Design one RBJ-cookbook biquad and report its numerical behaviour. The identical function behind the /lab/biquad coefficient tables. Returns coefficients at the requested sample rate, coefficients at every other rate whose Nyquist limit clears the corner, pole/zero geometry, the −3 dB points solved by bisection, a Q sweep, a gain sweep where the type uses gain, and the quantised forms. The 240-po

Solve the eigenmodes of a rectangular room. The identical function behind the /lab/room-modes instrument. Dimensions are in feet and are converted at 0.3048 m/ft. Returns every mode below maxFreq, the three axial fundamentals, mode pile-ups (three or more modes within 5 Hz, capped at 200 Hz because dense modes above the Schroeder crossover are desirable rather than a defect), the widest axial gap

Decide whether one LLM fits one accelerator, at every quantization. The identical function behind the /lab/llm-vram instrument. Returns one row per quantization (FP16 through Q3_K_M) with weight bytes and their basis, headroom, the largest context that fits, and the bandwidth-limited decode ceiling; plus the chosen best-fitting quant, the full-precision row, and a five-state verdict. Model geomet

Solve the on-axis magnetic field of an air-core solenoid. The identical function behind the /lab/solenoid table. Returns the centre field per amp-turn and at the requested turns and current, the on-axis profile out to three half-lengths, the span over which the field holds to within 1% and 5% of its centre value, the field at the coil mouth as a fraction of the centre, how far the infinite-soleno

Solve the best rectangular room proportions for a given volume. The identical function that renders /lab/room-shape/{lo}-{hi}. Give a room volume in cubic feet and get the proportions to build: the length and width as multiples of the ceiling height, the exact dimensions at your volume, the widest axial gap they leave, and how far those proportions sit from a full solve at your exact volume. Also

Solve an ideal Gaussian laser beam: Rayleigh range, divergence, radius at a distance, and the waist behind a focusing lens. The identical function behind the worked examples on /lab/gaussian-beam-calculator, built from the same q-propagation the calculator runs. Give a wavelength and a 1/e^2 waist radius to get the Rayleigh range, the far-field half-angle divergence and the depth of focus. Add `d

Solve a two-mirror laser cavity: g-parameters, stability, and the TEM00 waist and mirror spot sizes. The identical function behind the worked examples on /lab/optics-bench, built from the resonator code the bench runs. Give the mirror spacing `l` (cm), each mirror radius `r1`, `r2` (cm; positive is concave toward the cavity, negative convex, omitted means flat) and the wavelength `w` (nm). Return

Solve a vented loudspeaker box for the length of round port to cut, with both end corrections, the smallest workable diameter and the peak port air speed. The identical function behind the worked examples on /lab/port-length-calculator and the calculator itself. Give the net box volume `vol` (litres), the port inside diameter `dia` (cm) and the tuning `fb` (Hz); `temp` (deg C, default 20) sets th
