How-to guides for the Mantissa app itself — what each mode does, how its panels are wired together, and the keyboard / mouse shortcuts that aren't obvious. For DSP concepts and a porting walkthrough, see the Tutorials page.

App usage

Getting started

3-minute tour: load two wavs, run wav-diff, read the MLD / MAD / SSNR report. Best first stop after install.

Wave Compare deep-dive (soon)

File loaders, DUT / Span navigation, spectrogram options, the MLD / MAD / SSNR Report panel, and per-curve plot styling.

Debugger workflow (soon)

Pick a Visual Studio / VS Code / GDB session, bind a fixed-point and float pair, watch them update live, auto-suggest Q.

Diag mode end-to-end (soon)

Dump float buffers under GDB, overwrite them in the fixed build, diff the resulting wav — find which buffer is the precision sink.

Configuring per-curve plot styles (soon)

Right-click → Plot Style…: per-role colour / opacity / dash pattern, persisted across sessions.

Keyboard & mouse shortcuts (soon)

Quick-reference card for the modes' most-used hotkeys — Ctrl+L for live, Ctrl+R for refresh, mouse side-buttons for nav, etc.
