I have a small vocal problem I'm trying to solve. I'm working on the final version of a song I originally recorded over a year ago. It has become necessary to change a few lines in the lyrics which, in turn, means that a vocal singing the new lyrics needs to be recorded. A year ago I was using a Edirol FA-66 as my audio interface and mic preamp. Now I have a Apogee Duet. The character of the new vocals using the Apogee is quite different from the original vocal track recorded with the Edirol. It seems to have more top end and general definition but its also more brittle sounding. I used the same microphone, and same plug ins and settings and the same mic technique, but the vocals recorded with the duet really jump out in the mix. I no longer have the Edirol unit. Iam I going to be forced to re record the entire vocal or can I fix this somehow?
