HydroSwarm — Motion-Driven Creative FX Engineby SWARM.AUDIO.DSP
Website (https://swarmaudiodsp.web.app/) | Gumroad (https://swarmaudio.gumroad.com/l/hydroswarm)
HydroSwarm combines four DSP modules in a single signal chain, designed for producers who want sound that evolves on its own — not sound that sits static until you automate it.
The Four Modules:
FILTER — Dual Morphing SVF
Two independent State Variable Filters, one per stereo channel. Each morphs through 5 modes (LP, HP, BP, Notch, Allpass) with ADAA anti-aliased saturation. Independent rate and waveform per channel for evolving stereo motion.
DELAY — Varispeed Flanger-Delay
Independent L/R delay times (10ms–2s) with tempo sync (7 divisions), ping-pong routing, tape flutter modulation (FLUX), tone shaping, and soft-clipping drive in the feedback path.
REVERB — Algorithmic Shimmer
8-line FDN with Hadamard mixing matrix, CloudSeed-inspired pre-diffusion, and +12 semitone pitch-shifted shimmer feedback. M/S width up to 200%. Harmonics cascade and multiply — space that evolves beyond the room.
EQ — 8-Band Modulated Parametric
Studio-grade 8-band parametric EQ with live spectrum analyzer. Each band has its own independent LFO (5 waveforms), modulating frequency and gain separately. Creates spectral motion impossible with static equalization.
Signal Chain:
INPUT → FILTER (Dual SVF) → DELAY (Varispeed) → REVERB (FDN-8) → EQ (8-Band) → OUTPUT
Visual Design:
Every control uses animated 3D wireframe geometries — 23 unique shapes that rotate and deform in real time, providing visual feedback of every parameter state.
Technical:
- C++17, JUCE 8.0.6, Signalsmith DSP
- Kaiser-sinc8 interpolation
- ADAA saturation (anti-derivative anti-aliased)
- Lock-free audio/UI architecture
- Zero latency
- Any sample rate
