Topic: help with pre-emphasis

[JasonSobel]

hey folks, I'm transferrign some old DATs that were recorded with pre-emphasis (recorded with a Teac DAP-20, which, as I understand it, always had pre-emphasis on when recording via the analog inputs).

I would like to de-emphasize these before seeding, but I'm not sure how to go about doing that.  Can it be done in WaveLab?  I assume so, but I would really like some help here.

thanks in advance,
Jason

found this through Google, from an old DAT-heads post:

Hi,

 I am also working on a tape that has the pre-emphasis bit set.  The Waves
plugin uses a Paragraphic EQ with the settings at -9.4dB @ 5225Hz and 7.0Q for
DAT/CD de-emphasis.  I'm sure if your software has a paragraphic EQ you can
just plugin these settings and get a pretty good approximation of the
de-emphasis EQ curve.

Take Care,
Paul

anyone want to help me with that?  what is "7.0Q" ??  any help here?

it's a setting on a parametric EQ.  If you have Cool Edit or an editor like that you can use a tool called a parametric EQ.  You can punch those setting into it and let it do it's thing.
