Title: Quick Matrixing Advice
Post by: eric51078 on August 30, 2007, 11:55:26 AM

I recorded a show with 2 different recorders and I want to matrix them. Any advice as to how? I am using Adobe Audition which is just like Cool Edit Pro.

Thanks,
eric

Audition has a very good help file - have you checked it?  Also, try a search in the Computer Forum for CEP and/or Audition and/or matrix.

IF using Audition.  Open em up in multitrack.
Make the wave forms as big as possible on the same page.

Find an area with snappy snare drums
zoom in and line up the peaks of the snare (eyeball it).
and mixdown.

Its what I do.
What are your sources?  Aud /sbd or aud/aud

beware of aud/aud and phasing.

You'll still have to deal with the issue of 'drift' since this comes from 2 separate recorders, that is unless you are really lucky and either the 2 recorders' internal clocks were so close they do not fall out of sync with each other by the end of the show, or the show was short enough that the drift is not audible.

Yes.  I forgot to add to track out one source and align the two sources by song.

not the full file.

Does Audition have a time-scaling function so you do have to chop one source by tracks and repeatedly re-align, still potentially having drift at the end of each track?

I took an untracked audience recording and then lined up the tracked sbd song by song using Adobe Audition. It took a while, but the occasional tiny gap was easily covered up by the crowd anyway. Then I just sorted the relative level (raised the sbd until the vocals and music got nice and crispy and the crowd weren't yapping so loudly over the top) then mixed to a stereo wav and proceeded as normal.

Hope that helps.
