Dubstep Sounds come in a million different timbres, tones, keys, speeds and textures. The most frequent by far thematic element among all of them are fixation with beat (drums are the whole basis of electronic dance music), and speed.
You need a dubstep sample pack that contains a truck-load of regular mixed beats, drum sets, drum breaks, and single drum hit samples. But you also must have odd, off-beat and hard-to-come-by dubstep sounds that make for a large sonic palette for a musician to draw from.
Do You Like Your Low Register Wobbled or Dropped?
Besides the emphasis on bizarre rhythm and beat patterns, low-register is the other sign of dubstep sounds. And if the bass isn't wobbled, then it likely ain’t dubstep!
But what is wobbled bass? Its the technique of rhythmically changing a deep (usually buzzing) bass line after the downbeat of the measure. Obscure, very geeky sound manipulation techniques like filtering, fast fourier transform or distortion are normally used to achieve the wobble type sound.
The “drop” is the most fundamental formal constant in dubstep, and not specifically a “dubstep sound” per se. But if we’re talking about sounds in their most basic form, then the lack of bass in the first minute or so of nearly every dubstep track - and then the conspicuous, in-your-face introduction of it near the 1 minute mark (most dubstep tracks are 140beats-a-minute, and 32 measures of intro end close to 55 seconds) - then you’d definitely need to mark the “drop” as an critical dubstep sound.
The remaining important element of the most trendy dubstep The very last crucial piece of the most trendy dubstep type in America - aka "brostep" - is the grating and sometimes nasty timbres that typically come with the drop. This is the style that made Skrillex famous.. Forget subtle use of sub-bass frequencies and well-balanced EQ range - Skrillex-style brostep is a aggressive, screeching, in-your-face sound. You need a massive assortment of off-kilter samples and loops to realize a similar result in your dubstep tracks.
One last parting remark: worrying about audio as well as cobbling together clips, samples as well as loops is definitely pleasurable, but it could be unproductive from precisely what the main goal should always be: creating great songs! So remember to focus on the composition, the melody, harmony and rhythm - and focus on making a great hook. The "production" will come naturally!
