-
- because the info is recorded digitally in a fixed number of bits,
- there is a fixed maximum number. that means that the CD output
- has a fixed maximum volume, which is that largest storeable
- number run through the D/A and any amplification stages - all
- of which are fixed in the CD player.
-
- if the CD is well engineered, the maximum volume of the music
- to be recorded will be recorded at a level close to the maximum
- integer able to be stored on the CD.
-
- if the processing is all done digitally, I suppose the loudest
- bit can be found, and all the data scaled to fit on CDs, if the
- digital processing uses more bits than the CD, or if the recording
- is done at a relatively low level (although that would imply less
- real dynamic range.)
-
- of course the levels jump around - it is not a fixed level of output,
- it is a fixed *maximum* level of output.
