here's what I found on one of my tracks:
BASS AND PERCUSSION
kick: peaks at 80hz and 2.5khz without muddying up the whole section between the peaks.
prognosis: OK
bass: peaks around both 40hz and 120hz (depending on the note being played) with plenty of stuff going on all over the place.
prognosis: probably should cut some mud after the 1rst harmonic of the 120hz (ie... above 240, so around 360 or so)
snare: peaks at both 160hz (body of snare) and 1khz (rim) with energy all over the place.
prognosis: I want to cut some of the beef out of the snare but I don't want to make it whimpy... so I won't cut nothing.
congos: 140hz to 1.25khz with great separation of each congo part.
prognosis: nothing to change.
hats: tip at 8khz and stomp at both 50hz and 200hz.
prognosis: got to get rid of the 50hz stuff.
INSTRUMENTATION
clav: 65hz to 3khz with good clarity.
prognosis: might want to high pass at 80hz but I'm not going to screw too much with something that sounds good.
rez pad and strings: 550hz to 5.5khz
prognosis: I'll keep both and pan them apart.
rhythm guitar: 600hz to 10khz with the peak around 2.5khz.
prognosis: sweet... no worries
lead guitar: peaks at 315hz with nice upper harmonics.
prognosis: great clarity and R&B punch... no worries
Overall prognosis: track has good part separation. needs to tame the upper mid bass frequencies. a little more separation via EQ will sit the clav between the bass and strings nicely.
SpectR may just be the the thing I needed to help me 'hear' what
my alesis monitor one's don't let me hear.
