This sound is a 4-second distorted growling bass hit built around a 43.65 Hz fundamental frequency. It layers two heavily detuned sawtooth waves panned wide with a centered square wave and a clean sine sub-oscillator for depth. A resonant 4-pole low-pass filter sweeps its cutoff between 150 Hz and 2000 Hz at 3 Hz, creating a rhythmic vowel-like growl. The signal is shaped by a sharp 5 ms attack and a slow 4-second exponential decay, followed by heavy tanh distortion for aggressive harmonic saturation, and a subtle high-pass filter at 30 Hz cleans up low-end rumble.
This bass hit suits darker electronic genres like drum and bass or dubstep at moderate tempos, especially where a textured, growling sub presence is needed. Its wide stereo saw oscillators can be layered with more focused bass elements, but care should be taken to balance the distortion so it doesn't overpower the mix. Use EQ to carve space for other low-frequency instruments and consider adding compression for consistent presence in dense arrangements.
