If you have the older version of CEP , like 1.2 , you can only tweek the eq in the edit wave page . Under the drop down menu at the top open >
transform > filters > and use either the graphic , parametric or quick filters .
Highlight a section of your wav to make it faster to test the different setting in the preview mode of the filter . Once you find a setting that you like , highlight the whole track/wav under the edit menu . Edit> Select Entire Wav . Make sure you have the " Enable undo " checked in case you mess up . After you select the entire wav / ( you can also just do part of the track if that's what you need ) / go back to the filter you selected and hit OK .
After the file transforms to your new eq setting , go to the file menu and select ' Save Copy as " and rename the file , like if the original was
say " Hard Days Night Vocal lead " save it as that " Hard Days Night Vocal lead with mid boost eq 12 15 05 " .
Later , when you close your session ,CEP will message " Changes have been made to " Hard Days Night Vocal lead " do you wish to save them ?? Say NO , or it will convert the original to the EQed version .
You can still insert the EQed track while your still working on the mix in the Multitrack view . I always save the original tracks till after the whole project is completed , mixed , mastered and burned .
I also burn all the original 32 bit track files , final mixed 32 bit track files , the stereo mix down and the mastered final product as a data disk .
No sense losing all that info after the hours of hard work that goes into it .
