CITY NOISES — Urban Ambience & Street SFX Generator

CITY NOISES is a self-contained urban-ambience generator. It doesn't play back field recordings — every sound is built live from procedural filtered noise, drones and transients, so each bed is a fresh variation you can shape and re-roll.

14 sounds across 3 families:

Traffic & Street — City Traffic (loop) · Busy Intersection (loop) · Highway Rush (loop) · Car Horn (one-shot) · Passing Car (one-shot) Crowd & Commerce — Crowd Murmur (loop) · Marketplace (loop) · Sidewalk Footsteps (loop) · Subway Platform (loop) Machinery & Infrastructure — Construction Site (loop) · Ventilation Hum (loop) · Siren Pass-By (one-shot) · Neon & Electrical Buzz (loop) · City at Night (loop)

Six sliders per family (labels adapt to what you picked):

• Traffic & Street — Level · Tone · Density · Motion · Bright · Space
• Crowd & Commerce — Level · Tone · Density · Bustle · Bright · Space
• Machinery & Infrastructure — Level · Tone · Rate · Grit · Bright · Space

Also: a ↻ New variation button re-seeds the sound; loop cues have a loop-length selector (8 / 12 / 16 / 24 s), one-shots export at their natural length; live waveform + playhead; editable export filename; one click each for Export .ogg and Export .wav.

• In RPG Maker: the loops (traffic, crowd, subway, construction, night beds) make excellent BGS ambience for town, market, station and back-alley maps — layer two or three for depth; the one-shots (Car Horn, Passing Car, Siren Pass-By) drop in as SE on events. Put the .ogg in your project and the baked-in loop tags make BGS loop seamlessly. .wav is there for editing or other engines.
