![]() ![]() If you transcribe a DVD recording to 192/24 there has not been any actual theoretical loss due to the 192/24 digital format. The big idea you need to understand is that from a theoretical dynamic range standpoint, 24 bit PCM walks all over DSD. Now from a listening standpoint this is all very good performance, and gross overkill. ![]() Above 20 KHz or so, the noise floor is allowed to rise significantly to as little as 50 or 60 dB. DSD has a higher noise floor below 20 KHz, which most authorities put in the range of about 120 dB. 24/192 has a theoretical dynamic range of 144 KHz from full use of the 24 bits with a low uniform low noise floor up to 96 KHz. I'm sure that there are some from the lunatic fringe who would fight to the death for those 4 KHz above 96 KHz, but they are lunatics, right? -) So, this minuscule HF band pass difference is a draw in the minds of everyone with a mind. ) Trust me, not even the most enthusiastic technically credible advocates of high sample rates would argue that any veils at all are lifted by increasing HF band pass from 96 KHz to 100 KHz. I guess that DSD claims HF band pass to 100 KHz, while 24/192 has 4 KHz less band pass, only 96 KHz. Very little to vanishing, depending on how the recording was sourced. Quote from: Happy Water on 21:18:13 How much loss is there when we convert DSD to PCM(especially 176.4KHz 24bit, by foo_input_sacd Plugin or AudioGate) for playing those Albums which are claimed recorded and mixed under Pure DSD Environment? (if any?) So the data they sell you as 1-bit DSD may not be so PURE We have some people here with more insight here, just my thoughts.Įdit: And about PURE DSD production you should wonder who still uses 1-bit DSD ADCs when multi-bit DSD became the norm. To be on the safe side you may use 88.2kHz but everything above only wastes space with recreating huge amounts of noise that in reality better should be filtered out. Having some pre-ringing at 24kHz makes your music sound bad but 60dB more noise up there doesn´t. Just realize how they claim the advantage to have no ringing filter up there with DSD. At 24kHz the noise in DSD is already ~60dB higher as with PCM, no music up there you will miss imho. When converting 1bit DSD to PCM 20bit and 48kHz sampling rate may be already enough. So you see you can pretty nicely create the complete DSD signal in PCM, even with all the noise Software programs like Pyramix advertise to use 24bit/354.2kHz PCM as intermediate format for processing. The DSD files they offer may have been PCM before while they were mastered. The chances there is a loss isn´t that high. How much loss is there when we convert DSD to PCM(especially 176.4KHz 24bit, by foo_input_sacd Plugin or AudioGate) for playing those Albums which are claimed recorded and mixed under Pure DSD Environment? (if any?)īTW, I heard that only a few Music Albums are recorded under pure DSD environment while the others are converted from PCM tracks. However, there is still one question confuses me. Quote from: Happy Water on 21:18:13 Now I think this should be the key word for me as I do originally thought that Sony invented DSD for better sound. So it is not pointless in trying to play DSD on the PC. PC can provide us flexible interface, large storage space and lots of other conveniences. On the other hand, just like we rip CDs into PC. In one word, I'm trying to find out a theorically ideal device(no matter Soundcard or DAC). Even if there is not so much difference in sound quality that I can hear. That is why I turned to Devices that *REALLY* support DSD playing. ![]() <-Anyway, PCM does not have such a high sampling rate as DSD do, thus, we can never Cover(convert without any theorical losses) a DSD stream by a PCM stream. In theory, we need just a LPF to convert a DSD bit stream into an Analog Signal(however, to achieve a good sound quality, a good implementation is necessary).Īnd converting DSD into PCM will loss almost all the advantages of DSD(Base Band SNR, bitrate, etc.). I'm not sure what do you mean.But in my poor opinion, only a few Products perform such actions, so it doesn't matter a lot to the topic. "intermediate format" do you mean that some DACs prefer to convert PCM into Analog Signal by using delta-sigma modulation(or just like a Class D Amplifier)? You can get more or less the same effect using the PCM interface as the DSD one (at least assuming you have a high enough sampling rate). Quote from: saratoga on 00:34:59 Internally most DACs seem to prefer to work with DSD by first converting it to the same intermediate format as they do PCM audio, so I'm not sure theres any point in trying to play DSD on the PC.
