Drop-in Unity audio system: music crossfade, pooled 2D/3D SFX, mixer-optional volume control, and persistent settings — production-ready sound in minutes.LensLabs Audio Manager is a lightweight, code-first audio system for Unity that gives your project production-ready sound in minutes, with zero required scripting to get started.Add a single AudioManager component to your first scene and it handles the rest: crossfaded music playback, pooled 2D/3D sound effects that scale to any burst size without hitches, and persistent volume/mute settings — all through a small, documented API you call from your own code.Key features:Singleton AudioManager, persists automatically across scene loads — add it once.Music playback with crossfade and fade-out, using two internal channels so you can transition between tracks smoothly.Pooled SFX (2D and 3D) that grows on demand under load and never drops or cuts off simultaneous sounds.Volume and mute control for Music, SFX, and Master, applied live even to sounds already playing.Works out of the box with plain AudioSources — no AudioMixer required. Assign an AudioMixer later and the same API automatically switches to mixer-driven volume control.Settings (volume, mute) persist automatically via PlayerPrefs, namespaced so they won't collide with your own keys.ScriptableObject-based Sound Library and Sound Definition assets, with custom inspectors (including in-editor clip preview) for organizing audio without touching code.One-click "Build Demo Scene" tool generates a fully working demo scene, sample Sound Library, and volume/mute UI — a fast way to see everything working, and a reference for wiring up your own UI.Full documentation: setup guide, API reference, AudioMixer setup guide, and FAQ.Requirements: Unity 6000.4.10f1 or newer. No third-party dependencies — built entirely on core Unity APIs (AudioSource, AudioMixer, ScriptableObject, uGUI).Known limitation: only one music track is "active" at a time by design, to keep the crossfade model simple. If you need independently-mixed simultaneous music layers (e.g. adaptive/stem-based music), that's out of scope for this version.Language: C#. Source code included — no precompiled DLLs.Built and tested against Unity 6000.4.10f1. The package doesn't use any version-specific APIs, so earlier LTS versions likely work too, but this hasn't been independently verified.Three assembly definitions (Runtime, Editor, Demo) — keeps editor-only code out of player builds and speeds up compilation.Dependencies: none beyond Unity's built-in modules (Audio, UI). No third-party packages required.Render-pipeline agnostic — only touches audio, so it works the same under Built-in, URP, or HDRP.No platform-specific code — relies solely on standard Unity AudioSource/AudioMixer APIs. Developed and tested in the Unity Editor; not independently verified on every platform Unity supports.Included demo content: one generated demo scene, four sample Sound Definition assets, one Sound Library asset, and a handful of original demo audio tracks (see Audio/README.md in the package for their license terms — demonstration use only).Documentation: four Markdown guides included in the package (Setup, API Reference, Mixer Setup, FAQ).The C# scripts, the demo-scene generation tool, and the package documentation were written with the assistance of AI.
