"Native editing" (without conversion to multibit and DSD re-modulation) is possible for cutting and merging DSD records only.Īll other kinds of editing demand conversion to multi-bit values and re-modulation. dsf (DSD audio files) here:ĭSD editing is cutting, merging, gain altering, equalizing, etc. Read details >Īlso read: DSD player F.A.Q., DSD converter F.A.Q., Myths Upsampling can optimize audio file resolution to optimal (minimal playback distortions) for your equipment. Sound is defined by record quality, your playback program and apparatus. Hybrid SACD also may contain CD layer compatible with usual CD player. Read details.ġ minute of DSD64 stereo is about 40 Mbytes. Recording, certain equipment makes sound quality. Theoretically, DSD has better potential than FLAC and other PCM formats.

It depends on record quality, your software and equipment. There is no unambiguous answer to the question. General answer: "Each case is individual and depend on playback system implementation and listened to record".ĭSD sound quality and other Are DSD downloads worth it? Are DSD files better? Even as single DSD/PCM compatible DAC is used for the test, the difference may be caused by different mixing/post-production of records, and the DAC uses the different circuits (see here). Technically, DSD and PCM are incomparable. These reasons trigger infinite discussions "what is better PCM or DSD". Playback software/hardware implementation Mixing/re-mixing of the record (including quality of the processing) But the difference here is band reserve for pushed noise out of audible frequency range.

Read which is better DSD or FLAC (Infographic) >ĭirect Stream Digital (sigma-delta modulation) is like to pulse code modulation, but quantization error spectrum is shaped for decreasing noise into the audible range. Note: WAV and FLAC are PCM implementations. Read details of the format comparison in the table: DSD vs WAV vs PCM vs FLAC vs DXD Fea tureįile, digital tape, optical disk: CD, DVD Other words, if we want to reduce bit depth, we must increase the sample rate to keep the audible noise level.

More bit depth is lesser noise.Īt the picture, we can see that bit depth decreasing achieved through using only part of the full signal frequency band. Ultrasound noise can cause audible intermodulations distortions.īit depth define audible noise. But the noise should be maximally suppressed out of the band. Noise level in the audible frequency band almost don't depend on demodulator. 145 dB (comparable with PCM 24 bit)ĭ128 about -165 dB (better than pulse code modulation 24 bit)ĭ256 and higher about -170. Pro audio modulators have noise level in audible frequency range for sample rates (read details):ĭ64 about -125. But, on the other hand, we can increase the sample rate and/or bit depth to decrease error level for the same NS method. We can see that lower noise and higher stability to overload can be achieved in different ways.Īs an example, better quality is noise shaping implementation matter for the same bit depth and sample rate. It allows reducing noise shaping steepness, that increase overload tolerance of the modulator. Higher sample rate allows reducing the noise level in audible frequency range. But figure, that more expanded in the horizontal axis, give lesser noise level. Noise shaping (NS) of 1-bit signal (spectrum)Īt the left and right pictures, squares of the noise energy figures are same. And quantization-error energy is re-distributed. However, there is, so-called noise shaping of the spectrum is used. To decrease noise level, noise shaping is used.ġ-bit quantization-error (noise) energy has a significant level. There is an explanation, that DSD has super high sample rate and, thus, super low bit depth 1-bit does not matter for noise.īut DSD 64 sampling rate (2,8 MHz = 44.1 kHz * 64), it is not enough to be better CD audio (see details). To estimate DSD and PCM sound quality, the quantization-noise level is main criteria.

Instead the explanation, in the author's opinion, the easiest way to understand how to DSD works and process it is its spectrum consideration. About the processing read below in "DSD editing software" part. Probably, it creates myth about "native" DSD processing. Such explanation causes difficulties in understanding what is actual difference between PCM and DSD and how to process DSD. And measuring signal grows until the exceeding of the input signal. When the measuring signal level is a lesser input signal of the ADC, its output is switched to "1". And measuring signal begin to reduce level. It causes the output signal switching to "0". And measuring-signal level grows until it exceed current level of the input analog signal.
