I recorded an audio track and the level was quite a bit lower than the soft synths and I used the leveling amp to bring it up into the mix.
I usually use compressors but they seem to change the music more, which is usually a good thing.
I use compressors to get it so everything is louder than everything else.
Well you use them to bring up the soft stuff to where you can hear it and tone down the loud stuff so your mix is always as loud as it can be, no dynamics.
That's kind of how music is mixed now, so that you can hear it in the car, soft stuff just doesn't get heard.
