Reviews audio DSP and audio processing code for realtime safety violations. Use whenever the user asks to review, audit, or check audio processing code — including plugin process callbacks, audio engine render functions, DSP implementations, or any code that runs on the audio thread. Trigger on phrases like "review my processBlock", "check this DSP code", "is this safe for the audio thread?", "review my JUCE plugin", or when you see an audio callback and spot potential realtime violations.…
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 DSP Realtime Safety Review > **The cardinal rule:** *If you don't know how long it will take, don't do it.* > > The audio callback has a hard deadline — typically 1–5ms per buffer. Miss it once and the > user hears a glitch. The three categories of violations that cause this are: **allocations**, > **locking**, and **system calls** — all of which can block for unbounded time. ## Step 1 — Find the realtime context Identify the audio callback and every function it calls (transitively). Common names: `processBlock`, `process`, `render`, `getNextAudioBlock`, `audioDeviceIOCallback`, `AURenderCallback`, `JackProcessCallback`, and the output-stream closure in cpal/JUCE/PortAudio. ## Step 2 — Scan for violations **Memory allocations** (allocator paths may lock, grow arenas, touch new pages, or run unbounded bookkeeping): - `new` / `delete` / `malloc` / `free` / `make_shared` / `make_unique` - `std::string` construction, concatenation, `to_string()` - Container growth: `vector::push_back` without pre-reserve, `map::operator[]` on new keys, `unordered_map::insert`, `deque::push_back` - `std::function` with non-trivial captures (may allocate), throwing exceptions …

How to install
mdr add gourdja/sonic-skills/audio-dsp-review@sha256:18f40621e6a383bdThe line at the top of this page pins the label git:20260521.8b6dcfe, 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.
