With electronic music production, the difference between aweful and amazing is determined by thousands of subtle audio effects.
In most forms of electronic dance music, sub bass synthesizer sounds are used to produce huge, club-worthy bass tones. They are responsible for the stomach-shaking rumble in drum n bass, the smooth vibrations in deep house, and the fat boom in hip hop.
Much like a turntablist uses a crossfader to chop up elements of a record into a mix, music software can be used to chop up audio in your song. When used tastefully, this effect makes songs more rhythmic, danceable, and energetic.
