01. Loika
Loika turns your browser into a complete, professional audio processor—featuring an 8×8 routing matrix, parametric EQ, dynamics, crossovers, and FIR—powered by real DSP running in real time, not a simulation.
Every biquad filter, every soft-knee compression curve, and every metering display you see plotted is exactly what your ears are hearing: theory and sound, side by side.
For teaching audio and sound engineering, it is unrivaled: students can adjust a Q, a frequency, or a threshold and instantly watch the transfer function, phase, and gain reduction change, connecting RBJ mathematics with the audible result. It also features loudspeaker management capabilities typically found only in consoles costing tens of thousands of dollars. And all of this without installing a thing, without expensive hardware, and with built-in safety protections—the entire classroom can experiment, break things, and learn completely risk-free.

06. Agata Ripple Tank
A 2D acoustic simulator that solves real sound wave physics in real time on the GPU using FDTD (Finite-Difference Time-Domain). A digital ripple tank designed to model bass enclosures, horns, and subwoofer arrays—visualize how waves behave and interact before building anything.
Draw rigid walls, absorbers (with absorption coefficient α), enclosures, polygons, and folded horn paths. Place 1 to 1,000 sources using array helpers: line arrays, arc arrays with delay steering, and end-fire cardioid configurations. Load driver Thiele-Small parameters, view live pressure and SPL maps, and measure with probes that record time-series data and FFTs in the measurement dock.
