+/- buffer depth) the same rate. The receive clock needs to match. We use a phase-locked-loop, which can alter the receiving clock frequency to match the incoming data. Dependant on the phase difference of the data. This way a one is always clocked when it is secure at a one level, and a zero under the same condition. If the clocks drift too much you will encounter the transition and it’s a coin-flip on an error. The quality is down to the phase-locked-loop. The worst is digital “bang-bang” phase detection, I prefer analogue with a VCXO (voltage-controlled crystal oscillator). This said the digital PLL are now good enough to be indistinguishable. The issue with most PLL is that when the clock is slow, the electronic circuit senses the phase error and speeds up the clock, same for when the clock is too slow. The question is when the clocks match, because there is then no phase mis-match, and therefore no error signal from the phase detector, the clocks will eventuality drift until correction kicks in again. This is called wander. For data edge detection PLL, if you get long strings of ones or zeros, then the clocks again can wander. It matters in digital systems, but not audio. PLL Jitter is a whole subject.

This is a crappy solution due to messy architecture. Much better is to run the DAC clock precisely without PLL and the data flow from source (AWS data center, for example) to DAC is entirely asynchronous. Audio data through the internet and USB can support this while SPDIF, TOSLink and I2S are synchronous and creates problems with multiple clocks and jitter. Why the heck not get this issue correctly fixed???

@@davidfairchild1640 I listened to this video again and had I been an engineer at PS Audio I would have gone to Paul and said, why don't we fix this entire multi clock master mess and make our product family run asynchronous data completely eliminating this entire topic? I can understand this crap of multiple clock masters exist due to legacy solutions, but come on, Paul has an in-house R&D team that can do better. And even I2S can pull data asynchronously at a rate determined by the DAC, if that was an issue. A CD transport and streamer with asynchronous I2S output (pulling data via DAC clock as master) and a DAC with I2S asynchronous input (serving as PLL free precision clock master) would be something...

It seems that anything coming through the Knternet comes in data blocks. A burst of so many KBytes from one path and another through another. The receiver has to arrange them in the proper sequence but that came in with unrelated or no real clock. So the finalbdelivery of the data streem must create it.

Interesting. I would have thought the optimal approach would be to have all of the DAC recloaking functions described, but also to have an I2S input that does not reclock so that you have the option to use an external clock of better quality than the DAC. I also like having the clock section with the option to replace the clock so that you can experience different clocks as you might change tubes. Typically this degree of flexibility comes with ridiculous price tags commercially, so it is a perfect area for DIY.

@@Pete.across.the.street Agreed. I have done all the above with good results. I have soldered the tiny little NDK SDA clocks that require a steady hand and a magnifying glass. My current end game setup has the clock in a separate well insulated/dampened chassis with it's own power supply. It is connected via a very good 1m coax terminated with SMA connectors. I can also disconnect that system and pop in any of the 5V 4 pin clocks. The key is to have a SOTA low phase noise clock at it's optimal temperature in a vibration dampened enclosure. Power supply matters but not as much as vibration control.

One question is, does the reclocking in the DAC, which I presume has not the same quality as the Air Lens, the signal worse, or does it make the signal even better? I would think that a reclocking would bring the signal to the quality level of the reclocker, so if the incoming signal has better timing, the signal could be worse after the reclocking. But this must not be the case, because that would make the reclocking in the Air Lens useless.
@user-od9iz9cv1w

If you do not have the option in the DAC to bypass it's built in reclock/timing then you are always listening to the jitter of that system. An Airlens type of device will make a small difference solely by adding one more galvanic isolation. It's reclocking function is just a waste of parts/money.

Clocking, reclocking… actually a completely waste of time and resources. The format of data is well defined. The DAC knows the number of bits per second to be converted and so the only place for a good clock is the DAC. Delivery to DAC is best when it is implemented asynchronous and the bits are stored in big buffers on DAC side (e.g. 10 Mbyte would be good in order to deliver interrupt free music). It’s time for a paradigm change: computer scientist should take over from the “engineers” the architecture of digital music delivery as it could be implemented perfectly without all this “reclocking things” in between the file and the DAC… just my 2 cents.

No it didn't answer it but I will... No reclock is perfect. Having a digital stream clocked a few times usually leads to a better output signal and does sound better. However, there is a trade off. To reclock you must use a buffer. Using a buffer increases latency. More reclocks = bigger buffer = higher latency. Not the latency effect of waiting for music to play or drop outs, but latency of streamed audio has a big effect on the time domain of playback and helps, when u have ultra low latency networks, create a better sense of space, soundstage, instrument placement ect. As everything, there is a balance here. Multiple clocks before a final clock SHOULD NOT affect ANYTHING. However the sonic differences are absolutely undeniable I can show this clear as day with recordings I took. I used to think the last clock is all that mattered... False. Remember we don't understand everything and we commonly think X and then find out later we were wrong. Don't fall into the camp it can't make a difference because that's not what we "know is right." Just like medicine, what we are taught, common saying is 50% will be wrong in 10 years (I am in medicine)

Complete and utter horse crap. Only the final clocking matters. A clock latter on in the chain completely replaces any previous one. That's assuming the signal even had a clock at all. A USB audio signal doesn't carry any clock information. Also latency has 0 effect on sound quality and only matters when accompanying a video. Latency could be nanoseconds or several hours and it's not gonna sound different.

Nah, I think you have been lied to. The only things that matters is if the last buffer is of adequate size, has a proper data feed, and has a high quality clock on the output. All the buffers before it don't matter. In fact if you really want to be picky, you could say that having a couple buffers and reclocks before the last stage would be beneficial because you can better control overflow and underflow conditions.
