Weapon Charge-Up

How it's made

Source

a capacitor-style energy weapon spooling up. A stack of detuned saw and sine oscillators forms the whine; a band-passed noise bed is the plasma hiss; a sine sub gives the felt power-up swell.

Body

the whine sweeps exponentially from ~180 Hz to a peak pitch of 1.4-4.5 kHz behind a low-pass whose cutoff opens in step, so the spectrum brightens as the pitch rises; an octave-up partial fades in near the top.

Envelope

level and pitch accelerate together over the charge time, holding full level for ~30 ms, then a 0.18 s release; a short high-passed shimmer burst at the peak is the bright "ready" crack.

Events

charge pulses are 45 ms sine/noise thumps whose gaps shrink (t = T * (k/N)^0.55), so the beat accelerates into a near-continuous flutter; each pulse is tuned to the sweep pitch at its time and grows louder.

Variation

`rng` detunes the oscillator stack by up to 1.5 %, jitters pulse timing and strength; presets differ in charge time, peak pitch, pulse count and grit.
