The sound waves are often modulated using automation or low-frequency oscillation controlling the cutoff of an audio filter (typically a low- or high-pass filter), or the wave's amplitude, to adjust the waveform (to create a 'wobbly' effect on its parameters). In addition, it is common to utilize a somewhat "twinkly"-sounding gradual rise in pitch during "risers" (pre-drop buildups of white noise), and arpeggio chords, vocal chops or vocoders. Future bass tracks with mainstream pop influences often use supersaw chords, while underground tracks tend to experiment, blending real instruments into the songs and using many different sounds.
Kawaii future bass
Kawaii future bass is a subgenre of future bass, known for its happy and cute timbre and strong Japanese pop culture influences. Often, chiptune sounds, soft square waves, anime samples, percussion instruments, and door and bed squeaks are used. Hyper Potions, Aiobahn, Snail's House, and other producers have produced tracks of this subgenre, with the latter being credited as the pioneer for the genre after releasing an album in 2015. The current evolution of this genre is in the palms of a small community of artists on various platforms, changing the sound to continue to evolve the genre as time advances.
