16-bit CD audio suffices for most program material while 24-bit exceeds delivery needs
Evidence
On the right are shown the dynamic ranges of some digital record/playback systems, showing that the conventional 16-bit CD, if well used, has the potential to be a satisfactory delivery format for most program material. But 20 bits would be better, allowing leeway for some imperfection in the process. And 24-bit systems permit the encoding of everything from “I can’t hear it” through to “I’ll never hear again”. It makes sense in recording studios during the creative process, but it is excessive as a delivery format. Taking full advantage of wide system dynamics requires some serious power from amplifiers and loudspeakers, as is shown in Figure 9.3. — Toole, Floyd E, Sound reproduction- the acoustics and…, 934
