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 3, 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 3, French, - encodage%20DSD

La modulation de phase est semblable à la modulation de fréquence. Certains émetteurs pilotés au quartz sont d’abord modulés en phase à la sortie de l’oscillateur pilote et, avec multiplication de fréquence, on obtient de la modulation de fréquence à l’antenne.  5, record 4, French, - modulation%20de%20phase
