Audio Atlas

Audio bugs are invisible until QA or release. Voice limits silently drop sounds. Stereo clips break 3D positioning. AudioSource components consume voice slots at zero volume. Mixer routing fails mid-project with no visible signal. Unity's built-in tools provide no real-time visibility into any of this. Audio Atlas gives you complete, live visibility from a single docked editor window — no scene setup, no code changes required to start. MONITOR: Live Sources tracks every active AudioSource with state clip volume pitch spatial blend listener distance priority and mixer group updated every 3 frames. Mixer Graph renders your full AudioMixer hierarchy as a visual node graph with live signal levels per group populated via MixerAnalyzer. Event Log maintains a 512-entry ring buffer of play stop and voice steal events exportable to CSV. INSIGHT: Health and Metrics displays a composite A–F health grade composed from five weighted sub-scores Voice 25 CPU 25 Design 25 Steal 15 Mixer 10 updated every ~0.5 seconds in Play Mode. The Insights panel surfaces ranked actionable cards clip spam detection fire rate > 10 per second co-occurrence detection paired clips firing within 50 ms and steal burst detection 3 plus steals within 500 ms. ZERO PRODUCTION OVERHEAD: The Editor assembly is fully stripped from all player builds. The Runtime assembly activates only when AUDIOATLAS_DEBUG is defined. Without that define the compiler eliminates all tracking code and the bootstrap becomes a no-op — no runtime cost no binary bloat. KEY FEATURES: Audio Atlas is a 20-panel docked editor window that requires no scene setup and activates automatically on Play Mode entry. The monitoring layer gives you immediate visibility into your audio runtime. Live Sources tracks every active AudioSource in real time exposing state clip volume pitch spatial blend listener distance priority and mixer group. Mixer Graph renders the full AudioMixer hierarchy as a visual node graph with live signal levels per group. Event Log captures every play stop and voice steal event in a 512-entry ring buffer with full CSV export when you need a record of a session. The analysis layer goes deeper. Project Scanner evaluates every AudioSource AudioClip AudioMixer and AudioListener in your open scenes against 12 rules AA-001 through AA-012 categorised across Error Warning and Info severity. Five of those rules include one-click auto-fix with full undo support Ctrl+Z restores the previous state and shows the exact rule ID in Undo history. Signal Chain traces the complete signal path from any selected AudioSource through the mixer hierarchy to the output bus. Source Inspector compares serialized and runtime property values side by side highlighting fields where runtime modification has caused drift from the original configuration. Scene Heatmap renders a 3D audio activity density overlay directly into the Scene View giving spatial context to what the source list alone cannot show. The intelligence layer operates continuously in the background. Health Score computes a composite A–F grade from five weighted sub-scores Voice CPU Design Steal and Mixer and updates every approximately 0.5 seconds in Play Mode. The Insights panel surfaces ranked finding cards for clip spam co-occurrence and steal bursts each produced by a dedicated detection algorithm rather than static thresholds or heuristic guessing. Asset management covers the full project scope. Clip Search inventories every AudioClip in the project with sort filter duplicate detection and unused clip detection exportable to CSV. Memory Profiler reports per-clip runtime memory footprint alongside load type and compression format. Budget Guard enforces per-platform voice and memory budgets and raises live alerts when limits are exceeded. The tools layer supports deeper investigation and production workflows. Session Diff compares any two recorded sessions across six behavioral dimensions. Voice Drop Simulator estimates voice steal probability deterministically across 32 distance samples with no randomisation involved. Waveform Scope renders a real-time DSP waveform with zero per-frame heap allocation. CI Integration exposes a single -executeMethod entry point that runs a full blocking scan writes a structured JSON health report to disk and exits with code 0 for a clean result 1 when issues are found or 2 when the scan fails or times out. Build History records a health entry on every CI run and displays grade trends as a sparkline chart across builds. The underlying architecture is built for zero production impact. The Editor assembly is fully stripped from all player builds. The Runtime assembly is compiled out entirely when AUDIOATLAS_DEBUG is not defined — no tracking code runs no binary size is added and the bootstrap becomes a no-op. EventBus provides 32 typed events with 32 pre-allocated handler slots and raises events with zero heap allocation. AudioRegistry stores all runtime monitoring state in thread-safe pre-allocated ring buffers that are safe to read from editor panels in Edit Mode. Full Disable Domain Reload compatibility is maintained through SubsystemRegistration reset in the bootstrap lifecycle.
