As we all know the analog sound has limitless resolution but in digital world data is limited by the resolution of its digital representation. The lower resolution the less data can be passed to the digital-to-analog converter (DAC) for the accurate generation of analog sound.

Modern DACs are sophisticated devices which operate with 32-bit resolution and some oversampling DACs use 64-bit math to improve SNR even more. While in majority of cases these DACs accept 32-bit integer data which provides theoretical 192.66 dB SNR ratio there is still limitation imposed by the necessity to convert the floating point data of the audio engine to the integer output format of the DAC. This conversion is causing the quantization error when the audio data resolution has to be decreased, for example: audio engine operates with 64-bit resolution and we must output to the DAC in 32-bit integer format which requires truncation and effectively it is a source of the quantization error.

To lower quantization error within the perceivable range of the frequencies (for the human) we can employ the output in DSD format which is highly oversampled 1-bit digital representation of the audio data. Due to high oversampling ratio we do not truncate data bits and therefore deliver audio in its full resolution.

Neutron's audio engine is capable of output to DSD. If you employ Equalizer of other DSP effects and audio hardware supports at least DSD64 then consider using this opportunity to increase the quality of the final sound and to make it more pleasant to your ears.
