Whether it's in the box or not, I think there's fun to be had trying to use different tools.
Last week, I delivered a polished mix to a band.
Today, I've spent the day trying to re-master one of the tracks with just eq's in the RME UCX and my DBX doing multiple bounces to try to get a version I like more than the one I did in the box.
I'm not there yet, but I've done a ton of listening and know more now than I did this morning.
:-)
Some of the differences come from not using multiband compression. With just one compressor, I can't do different bands.
Also, using my hardware, it's harder to get a precise average loudness. it's also interesting to hear a loud part from a vocalist push down the rest of the band. Same can happen for a loud lead guitar. The multi-bands increase the compression just on the notes required while leaving the rest of the recording untouched.
Because you're compressing all bands at once, to get the same average loudness, I have to compress the track harder. When the compression eases off, the other music bounces into the front. It's almost like a vocal rider in reverse. :-) It pushes up whether it in the back of the leads as soon as the leads go quiet.
Super interesting. And also something I'm sure I've heard in a thousands of pro recordings without realizing what was driving it.
Next, I tried mixing the two recordings together, normalizing so the peak was at -0.2 and taking an average volume on the EBU meter. Interestingly, it was a full 2 Db quieter than either recording alone.
