I love DSD because of it's pseudo analog qualities. You can even attach a audio line in straight to the bitstream output, and you will hear music.

@PimpinBassie2, DSD is that magic signal that can be picked up as analogue or digital. It does away the need to know byte size, bit alignment, signed/unsigned, CRC (checksums/parity/redundancy bits).

According to the Nyquist-Shannon theorem, as long as the sampling rate is at least twice the frequency of the signal, then you will have a lossless representation of the signal. That is why you won't hear any difference above 44.1Khz sampling rate because 44.1Khz is more than twice the sampling rate of the highest possible frequency (20Khz) we as humans can possibly hear.

True. And engineering is awesome for knowing such things. Still the curious mind wants to observe, we want to observe and see if there is a perceivable difference in these waveforms.... I giggle at it. I'm an engineer and have audiophile friends and enjoy the topics. But the masses decided for us when we started downloading and streaming lossy codecs and listening on lo fi systems like earbuds and bt speakers.... Convenience won over fidelity and that was obvious..... So these topics are left to us nerds as a purely intellectual pursuit.

If there’s an audible difference between redbook and DSD (I can’t hear it with my mid-range dac/amp/headphones), it’s very small compared to the impact of the recording, mastering, amplification and playback (speakers or headphones). As storage and processing of large music files is now a non-issue, I’m not averse collecting them, but I won’t be paying a premium. In my case much better to put that money into a better set of headphones.

Do the math. Every bit of depth cuts the signal level in half. If you think of a 2V line level sgnal, 2 bits would give a 1V resolution between steps. 3 bits .5V. 24 bit would require resolving roughly 0.00012V per step. Technically impossible today. 20 bit is about today's limit. Sampling rate is far more important than bit depth.

Well then theres sook much more then the bit depth of audio, so if the audio is 16bit, then we need to also what’s the amount of khz,then we also need to know the amount of kilobytes per second and we also do need to know the S/N to noise ratio ,, so for instance an 8bit sample at 4khz can be sounding just as bad as a 4bit sample at 16khz,or a wave file at 128kbps can be sounding not any better then an mp3 file at 320kbps,,so all these examples shows then this makes no sense at all ,same thing with a micro processor,, an 8bit cpu running at 12mhz can be equal to a 16bit cpu running at only 3mhz,again making no sense.

Sure the original DSD rate was 2.8MHz, but there are multiple implementations, which most DSD DACs have. DSD512 is 24MHz. As far as I understand it, that's the general idea of how DSD works, which parts of it are very inaccurate?
@raptorep6 жыл бұрын
Lior, it's not so much as inaccurate as simplified. DSD is hyper precise and is, at it's core, dumping the raw signal from the AD/DAC into a wrapper. Hardware recorders can set the DAC to the right frequency to the DSD depth you select that's why it's not really a consumer format. You need hardware that operates differently then the set rate PCM DACs, much of what PCM recording does is in software, hense cheaper then the variable frequency DACs used for DSD.

You don't get a "sharper" signal if you sample at lower sample rate. This video explains it really well kzfaq.info/get/bejne/ma-BbKyJuLvepYE.html. It is also called the Nyquist-Shannon sampling theorem. You do lose some precision after quantizing, that is, changing the values from the y axis to the available ones.

Basically this entire argument boils down to what algorithm is good enough. Since almost all high end audio formats are in PCM, and studios/people have a lot of money tied up in PCM, the likely hood of DSD or DXD gaining in mainstream popularity is close to nil. In my view PCM is just fine, and DSD/DXD is just diminishing returns.
@superescalar7 жыл бұрын
DXD is PCM, but 24-bit 352.8KHz studio format. But dsd is marketing. There are almost no pure DSD recordings available to consumers. This is because there is currently no way to edit, mix, and master DSD files. Only the rare DSD recordings made from a mixed and mastered analog recording, or those recorded direct to DSD without any postproduction, are pure DSD. Most so-called pure DSD recordings are, in fact, edited in PCM. Most commercially available DSD recordings have to be converted back and forth to a PCM format in order to do postproduction editing, mixing, and mastering. In each of these conversions, more quantization noise and/or quantization errors are added to the recording. This leads many to ask: why degrade performance by adding the additional step to convert to DSD when the master is already in PCM?. DSD has significantly higher quantization noise than PCM, and the noise is much closer to audible frequencies, requiring significantly more sophisticated digital filters, as well as noise-shaping and upsampling algorithms, that can result in distortion of the analog signal. When a PCM file is played on a DSD or Bit Stream converter, the DAC chip has to convert the PCM to DSD in real time. This is one of the major reasons people claim DSD sounds better than PCM, when in fact, it is just that the chip in most modern single-bit DACs do a poor job of decoding PCM. Another issue is 96KHz and 192KHz HD audio. Though modern sampling rates are high enough to fool the human ear, quantization errors still occur when translating from one format to another. For example, when Sony decided to archive their analog master libraries to DSD64 back in the mid 1990s, they were wrong to believe that these masters would be future-proof and able to reproduce any consumer format. The fact is, these masters could only properly reproduce a format that was divisible by 44.1KHz. So any modern 96KHz or 192KHz recording created from DSD64 master files have quantization errors. This leads me to one of the many things that enrage me about the recorded entertainment industry. If 44.1KHz was the standard that was engineered to put aliasing errors in less critical audio frequencies, then why did they start using multiples of 48KHz?!?!?!? All they had to do was go with 88.2KHz and 176.4KHz as the modern HD consumer formats, and all of this mess could have been avoided. The same thing happens with DXD (24-bit 352.8KHz) equally divisible by 44.1KHz. What blithering idiot decided to put a wrench in the works with 96KHz and 192KHz HD audio?

@raptorep6 жыл бұрын
I see DSD as a Mastering and Archiving format, even PCM 192khz 24bit converted to DSD gives the PCM enhanced depth, being able to distinctly identify specific instruments that was muddied when in PCM. DSD is also coming back with the Audiophile scene and you can buy new 2017/2018 built recorders and even the old professional recorders are keeping value. What became obsolete is SACD, what survived is DSD and expanded upon with DXD to get even more from the format. What people don't understand is DSD is basically a wrapper of the RAW signal before the A/DAC samples it. So your getting basically a direct digital conversion from analogue which retains nearly all of analogue's unique characteristics, like the high frequency noise, which is above 20khz and out of the hearing range of 99% of the population btw. Jay did good on the basics, but his perspective in more of the every day user, if he explores more into DSD he'll have a better overall perspective.

Çerastes is correct. Whether sampling 1 bit at a time or 24, the end result is the same: an output that's practically the same as the input. 1+1+1+1... or 1+2+4+8 is of no consequence since the sum will be the same in both cases. If the sum is different, it's a design error, not some "quality" of one or the other methods of addition.
@raptorep6 жыл бұрын
The difference is precision and sound stage, DSD is far from obsolete, there's almost zero quality loss from the actual source, whether from a microphone or vinyl. There's a perceptional difference between instruments and dynamic range. If you listen to reference level headphones or speakers it's very noticeable. Less so on KZfaq because the transcoders degrades it heavily. Get Foobar2000 with the DSD plugin and download an actual dsf or dsd file and i'll guarantee you can hear the difference. Unless you actually hear it and compare it you don't understand it nor qualified to brush it off.
@StringerNews16 жыл бұрын
Let's be fair now. Precision is a thing, and a thing that I am familiar with. It's just that saying "precision" unconditionally has no meaning in itself. James, what parameters are you claiming DSD is more precise with? What is the difference in precision, and why is it significant? Please be specific. Precisely what "quality" are you claiming that DSD doesn't lose? How does LPCM lose the same quality, and why? Which "actual source" are you referring to? You never defined any of those! I do hope you aren't claiming that DSD bits are hand-made and "artisanal". BTW, what is your reference level? As for your entreaty to install software and listen to things download, no thanks. You may not know this, but computers inherently use the same type of data structures as LPCM does. If that's how you've been listening to "DSD" then you've been fooled; all this time you've been experiencing the superior precision, sound stage and quality of LPCM. If you have an all-serial signal chain to lend, I'd be happy to make an apples-to-apples comparison.

Çerastes, I recommend You following experience - very good turntable with good tonearm, very good moving coil low output cartridge, step up transformer and good phono stage. Now let's make vinyl rip with digital recorder KORG MR-1000 to 1 bit 5,6MHz dsf file (PDM DSD). This file can be 3-5 GB big. Later make PCM 16bit 44,1kHz rip flac or wav file with the same or similar digital recorder like Korg, Tascam. File will be much smaller 300-500MB max. Later compare both files on very good hi fi/hi end systems. Difference is HUGE. DSD is the best technology to digitalize analog sound sources. For instance sound of violin is different, sound of man's voices, percussion, cymbals etc. Try to do it. Best regards from Poland.
