optimize-audio — Claude Code skill: audio checks and setup

This skill audits Unity audio settings and guides changes for memory use, mixer CPU load, and 3D playback issues. It reports findings before making edits.

What optimize-audio does

The skill checks the build target, output sample rate, mixer assets, and AudioListener count, then gathers AudioSource and mixer details. It routes the investigation toward clip import settings, spatial audio, mixer overhead, or compression quality. Separate paths cover mobile sample-rate changes and streaming.

It runs C# through the Unity CLI in a live Editor, using unity command eval --code '<snippet>'. The command catalog must include eval; otherwise, the workflow stops. The skill presents its assessment and waits for the user before changing anything. Editor statistics are only indicative, so the result must be checked in a device build.

Import settings cannot be changed by editing .meta files directly. They take effect through SaveAndReimport() in the Editor, so an unreachable Editor blocks that workflow.

What it helps with

  • reduce memory used by audio clips
  • investigate DSP spikes and Audio Mixer CPU load
  • fix stereo playback on positioned 3D audio
  • audit audio clip import settings
  • trace artifacts in compressed audio

Example prompts for the agent

  • Check why audio uses so much memory in this Unity build.
  • Find the cause of Audio Mixer CPU spikes and show me the assessment before changing anything.
  • Check stereo clips used with 3D positioning and recommend mono settings.

Questions about optimize-audio

How do I install optimize-audio in Claude Code?

Run npx skills add Unity-Technologies/skills --skill optimize-audio -a claude-code. The skill file is at ~/.claude/skills/optimize-audio/SKILL.md.

What does optimize-audio do?

It inspects Unity's audio setup and guides changes to clip imports or the mixer when investigating memory use, CPU load, or playback problems. It reports its findings and waits for approval before editing.

What does optimize-audio need to run?

It needs a Unity Editor reachable through the Unity CLI, with eval available in the command catalog. Import changes are applied in the Editor with SaveAndReimport(), and results must be checked in a device build.
