Sub Bass : Let's Clear It Up

What are some techniques used in sub basses. im trying to get to the bottom of it.

What i usually do is find a sub base on a preset on the VST that im working on. EW the sub bass for to an extra punch then add WAVE's Amp Stero.

music genre: uplifting trance

am i missing something else?


Some tips to help each other out would be helpful.

low cut / high cut add a bit of harmonics or distortion to get punch and drive, sidechain to let the kick through calculate your ms/bpm for release

You can easily create a subbass by taking a simple sine waveform and play it at a lower octave. Cut all the high and there you have your sub, you can add a pulse or square wave to add some harmonics. It's really not that much work!

It's just a sine wave, man.

Thanks for the info. Would I need to take some off the low end as well. Say 30-40 hz?

Take a look at this pic. Which is the best way to roll off. Top or bottom pic? Thanks.

I'd say the top one, and maybe cut off a little more that that. You can cut off the low end (max 30-40Hz), it will give a cleaner sub. Don't take out to much though!

one should still shelve off below 40 or 20 hz tho yes? Also, I find as soon as my subbass is even the least bit audible my ears start hurting... so mine is usually rather silent and about -18db relative to all else

Most clubsystems won't go below 50Hz, so between 20 or 40Hz is good. To get your subbass audible, you could add a saw or pulse (as I said above ), to add some extra harmonics and make it a bit more audible.

cheers for the reply

I've never thought to hi-cut my sub-bass (not sure why!), but I guess whenever one can free up parts of the sound spectrum without losing sound quality one should do so. At what frequency do you typically cut your sub-bass? Are we talking everything above 300hz? Lower? Higher? Etc.

Also, re: adding a pulse/saw/square wave to bring out some harmonics, do you usually keep the volumes of the two waves (i.e., the sine + the pulse/saw/square) about the same, or do you favour the sine over the harmonic-adding wave?

Take a sine wave , (or try a sawtooth or combine both together)
play it at a low octave , LP filter with a very low cutoff frequency , EQ , and there you have it.

For uplifting trance , most sub bass are pretty simple. Try BooBass.(Its for FL only thou)

Higher frequencies on the subbass are useless, so you can cut them. Where you cut them depends on where you want your bass to be, I usually have it very low, so I cut from 120 - 150Hz down (sometimes even lower).

If I'm adding another waveform, I keep the level of the sinewave highest, afterall, it's the sine that produces the subbass, the other waveform is just extra. You have to find a nice balance between the both of them.
