Bug Description
Max (0.9.1) reports the track pre-emphasis incorrectly, always reporting "no" where cdparanoia says yes (cdparanoia III release 10.2).
The pre-emphasis flags can be found with
cdparanoia -Q
and reading off the "pre" column. If you don't have any discs with pre-emphasis for testing, one can be created with cdrecord (AKA wodim) using the -preemp flag or by cdrdao using a TOC file with PRE-EMPHASIS track headers. (The macports ports for these are cdrtools and cdrdao, respectively.)
De-emphasis can be applied to ripped tracks with sox, though that does requires the user to install it (sox is in the macports repository):
sox infile outfile deemph
As to why no one has complained before, well most people don't know pre-emphasis exists. If they have a large CD collection, a small number of their ripped albums will just seem overly bright when the ripped files are played back, but they won't know why.
