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. So, qualitative DSD and PCM system can bring us the same final result.

If our eye can't rersolve the figures, there is no difference squares or circles we are used. These figures may be significantly smaller of the assembled image. Above we discussed DSD vs PCM like mosaic from squares and circles.
