Proximal One is a modular, proximity- and trigger-based audio framework for Unreal Engine, built entirely with Blueprints and MetaSounds.
It streamlines the creation of interactive, musically-synced, and spatially-aware audio — perfect for games, immersive experiences, and experimental audio design.
Whether you're composing layered music, designing reactive ambiences, or building dynamic soundscapes tied to gameplay, Proximal One gives you a flexible, scalable foundation with real-time control and fast iteration.
🔑 Key Features:
Proximity-Triggered Audio
Sync audio playback to player movement with musically accurate timing using Unreal’s Quartz clock system.Modular Blueprint-Based System
Drop in a Clock Blueprint and as many Audio Instances as you need—everything is extensible and easy to integrate.Quartz Clock Timing
Select from 5 built in Quartz clocks or use an existing clock in your project for easy integration with existing setups.Built-In Visualizers
See gain zones, proximity curves, and filter ranges live in-editor or at runtime with the abilty to shape the location and direction of proximity variables on each axis.Scale-Aware Pitch Control
Randomized or set pitch values that stay in key, with support for multiple musical scales.Wave Player Remixer
Re-sequence audio with seed-based variations for rhythmic and melodic rearrangement.Custom MetaSounds Support
Integrate your own existing MetaSounds, or use the included patch templates to create your own making use of all of Proximal’s features.Real-Time LFO & Modulation
Modulate gain, pitch, filters and a custom metasound variable using synced or free-running LFOs with randomization, musical pitch scales and AD envelope shaping useful for creating procedural melodies and adding detail and movement to audio.Live Edit Mode
Hear your changes instantly while playing in-editor, and save adjustments on the fly.Flexible Trigger System
Start and stop audio based on player entry/exit of collision box, object collisions, or other instance events—with optional musical quantization.Spatialization & Mixing Tools
Customizable spatialization. Built-in delay, per-instance limiter and compression, reverb sends, and final mix control via submix routing.Lightweight & Optimized
Dynamically selects from optimized MetaSounds based on your settings—only what you need, when you need it.High Quality Demo Sounds
Includes 167 audio samples for different styles of music e.g. ambient, suspense, arpeggiators, Bass, Drums, Melody, One shot synth samples and sound FX.
