What I DSD?

[Woahduds]

I know it stands for direct stream digital and use for dac. How it is different from normal DAC

DSD uses pulse-density modulation encoding—a technology to store audio signals on digital storage media that are used for the SACD. The signal is stored as delta-sigma modulated digital audio; a sequence of single-bit values at a sampling rate of 2.8224 MHz (64 times the CD Audio sampling rate of 44.1 kHz, but only at 1⁄32768 of its 16-bit resolution). Noise shaping occurs by use of the 64-times oversampled signal to reduce noise/distortion caused by the inaccuracy of quantization of the audio signal to a single bit. Therefore it is a topic of discussion whether it is possible to eliminate distortion in one-bit Sigma-Delta conversion.[1]

Will it make a difference in sound quality at all?

Who cares? Like 1% of music is available on DSD.

oh i didnt know that, that thought it was just a way to decode it

No, it's an audio file format, pulse-density modulation (PDM).

 

Most audio is stored as pulse-code modulation (PCM), although ironically it is converted to PDM in most DACs before the analog stage.
