Super Audio CD (SACD) is a technology for high resolution multi-channel digital audio recordings proposed by Sony and Philips. SACD albums must contain one layer with the "Direct Stream Digital" encoding format which requires a SACD capable player. "Direct Stream Digital" encoding will be able to provide a frequency response from DC to 100 kHz with a dynamic range of 120 dB. Multichannel SACD players have 6 outputs and can play 5.1 or 6 channel audio. SACD albums can optionally contain a second layer encoded with the CD-format (PCM at 44.1-kHz/16-bit) in stereo allowing compatibility with existing CD players.  1, record 4, English, - Direct%20Stream%20Digital%20encoding

La technologie DSD est basée sur une méthode de numérisation appelée Pulse Width Modulation(PWM), un codage prônant la simplicité du phrasé numérique compensé par une très haute fréquence d’échantillonnage. En travaillant à la fréquence de 2. 822 MHz(64 fois plus élevée que celle du CD-audio), le modulateur Delta Sigma chargé de traduire la courbe de tension analogique en un signal numérique binaire prélève en continu quelques 2. 822. 400 échantillons par seconde sur la source linéaire.  1, record 4, French, - encodage%20DSD

DPCM. The simplest form of predictive compression operates at the pixel level with a technique called differential PCM (DPCM). In DPCM, we compare adjacent pixels and then transmit only the difference between them. Because adjacent pixels often are similar, the difference values have a high probability of being small and they can safely be transmitted with fewer bits than it would take to send a whole new pixel.  3, record 9, English, - differential%20pulse%2Dcoded%20modulation%20coding

Le codage DPCM(Delta PCM ou modulation Delta) permet de réduire l'encombrement en codant la différence entre les valeurs successives échantillonnées et non plus les valeurs elles-mêmes. Le nombre de bits nécessaire pour le codage est moindre.  1, record 9, French, - codage%20DPCM

(La voix mise en bits.) Plusieurs méthodes de codage se côtoient. La plus courante est la modulation par impulsions codées(MIC) qui correspond à un débit de 64 000 bits par seconde, encore trop élevé.
