CD Pre-emphasis: How to detect? What software to rip? Tagging?

[yamamoto2002]

I have only one pre-emphasis CD, a harpsichord Bach BWV 1080. It is recorded on 1980s.

 

When ripped with Exact Audio Copy, there is pre-emphasis flag is set on its CUE sheet. ripped PCM data is not de-emphasised: raw PCM is extracted to WAV or FLAC. When listened to the PCM without de-emphasis, high frequency is super harsh, with constant high frequency hiss and I cannot bear to listen to it.

 

It must be noticeable the sound is very wrong when you have a pre-emphasis CD and listen to it without de-emphasis.

 

Do you have any pre-emphasis CD ?

If those thin sounding CDs sound normal with conventional CD player, it is definitely pre-emphasis CD.

 

Then it is possible for your USB CD drive to check if it support pre-emphasis detection or not.

with Exact Audio Copy, create cue sheet, open the cue file with a text editor and find "FLAGS PRE"

 

I attached the cue sheet of my pre-emphasis CD.
