Coping with sub bass frequencies might be one of many trickier features of music manufacturing. A sub bass half might be elusive – powerful to correctly monitor in a house setup, typically not reproduced in any respect by smaller audio system – and they are often very laborious work to combine. However, notably in terms of dance music designed for a robust sound system, nailing your sub might be what makes or breaks your observe.

Put merely, sub bass is something that occurs within the decrease finish of the bass frequency spectrum. The precise definition of sub bass tends to vary relying on who you ask, nevertheless it’s typically thought-about to be something under round 60Hz-80Hz, reaching all the way down to 20Hz, which is the bottom frequency audible to the human ear. For context, the bottom word of a bass guitar is round 41Hz, and the bottom word on a piano is round 27.5Hz.
Sub bass frequencies are sometimes felt greater than they’re heard, however that doesn’t imply you possibly can disregard what’s happening down there. It’s on this vary that almost all synthesised basslines have their elementary frequencies (generally round 40Hz-80Hz). The sub frequencies additionally outline the ability and weight of a observe – too little and a combination can really feel weak and underpowered, an excessive amount of and issues can shortly grow to be overblown and overpowered.
Through the years, sub bass has grow to be more and more vital in dance music, since these are digital genres largely designed to be heard on highly effective membership methods that convey these frequencies to the forefront. Again within the ’90s, jungle and drum & bass producers would use the Akai S-Sequence sampler’s sine waveform ‘take a look at tone’ performed again on a low octave to create sub basslines. In hip-hop manufacturing, a sampled and pitched model of an 808 kick has grow to be a just about ubiquitous technique for creating highly effective, sub-focused basslines.
The concentrate on subs in all probability reached its peak with dubstep – we’re speaking concerning the earlier, UK-centric style right here, versus the US-exported EDM model – which mixed spacious, half-time beats and dub-like results with enormous, chest-rattling bass designed to be skilled on a robust membership sound system. Whereas these purely sub-focused sounds have arguably receded slightly up to now decade, sub frequencies stay an enormous a part of dance music manufacturing. Fashionable techno, for instance, makes use of sub-heavy kicks and low-end ‘rumble’ to create an total darkish and highly effective sound.
One key drawback in terms of working with sub components is how poorly they’re reproduced away from membership sound methods. These early jungle and DnB tracks we talked about earlier than, for instance, appear to lose their basslines fully when performed on smaller speaker methods. There are occasions when this can be utilized to a bonus – consider occasions you’ve heard an incredible dance observe first at residence, then heard it once more in a membership and abruptly picked out entire new components you didn’t hear earlier than…
Nonetheless, more often than not it’s a problem to create highly effective, club-ready sub components that may work properly in a membership surroundings however can nonetheless be heard on smaller speaker methods. Arguably, it’s precisely this conundrum that triggered dubstep’s shift away from its club-centric UK sounds to the full-frequency bass types of artists like Skrillex, which commerce the spaciousness for aggressive mid-range elements that sound ‘heavy’ even on a cellphone or laptop computer speaker.
The opposite facet that makes subs tough from a manufacturing viewpoint is figuring out tips on how to monitor them correctly in a small studio setup, comparable to a house or undertaking studio. Even and not using a sub speaker, first rate monitor audio system will reproduce low frequencies much better than many normal stereo setups, however sub bass can nonetheless get misplaced simply at decrease volumes.
What’s extra, resulting from their low frequencies, sub elements can create what’s generally known as ‘standing waves’. The results of that is that, even if you happen to can totally reproduce these low frequencies, in a not quite perfect studio area sure pitches within the sub area will sound far louder than others, and may not precisely symbolize how a observe will translate to a membership surroundings. We delve into methods to observe your subs at residence later within the function.
Making a sub
Subs are comparatively easy sounds however, as they’re such an vital aspect of a combination, it’s important to get them spot-on. At a fundamental stage, a pure and clear sine wave tends to work finest as a fundamental sub tone – extremely straightforward to create in most synths. Nonetheless, minute changes to a sub patch’s amplitude envelope assault and launch occasions might be essential to cease it from having undesirable clicks in the beginning and finish of every word.
You could must tweak launch occasions additional once you truly get spherical to programming your sub’s MIDI half: it’s not all the time finest to program your sub word’s legato, as area between notes, nevertheless small, is likely to be what your bassline must have the appropriate groove. On this case it’s price experimenting with totally different launch occasions (and if obtainable, envelope curve shapes) to see what settings work finest.
It’s additionally price attempting out the obtainable voicing modes on supply, as a result of in some instances – relying on how your synth’s envelopes work – you may truly discover you get a greater really feel from polyphonic mode. Simply watch out to not overlap notes on this state of affairs, as a result of it’ll sound muddy and eat up headroom like no person’s enterprise!
It’s additionally a good suggestion to experiment with the chances afforded by amplitude stage and pitch modulation. Relying on how busy the remainder of your combine is, you may discover that assigning an LFO to your sub’s pitch can present some welcome additional rhythm and provides your bass half a extra vibey, natural really feel.
To get an excellent mixture of weight and area, drop your sub’s pitch and amplitude stage with an envelope, which ends up in a Roland TR-808-style kick drum sound.
A pitch sweep is an effective technique for increasing a easy sub sound in order that at the very least some aspect of it should reduce via on a weaker sound system. Past this, the best approach to make a sub audible over a smaller speaker system is so as to add some further harmonic content material.
You might strategy this by merely doubling your sound with one pitched an octave or two larger. The higher strategy is usually to create a sound with slightly extra harmonic richness at supply. A fundamental sine wave is the best tone, with little in the best way of overtones. Transferring to shapes like sq. or noticed waves introduces new harmonic overtones above the foundation sub that will likely be audible even when the basic isn’t.
A traditional Reese bass – named after an alias of Detroit icon Kevin Saunderson – is the right instance of this, utilizing two detuned noticed waves to create a bass sound with loads of sub vitality but in addition simply sufficient overtones so as to add loads of combine presence.
Distortion generally is a useful gizmo for emphasising overtones in bass, too. At its easiest, pushing a sine wave sub via a distortion impact can add sq. wave traits. This generally is a nice strategy used on one thing like an 808 bass, to be able to add a little bit of further mid-range grit and presence to an in any other case low finish centered sound.
