not sure if i post here... i need all info on this type of disc like Data rate, Bit rate, sampling rate, sample size and how big are the audio files and anything else need to know because my friend try to rip it but it doesnt sound that same shes ripping it on a cd/dvd drive any info and help plz
See http://www.cdjapan.co.jp/music/essentials/shm-cd.html It seems like it's a standard CD made by a different process - which is interesting, but as it's apparently Japan only I have never seen or heard one so cannot comment. I get the impression it is still 16-bit 44.1KHz. Smells of marketing BS to me, I have to admit. No matter what plastic or metal the disc is made of, the audio is still the same.
