Cd 定 sacd ?

剛剛學人玩音響， 考慮到sources , 有幾個問題
1. Cd rip 到96/24 or192/24? 定係sacd 先做到？
2. 如果cd rip 只rip 到44.1 的話， hdtracks 果d 96/24 邊到來？ 好似green day UNO 無出sacd , 佢又話有得dl 96/24 , 即係點？

3 Sacd 係2.1 定5.1? 好似 http://sa-cd.net/showtitle/771 ， 見avsforum 話呢係5.1, 簡介都無講{:6_141:}

Thx

Rip normal CD just can be 16/44, if upper level is Upsampling process.
SACD not 24/192 format, it's 1bit/2.8224MHz
HDTracks files maybe direct get from Studio or upsampling(by hardware or software, i m not sure)

Hope can help u...{:6_182:}

Convert speed, less noise, batch programming.

Upsampling is useful when your DAC have a high precision and accuracy in High-Sample Decoding(i.e. Accurate Working in shorter time). But even you cannot recover the details which lost in Hi-Res--> CD.

I see.
I saw some review from avaforum they said hdtracks is quiet useful . Bc you can buy the tracks that I like instead of buying the cd.
Curious to know do they sell real 96/24 music or sth make up by sf?

1. CD 只 rip到 16/44.1, SACD只rip到DSD格式檔同埋要rip的話都幾煩

2. hdtracks 的24/96到192檔有幾個來源，主要是studio的master file，或使用高質素的錄音設備將舊的analog錄音的播放用數碼重錄，留意每個album的介紹有時會有說明的。

3. SACD可以是單層只有SACD格式或hybird做多一層CD layer，CD layer同一般CD格式一樣，只會有2聲道，而SACD層容許最多收錄5.1聲道，當然要收錄幾多聲道在隻碟內是制作公司的選擇，有些SACD表明只得stereo即是只收錄2聲道，有些寫了multi-channel的絕多數會同時收錄stereo及multi-channel，支援multi-channel播放的SACD player便可以選擇取stereo播放定係multi-channel播放。至於multi-channel即是幾多channel? 我接觸過5.0及5.1的SACD碟，聽聞也有出過4.0的碟但我沒見過，但碟身及盒面都只會標示multi-channel而已，不過大部份multi-channel碟都是5.1。
