Have the following question: I did an interview with two different people. Unfortunately, I've used two different mics. 1. Conference and an indicative micro-micro. At the micro-conference with a hum or background noise can be heard very loudly. At the other micro sound fits very well. How can I runterregeln the background with Premiere Pro 1.5? Is there somewhere a good explanation for the sound effects? There are so many that you nciht know which one to use.
