呢個小學生問題.....希望各位大學生解答(有關CAS)

MP3格式的音樂檔是否用任可軟件轉換都不能得到高質音樂檔96/24 ,192/24什至係192/32等無損音樂檔?因為MP3格式的音樂檔原本已有嚴重失真?96/24 ,192/24等無損音樂檔是否一定要經CD取樣軟件升頻所得?怎樣先可以得到高質無損音樂檔?

新手一名,希望各位可以教教.

一張bitmap圖片，縮細咗放返大你話會點?

咁我想問下係唔係一定要用軟件從CD取檔升頻先96/24 ,192/24等無損失真音樂檔???

I think the only way to get those HD audio source is buy them via online music store...even upsampling from an ordinary CD is not real high resolution....
For me, I play SACD

Do you mean rip DSD from SACD? I also want to play this! It seems very interesting.

    I just play SACD by a usual SACD player, I don't know how to rip DSD from SACD. I think even the Blu-ray Rom of a PC can't read the SACD DSD layer, am I correct?

I am not sure, but I know old version PS3 + proper firmware can read and rip SACD into DSD file. But I also don't have detail research on this.

Real HD file is not go via upsampling, it is originally recoreded at 24/88.2/176.4/192 or else.

Lossless file not = HD file, 16/44.1 also could be lossless, lossless meams therotically exactly the same as source file, regardless bit and sampling rate.

Some software player can play SACD or Buleray ISO file now, but may not really decodeing at HD format, such as DSD file suppose to be 1bit/2.8M, but the software may convert/downsampling to 24/192 PCM.

    so lossless file recorded at higher bit and sampling rate will be better in sound quality than recorded at lower bit and sampling rate ? {:1_332:}

If the original file is 16/44.1, you use upsampling to record it into 24/192, the quality very depends on the upsampling program, it maybe worse.

So far, for freeware, the best upsampling program should be KORG Audiogate.
