Profiling strategy for audio CPU issues — xruns, spikes, and buffer underruns. Use when the user reports CPU overload, audio glitches under load, or performance regressions. Trigger on phrases like "I'm getting xruns", "my plugin causes CPU spikes", "dropouts under high voice count", "audio thread is too slow", "how do I profile my DSP". References audio-numerics-review for denormal slowdown and audio-dsp-review for lock contention.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Audio Performance Debug Audio performance requires good worst-case complexity, not average-case — the audio thread fires on a hard deadline every buffer, regardless of what else is happening. ## Step 1 — Identify the symptom Measure before guessing. Different symptoms point to different root causes. | Symptom | Measurement approach | |---------|---------------------| | Consistent high CPU average | CPU meter in DAW; `perf stat` / Instruments Time Profiler | | Sporadic xruns / dropouts | Host xrun log; correlate with system events (GC, network, page fault) | | CPU spikes on note-on | Profile with many simultaneous note-on events; watch for allocation spikes | | Latency reporting wrong | Log `getLatencySamples()` before and after `prepareToPlay` at varying buffer sizes | | Gets worse with more voices | Profile with 1 vs 8 vs 32 voices; O(N²) shows quadratic growth | | Memory bandwidth pressure | `perf mem` / VTune memory bandwidth counter; cache miss rate | ## Step 2 — Locate the hotspot - [ ] Build a release (optimized) binary before profiling — debug builds are not representative. - [ ] Use a reproducible test case: fixed buffer size, fixed voice count, looped audio. …

How to install
mdr add gourdja/sonic-skills/audio-performance-debug@sha256:259cd476f47fbe1eThe line at the top of this page pins the label git:20260515.3a80b75, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
