KILOWATT — Household Appliance & Machine SFX Generator

KILOWATT builds household machines out of pure DSP — mains-hum harmonics, motor whines, air-noise, sloshing water, buzzers and bells — so a modern-day or slice-of-life game can have a living, humming home without hunting for sample packs. Fridges drone, blenders snarl, vacuums whine, the kettle rises to a whistle, the doorbell dings-and-dongs. Loops are engineered seamless (tonal parts are tuned to complete a whole number of cycles per loop); one-shots are clean-tailed. Sliders push speed, motor body, air and rattle so each machine can be a cheap little unit or a heavy old workhorse.

16 machines across 4 families:

• Kitchen — Refrigerator Hum (loop) · Blender (loop) · Microwave running (loop) · Kettle boil & whistle (one-shot) · Toaster Pop (one-shot)
• Cleaning — Vacuum Cleaner (loop) · Washing Machine (loop) · Tumble Dryer (loop) · Dishwasher (loop)
• Signals — Microwave Beep (one-shot) · Doorbell ding-dong (one-shot) · Alarm Buzzer (loop) · Oven Timer Ding (one-shot)
• Comfort — Ceiling Fan (loop) · Air Conditioner (loop) · Ticking Clock (loop)

Six sliders per family: Level · Speed/Pitch · Motor/Repeats/Hum · Air/Steam/Tone · Rattle/Rumble/Bright/Flutter · Space. Loop length is selectable (8 / 12 / 16 / 24 s) for the loops; one-shots use their natural length. ↻ New variation reseeds.

Perfect for modern apartments and kitchens, offices and labs, a humming break-room, doorbell and timer cues in events, a ticking-clock tension bed, or the background drone of a laundromat or convenience store. Drop the loops into audio/bgs/, fire the beeps and dings as audio/se/.

How to use in RPG Maker (MZ / MV) Loops → export the .ogg into audio/bgs/ and play as a background sound; the baked LOOPSTART / LOOPLENGTH tags make them repeat with no gap. One-shots (beep, doorbell, kettle, toaster, oven ding) → audio/se/, triggered with Play SE. WAVs included for any other engine.
