Layering Sub-bass

Just one low sine.

You don't want phase or any other weird shit going on down there.

do whatever. try something new. if it work it works. its how u learn

layer it with freqs higher up the register - no need to have 2 80Hz waves going off at the same time, like dubstez said, it'll get phasey

don't really have to eq the sub bass as much as u have to eq the other shit to clear space for bass.

low pass filter your sub. then layer mids on top, high pass those. make sure your frequencies aren't fighting with eachother. leave room for your kick and snare. like they said above, play around with what sounds best.

sometimes i only have one bass sound sub and all- my synth patch will hit low enough to where i just compress and it's fine. it all depends on what sound you are going for.

it never hurts to resample, bounce it out and then add filters, distortion, compression... notch filters are always fun for the mid bass sounds.

wrong!!!!

I put a lowpass filter with a little knee around 50hz and

BOOM!!!

HUGE SUB

that hits on every note BTW

plus you are making space for the midrange basses

for pure sine sub bass - on whatever synth youre making the sub on, a good idea is to introduce a 2nd oscillator about 30% into the mix, set as a sine wave one octave (or 12 semitones) above your main sub bass - this gives you a bit of bass when people are listening to it on hi fi speakers etc which arent gonne be able to smack out 40hz sine waves too well at all.

if youre just using a sine as your sub then no eqing is needed really, maybe a slight curve upwards from about 30hz to 20hz as the bass will start to lose volume the lower it goes, and this should compensate. you want to keep your sub the same volume at all sub bass notes when on a big system.

Dont boost between 20-30hz. Are ya mad??? i cut all my bass at around 30hz so that the bass is more efficient and wont sound wack on PA speakers. Personally, i think You will be able to create a better mix this way.

if you're playing on a rig, the fucking huge 12k of wattage going into the subwoofers or whatever are not the same as PA speakers are they. have you ever played your tunes out on a big rig? i have, and the infrabass bins on the rig can hit down to around 20hz, and it sounds huuge. why cut at 30, this is dubstep.

^^^

A decent rig set up is going to have it's own DSP with limiters set at optimum levels for the rig in question to save any red lining retard dj's (sorry!) from blowing up the fucking system which no doubt costs more than you would comfortably want to pay out to repair/replace damaged amps & cones.

Keep your sub going down to 20hz or so to allow for such systems that could play it, but any lower and it becomes a waste of time. It's going to be limited by the rig's processing, the physical properties of the cabinets, what the amp can usefully drive that far down, and how the vinyl's cut.

BASS: how low can you go?

This is actually true. A true sine wave has no harmonics, i.e. it's just the fundamental frequency (e.g. 50Hz)

However it's damn near impossible to create a perfect sine wave so synthesisers emulate the sound of a sine wave with a combination of other waveforms.

keep in mind that hi-passing something doesn't mean you completely cut out the material below it-- not even at 48db/octave. you just attenuate it. especially if you're talking about something as low as 20hz.

FWIW 20hz will come through on a big 12k watt rig-- it's just not the huge amount of difference you might expect it to be. a fundamental sine wave at 22hz is almost the equivalent of the A 4 octaves below middle C-- that's really, really, really low. If it's super loud on a wicked rig that doesn't have some junk dbx limiters strapped across it (ie-- love in NYC, valve, and other rigs of that calibre) you'll feel it. if not... extremely doubtful.

give a bump on a sine @ 50hz and you're creating distortion around the Q points of that bump, thereby creating harmonics. if it sounds good, do it. most digital sine waves start to sound cold because there's no analog output from a synth to even slightly distort the wave and give it some heft.

w/ that said-- it's less about the tools used and more about how it affects people. a cold, bottomless sub can do wonders in the right tune. experiment-- it's all about the end product.

use a spectral analyzer
