DSD audio is a high-quality digital audio encoding method that uses a encoding method called "direct streaming digital". Compared with traditional PCM (Pulse Encoding Modulation) audio, DSD audio adopts a higher sampling rate and captures audio signals more accurately, thus providing higher audio quality and fidelity.
The sampling rate of DSD audio is usually 2.8MHz or multiples of 2.8MHz, which is 64 times higher than the 44.1KHz sampling rate of CD. The sampling accuracy of DSD audio is 1bit, which means it uses a very simple encoding method to convert the audio signal into a series of binary digital signals. This simple encoding method allows DSD audio to have higher dynamic range and lower distortion, thus providing better sound quality.
DSD audio is mainly used in the fields of music production and audio recording, and it can provide higher audio quality and fidelity than traditional PCM audio, so it is favored by many music lovers and professionals. However, since the encoding method of DSD audio is very different from that of PCM audio, a special decoder is required to decode it in order to restore the original audio signal.
What is the difference between D2P, DoP, and Native?
D2P: DSD is converted to PCM output, so what is actually output is the PCM signal;
DoP: DSD is output through the PCM channel, both DSD over PCM, and the actual output is still a DSD signal;
Native: The DSD signal does not pass any processing and is directly output natively, and the actual output is the DSD signal;
DSD specifications and sampling rate relationship?
DSD64 -> 2.8MHz
DSD128 -> 5.6MHz
DSD256 -> 11.2MHz
DSD512 -> 22.579MHz
DSD1024 -> 45.158MHz
Under what circumstances is the DSD output mode in HiBy’s music player adjustable?
Analog output (LO\PO\BAL\BAL LO and other analog output): The DSD option is invalid, and all three outputs are unified into the simulation support format of the device (for example, HiBy R3Pro is Native, HiBy R2 is DoP, please refer to the corresponding instructions for other models);
SPDIF digital output (coaxial, fiber optic): DSD (Native) and DoP are both unified into DoP, because SPDIF has no definition of DSD Native; (The options are still Native and DoP, but both DoP outputs are DoP. Because coaxial does not define Native. Keeping menu consistency is just the behavior of output DoP.)
USB output: If the connected USB device supports DSD (Native), then Native and DoP will both be effective; if the connected USB device does not support DSD (Native), then when choosing Native and DoP, both DoP will be unified;
Note that since the SPDIF coaxial output and USB output of the HiBy player both pass through the TypeC port, the user needs to confirm whether it is coaxial or USB output.
