Say you’re working on a track that needs a touch of humor, maybe a children’s project or a lo-fi beat with barnyard vibes. Suddenly, you realize—you need a realistic pig sound. No, not a sample from a dated library. You want to craft it yourself, twisting knobs and shaping waveforms until your synth oinks. As a producer who once spent three hours trying to replicate a goat’s bleat for a psychedelic folk track (true story), I’m here to guide you through the delightfully weird process of creating pig sounds using XFer Serum.
Pig vocalizations are a messy mix of grunts, squeals, and snorts—a chaotic blend of low-end rumbles and high-pitched harmonics. Serum’s wavetable engine is perfect for this because it allows for precise manipulation of harmonics and noise, essential for mimicking organic sounds. Historically, synthesizers have been used to create animal sounds in films (think Star Wars bantha cries), but Serum’s modern flexibility lets you go beyond presets and get weird.
Step 1: Start with the Right Waveform
Pig grunts sit in the lower mids (200–500 Hz), while squeals shoot up to 2–4 kHz. To replicate this:
-
Oscillator A: Start with a sawtooth wave. Saw waves are rich in harmonics, mimicking the nasal texture of a pig’s squeal.
-
FM (Frequency Modulation): Apply light FM from Oscillator B (sine wave) to add grit. Adjust the FM amount until it feels “snorty.”
Pro Tip: In 2021, I accidentally created a perfect pig snort while experimenting with FM on a bass patch. The key was setting Oscillator B’s pitch 7 semitones higher and using a 25% FM blend.
Step 2: Modulate the Filter for Dynamic Grunts
Pig sounds aren’t static—they warble and shift. Use Serum’s LFO to modulate the filter cutoff:
-
Set up an LFO with a random wave shape (Serum’s “Mega Random” works great).
-
Assign the LFO to the filter cutoff of a low-pass filter.
-
Adjust the LFO rate to ~2 Hz for a natural, erratic grunt rhythm.
Real-World Example: For a commercial jingle, I automated the filter’s resonance to spike briefly during “squeal” moments, mimicking a pig’s sudden high-pitched outburst.
Step 3: Layer Noise for Authentic Breathiness
Pig sounds are breathy and noisy. Serum’s noise oscillator is your friend here:
-
Enable the Noise Oscillator and select the “Pink Noise” preset.
-
Use a high-pass filter to remove rumble, then blend it subtly with your main oscillator.
-
Assign an envelope to the noise level so it spikes during attack phases (like the start of a grunt).
Historical Nugget: Pink noise was famously used in the 1980s to create the “breath” sounds of the Xenomorph in Alien. Pigs aren’t aliens, but the principle’s the same!
Step 4: Add Movement with Effects
-
Reverb: A short, dense reverb (try “Room” settings) places the pig in a barnyard.
-
Distortion: A touch of Serum’s “Downsample” effect adds a raw, gritty edge to squeals.
-
Pitch Modulation: Assign a slow LFO to Oscillator A’s pitch (±5 cents) for unstable, “living” vibrato.
Personal Anecdote: Once, while demoing this patch live, an audience member yelled, “Is there a pig backstage?!” Mission accomplished.

Why Bother Making Pig Sounds?
Beyond the novelty, synthesizing organic sounds sharpens your sound design skills. You learn to listen critically—how a pig’s grunt has a sharp attack and slow decay, or how its squeal resembles a distorted violin. Plus, it’s a riot to surprise collaborators with your farmyard synth wizardry.
So fire up Serum, embrace the absurd, and remember: If Mozart had a synth, he’d probably have made a pig symphony too. 🐷🎛️
