audio-signal-flow-explainer

Traces and documents signal paths, bus/aux architecture, and sidechain connections in audio systems. Surfaces hidden coupling between audio components. Use when the user asks to trace a signal chain, explain audio routing, understand an audio graph, locate sidechain sources, or describe how audio flows through a plugin or engine. Trigger on phrases like "trace this signal chain", "explain this audio routing", "what calls what in this audio graph", "where does the sidechain come from", "how does audio flow through this plugin".

Audio Signal Flow Explainer

Core principle: Audio signal flow is a directed graph. Tracing it reveals hidden coupling, latency paths, and places where the signal can be corrupted.

Step 1 — Map the graph

  • Find all sources (oscillators, audio inputs, file readers, generators)
  • Find all processors (filters, effects, gain stages, dynamics)
  • Find all routers (bus sends, parallel splits, sidechain taps, mixer channels)
  • Find all sinks (audio outputs, recorders, meters, analyzers)
  • Note parallel paths — any branch that rejoins a main path
  • Note feedback loops — any path where output feeds back into an earlier node
  • Note sidechain connections — signals that control a processor without passing audio through it

Step 2 — Identify each node type

Node typeWhat to note
Source (oscillator, audio input, file reader)Sample rate, channel count, sync source
Processor (filter, effect, gain)In/out channel count, latency added, stateful or stateless
Router (bus send, parallel split, sidechain tap)Where signal copies go, gain staging at split
Sink (audio output, recorder, meter)Expected format, callback timing, buffer size

Step 3 — Surface issues

  • Latency compensation mismatches on parallel paths
  • Channel count mismatches between connected nodes
  • Sidechain input not wired — processor receives silence as control signal
  • Uninitialized state in feedback loops (DC buildup, NaN propagation)
  • DC leaking into output (missing highpass or DC-blocking filter)
  • Sample rate mismatch between source and downstream processor
  • Gain staging that causes clipping before a later limiter or saturation stage
  • Missing denormal protection in recursive filter paths

Step 4 — Write the signal flow description

Use this format:

## Signal Flow: [component/system]

### Graph
Source → [gain: 1.0] → [Biquad LPF] → [Comp sidechain tap] → [Output]
                                            ↓
                                       [Compressor] → [Output]

### Latency path
Source → LPF (0 samples) → Compressor (64 samples lookahead) → Output
Total: 64 samples

### Issues found
- Parallel path to Output has no latency compensation for the 64-sample compressor delay

Quick reference

PatternWhat to check
Parallel split rejoiningLatency of each branch must match before summing
Sidechain compressorVerify sidechain input is connected and level-matched
Send/return busCheck send gain, return gain, and whether send is pre- or post-fader
Feedback loopConfirm a delay of at least 1 sample exists to break algebraic loop
Multi-rate graphConfirm resampling nodes at every rate boundary

Reviews AudioUnit v2/v3 plugin implementations for spec compliance, thread safety, and correctness. Use when the user asks to review an AudioUnit plugin, check an AUv3 app extension, audit property or parameter handling, or asks "is my AUComponent thread-safe?" or "why does my AU crash in Logic?". Trigger on phrases like "review my AudioUnit", "check my AUv3", "is my render block safe?", or when you see AURenderCallback, internalRenderBlock, kAudioUnitProperty_*, or AUAudioUnit in the code.

Systematic checklist for diagnosing audio artifacts. Use when the user describes a sound quality problem — clicks, pops, crackling, silence, DC offset, aliasing, phase issues, or latency problems. Trigger on phrases like "why do I hear clicks?", "my output has DC offset", "there's aliasing in my oscillator", "phase is wrong in mono", "dropout when CPU spikes". Pairs with audio-dsp-review (realtime safety) and audio-numerics-review (numeric correctness) — use those to fix once the cause is found.

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. Flag issues proactively even when the user hasn't explicitly asked for a review.

Explains DSP math concepts to developers who need the theory behind an algorithm. Use whenever the user asks how a signal-processing concept works, wants intuition behind a formula, or hits a math-shaped bug. Trigger on phrases like "how does a Fourier transform work", "explain z-transforms", "what is convolution", "why does my biquad ring", "what is windowing for", "what causes aliasing", or "how do I convert gain to dB". Also trigger when the user pastes DSP code and asks why it behaves a certain way.

Reviews audio DSP code for numerical correctness. Use when the user asks to review, audit, or check DSP code for correctness issues — filters, feedback loops, fixed-point arithmetic, accumulation loops, or any numeric computation in audio code. Trigger on "check this filter for NaN", "why does my reverb blow up?", "is this numerically stable?", "why do I hear DC in my output?". Pairs with audio-dsp-review (realtime safety); this skill covers numeric correctness. Flag issues proactively.

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.
