From the internet. At present the Industry Standard sound quality is based on the specifications of the Red Book Convention, which is a sampling rate of 44.1 Khz and a word resolution of 16 bits. A music production is considered to meet the Industry Standard when its frequencies show adequate harmonic balancing with alignment of the 3 main densities: Bass (20-300hz) Middle Range (1K-8k) Hi Frequencies (10K-20K) The music should sound punchy and clear, with good dynamics and max. high peaks at -0.5 db, (depending on music style). Output levels should never be too loud as it means that the dynamic range has been compromised ("crunched"). A refined mastering job would show adequate individual alignment within a 25 to 30 frequency spectrum (our mastering standard).
