Design¶

Architecture decisions, API contracts, and the algorithm rationale behind shipped features — for anyone who wants the "why" and "how it works" underneath a feature they're already using, not just contributors. (Repo layout and forward-looking roadmaps live under Contributing instead.)

• API Taxonomy — the DSP building-block hierarchy and its naming axis, plus concrete rename proposals
• Quantization — fixed-point pipeline design
• Measurement Suite — tone, NPR, and IMD metric internals
• DSSS Acquisition — stateless, parallel, dynamics-capable acquisition architecture + roadmap
• Corr2D Interpolated Inverse — decoupled, pffft-friendly inverse FFT size + free sub-bin interpolation
• Spectral & Measurement API Map — module dependency graph
• Waveform Amplitude & Composition — level/power conventions for wfmgen
