deemphasis

(1/2) > >>

ZincAlloy:
As ripping CDs with preemphasis ain't easy and LAME can set emphasis flags it would be nice if Rockbox could read the flags and apply the needed deemphasis. 

saratoga:
Could probably be folded into libmad without too much trouble, but I don't have much motivation.  CDs with actual preemphasis are rare. 

ZincAlloy:
Right, it's not very common anymore, but I heard some classic and audiophile labels still use it.

NiHaoMike:
Isn't applying or removing emphasis just a matter of using the EQ to boost or attenuate high frequencies?

saratoga:
Yes, although its probably simpler to use a basic filter in the codec itself rather then try to script changes into the rockbox EQ from inside a codec.
