vocals are a real BEAR, and so are drums...lol...(shudder) makes one want to make solo instrumentals, lmao.
a mic like a shure sm57 or other similar type of mic, is going to give you a "bassier" sound right from the get go. It emphasiszes bass and de-emphasizes highs. A condenser, cheap or expensive, has a more or less flat freq response...it sounds more "real life" by not bass-ing up the recorded vocals. Plus, they do double duty for other instruments. I like run of the mill
acoustic guitar with a conddenser, and a touch of chorus. Just atouch, lmao.
for learning, i did better at first with cheap condenser mics, just to get my feet wet. The even freq response was easier to play with at first.
this is one aspect of"smooth"
another aspect of "smooth" is evening out the volume swings, they mentioned a compressor...that smooths out the "tops and bottoms" volume wise. Kidna makes it "behave" more. Dont over squish it.
yet another aspect of "smooth" is a tiny bit of verb, or chorus...just a "pinch". Old fashioned quote is: right about the time you start going "whoa...that sounds cool...", reduce it down to about one-third as much effect, lmao. this "smooths" out the sudden stops and starts of vocals...
SOMEtimes, "multing" makes for a "smoothing", and sometimes doesnt work as well...multig is copying the vocal track in, 2,4 or more, tracks identically. You can move them around a millisecond back and forth, applying one effeect to each one, and varying the volumes of them, kinda like tuning several effects in a signal chain up and down in real life.
vocals are a bear...and drums are a pain too.
