J'ai trouvé une explication là :Papalou a écrit :En l'occurrence, le DXD, c'est du PCM à 352 ou 384 KHz (je ne sais plus si c'est 8 x 44,1 ou 8 x 48 )... Tu veux dire DSD j'imagine ?
"DXD is defined as a 24-bit signal sampled at 352.8kHz. The advantage of DXD is that the signal is not limited to a one bit representation like the DSD format. A-D convertors can therefore be used having a higher order delta sigma modulator of 5 bit, for example. Using higher order modulators in fact makes it possible to have a significantly lower level of high frequency noise, thus improving the conversion quality. Since the sample rate of DXD is 8 times 44.1kHz, the signal is easily up-sampled to DSD without any degradation. The data rate for a DXD mono signal is 24bit times 352.8kHz, which is 8467,2MHz, being three times the data rate of the DSD64 signal.".
