I started out using a compressor myself.
(like many) And then got into the concept of using two compressors in series. The first one being set for limiting and just jumping on the louder bits followed by a compressor with a much lower ratio for overall conditioning. This is not bad by the way and sort of works OK.
I don't know what got me into editing vocals in a more precise way either except that I am keen on VU rms levels being constant on tracks before a mix for most instruments. So I started checking individual tracks for rms levels and making them more consistent.
Then that followed onto doing something similar for vocals but now getting in and being more precise and detailed about it. Immediately I noticed how much nicer the vocals started to sound. How much less the compressor has to do over the final track.
It's like anything I guess, the more time you put into something the better it starts to sound.
I don't doubt that something like vocal rider will work too. But it is still making decisions based on technical considerations such as what peak and rms levels may be at any point. Like anything it is going to make certain assumptions
(and adjustments) that may in the end not be accurate. Like automatic mastering for example. Whereas when you get in there and edit to great precision and use your ears instead the result will
always be better.
Of course this also applies to lower level singing vocals as well as lower level spoken dialogue which is the topic of this thread. There is also another thread about lower level vocals but it is essentially the same thing as we are talking here.
