Title: Pre-emphasis Playback
Post by: dspargo on July 21, 2010, 05:57:46 pm

Why can iTunes (for the most part) play CD's with pre-emphasis correctly and apply de-emphasis but Media Center can't do it.

I LOVE your product and wish this feature could be added.

Any ideas? Thank you  :)

iTunes supports it and MC doesn't.  Was there another question in there?

Can it be added to MC?

I have seen it described as a low priority. Is it difficult to implement?

I think Sox is the best option available today.

I have a few old 80's CDs with pre-emphasis, but it is not commonly used anymore.
Here is what I would do if I still had unripped pre-emphasized CDs:

- Rip to single wav file & cue sheet.
- Process the wav with Sox.
- Mount the "wav + cue" disc image with Daemon Tools, Virtual Clone Drive or some other virtual CD drive emulator.
- Rip the virtual disc to track files with MC.

Alternatively you can use:

- MC's equalizer for a playback correction. Here is a close approximation of the de-emphasis correction:

- and Scthom's EQdB plugin for automating the EQ change:

Thanks Alex  :)

I adjusted the equalizer to the values shown and saved it as a de-emphasis preset.

I wrote a little guide over at head-fi on how to do de-emphasis when ripping a CD: Ripping CDs that have pre-emphasis (http://www.head-fi.org/forum/thread/423506/ripping-cds-that-have-pre-emphasis)
You may find it helpful.  The process is a little bit messy.  You need to run a command line program, manually edit a text file, juggle files around.  That can be a bit daunting if you aren't familiar with using command line programs.  The guide mentions using Foobar to split the CUE into tracks.  You can do the same in Media Center.  Load the CUE in Media Center and it can split it and convert the tracks to FLAC or MP3.
