AudioCue - AudioClip Editor & Player

AudioCue is a tool for creating, editing, and playing multi-variant audio assets in Unity projects. It combines a visual waveform editor with a pooled runtime system, ready-to-use components, and a public API.

Group multiple AudioClips in a single AudioCue asset, configure how variants are selected, and control playback from one place. Each variant can have its own range, weight, fade-in, and fade-out.

Key features#

• Multi-variant AudioCue assets
• Random No Repeat, Weighted Random, and Sequential modes
• Visual waveform editor
• Independent trim and fade settings for each variant
• Direct audio preview in the Editor
• WAV export with optional baked-in fade and EQ
• Non-destructive three-band equalizer
• Spatial audio, custom rolloff curves, and AudioMixerGroup routing
• Pooled AudioManager with voice limits and retrigger cooldown
• Controlled overflow and priority-based voice stealing
• AudioHandle with pause, resume, stop, and state tracking support
• Global, positional, and Transform-following playback
• AudioCuePlayer, AudioCueTrigger, and AudioCueMouseTrigger components
• Public API with Play, PlayAt, and PlayAttached methods

Authoring and export#

The built-in editor lets you set the playback range directly on the waveform, configure fades, preview the result, and export the selected section to a new WAV file. The original AudioClips are not modified.

The equalizer works non-destructively during playback and preview. Fade and EQ can optionally be baked into the exported WAV file.

Runtime#

AudioManager uses an AudioSource pool and supports simultaneous voice limits, cooldowns, controlled temporary voices, and priority-based voice stealing.

AudioHandle provides safe control over active playback, including pause, resume, stop, state, and end reason.

Requirements and compatibility#

• Requires Editor 6000.0.81f1 or newer
• The Input System package is required by the runtime assembly
• Runtime and editor tools are independent of the rendering pipeline
• The included demo scene uses the UI package and URP 17.0.4

Updating from Audio Clip Toolkit 1.0#

AudioCue 2.0 is a major, backward-incompatible update. Assets, components, prefabs, and serialized references from version 1.0 are not migrated automatically.

Before importing version 2.0, remove the old Assets/AudioClipToolkit folder, recreate AudioClipData assets as AudioCue assets, and reconnect the required components and events.

Documentation#

The package includes installation instructions, a quick start, an AudioCue authoring guide, API documentation, migration instructions, and troubleshooting.
