Durin Gleaves at the Adobe Creative Cloud blog has an awesome article on the new Essential Sound Panel in Adobe Audition for mixing DIalogue, Music, Sound Effects, Ambient or Environmental Audio in easy, but powerful ways. It can even retime or recompose a music clip to match a certain time!
Well worth a read, I am looking forward to trying this out, though wish it was integrated into Premiere so I don’t have to do a separate mix, but could instead have it happen with the timeline (which I already put on different tracks for different mix types).
