By default, DSD sources will be converted to PCM for playback and handled by the Media Center audio engine like any other file type. The DSD to PCM conversion process converts from 1-bit DSD to 64-bit PCM at 1/8th of the DSD sample rate. The total amount of data from this conversion grows by 8x, so the process is effectively lossless / perfect. Once you have PCM, it will be 64bit @ 352.8 kHz for DSD, and 64bit @ 705.6 kHz for 2×DSD.
HQPlayer最大的优势在于它的滤波和升频,除此之外它的解码算法和传统的CD解码方法相同,只是其随着电脑硬件的增强精度更高更准,特别是PCM从44.1升频512倍是传统CD无法想象的,只使是升频到384k(这个对电脑要求不是很高),要是做好了(也不便宜)和传统的CD(无论什么档次的)比较你会明白两者差距是非常巨大的(这里用非常巨大一点都不过份),当采用poly-sinc-xtr滤波把pcm升频到512倍时,cpu的最低要求是i9-9900k,要是想把44.1k的pcm升频到48x512倍(用poly-sinc-xtr滤波)的话不知32核64线程的cpu行不行,如果你的器材没达到这么高档次时用JRiver Media Center 25软件听感也许会更好。
