Question [SACD] Super audio cd...

Mi hanno regalato un super audio cd. Ora, essendo sprovvisto di lettore super audio cd (e chi ce l'ha??) vorrei sapere, prima di aprire suddetto cd (per evitare problemi nella sostituzione del prodotto) se il mio pc lo legge. Ovveroissia:
- il superaudio cd è un cd normale o è proprio un formato diverso, incompatibile con i lettori cd (il mio lettore è anche dvd)?
- se lo posso leggere con il pc, esistono software facilmente reperibili che supportino tale formato?
- qualcuno mi dice qualcosa su questo formato, che sinceramente non conosco (anche perché non ha preso molto, direi...)?
Grazie

So che ci sono i lettori dvd da tavolo che leggono anche i Super Audio Cd, praticamente te lo senti in Dolby 5.1. Se lo metti nello stereo normale nn dovresti sentire la differenza da un cd normale xche` ci vuole un`impianto in pregio. Mettilo nello stereo e dovrebbe andare!

Ok. L'ho aperto e funziona... dentro c'erano tutte le spiegazioni del caso. Primo: non tutti i super audio cd funzionano sul lettore cd normale, ma solo gli ibridi, cioè quelli che hanno due strati (uno strato cd e uno sacd). Lo strato sacd è a sua volta diviso in tre parti: una contiene i dati audio stereo (il vantaggio rispetto al cd è semplicemente la maggiore capacità di rappresentare le dinamiche: i suoni oltre i 96dB su cd si sentono come 96dB, mentre il sacd, come il dvd, arriva fino a 110/120db), una contiene i dati audio in 5.1 e l'ultima parte ha contenuti extra (testo et similia...). Naturalmente ci vuole un lettore sacd... vabbeh...

:shock:

e la differenza si sente per davvero o stà solo nei grafici??

ho visto che le autoradio della sony lo supportano. ma se ci ascolti un cd normalissimo ed hai il lettore sacd la differenza non è molta, vero?

Se ascolti un cd su qualsiasi lettore è sempre qualità cd! La differenza sta nel numero di bit usati per campione, che nel caso dei dvd e dei sacd è maggiore dei 16bit del cd. Inoltre se hai un sistema di casse 5.1sorround la differenza si dovrebbe proprio sente e credo sia piacevole... ma in fondo la stessa cosa la fanno i dvd e i lettori dvd sono molto più diffusi, quindi credo che i sacd non avranno molto futuro...

ma in teoria i 16bit/44Mhz non erano il massimo utibile :D
e che i campionamenti superiori servono solo per l'editing?

Per la frequenza non ti so dire... in effetti non credo che si possa sentire molta differenza. I 16 bit sono un limite per le differenze di dinamiche...
