# audio-flac-quality-check-tauri Tauri 2 desktop port of [`audio-flac-quality-check`](https://github.com/xjmzx/audio-flac-quality-check). Same heuristic, same thresholds, same workflow — different stack so it matches the rest of the suite ([`smpl-tool`](https://github.com/xjmzx/smpl-tool), [`ndisc`](https://github.com/xjmzx/ndisc), [`bpm-tapper`](https://github.com/xjmzx/bpm-tapper)). **Stack:** Tauri 2 desktop binary + React 19 + TypeScript + Tailwind v3. Frontend is Vite. Scanning runs in Rust commands that shell out to `ffmpeg`/`ffprobe` in parallel via rayon. ## What it does For each `.flac` file under a chosen root: | Verdict | Peak above 16 kHz | | --- | --- | | `LOSSLESS` | ≥ −35 dB | | `UNCERTAIN` | between (review manually — quiet/ambient genuine lossless can land here) | | `PROBABLY-LOSSY` | ≤ −65 dB | | `NOT-FLAC` | codec is not flac | | `UNKNOWN` | ffprobe / ffmpeg failed | The method does **not** rely on file size or compression ratio — those cannot distinguish real lossless from a lossy source re-encoded as FLAC. ## Install runtime dependencies (Debian / Ubuntu) The app shells out to `ffmpeg`/`ffprobe` — same runtime dep as the Python original. sudo apt update sudo apt install ffmpeg Tauri's [Linux prerequisites](https://tauri.app/start/prerequisites/#linux): sudo apt install \ libwebkit2gtk-4.1-dev \ libgtk-3-dev \ libayatana-appindicator3-dev \ librsvg2-dev \ libssl-dev \ build-essential \ curl wget file Plus a Node toolchain and a Rust toolchain: sudo apt install nodejs npm curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh ## Quick start git clone https://github.com/xjmzx/audio-flac-quality-check-tauri.git cd audio-flac-quality-check-tauri make deps # npm install + cargo fetch make icons # one-time: generate Tauri bundle icons from icon.svg make dev # opens the Tauri window with hot reload ## Build / install / deploy The `Makefile` builds a release binary and places it under `PREFIX/bin`, the icon under `PREFIX/share/icons/hicolor/scalable/apps`, and a `.desktop` entry under `PREFIX/share/applications` (so the app appears in GNOME / KDE / XFCE app menus as **FLAC Library Browser**). # user-level install (no sudo) — default PREFIX is $HOME/.local make install # system-wide sudo make install PREFIX=/usr/local # remove make uninstall # or: sudo make uninstall PREFIX=/usr/local Other targets: make help # list everything make check # tsc + vite build + cargo check (no full Tauri build) make build # release build only make clean # remove dist/ and src-tauri/target/ ## Keybindings (matches the Python Tk version) | Key | Action | | --- | --- | | `Ctrl+R` | Re-scan the configured root | | `Ctrl+F` | Focus the search box | | `Esc` | Clear filter + search | | Double-click a track row | Open its containing folder (`xdg-open`) | ## Persistence Scan reports are cached as JSON in the standard Tauri app-data dir (`~/.local/share/uk.fizx.audioflacqualitycheck/last_scan.json` on Linux), not next to the binary. The window restores the last scan on launch. ## Layout audio-flac-quality-check-tauri/ ├── src/ # React + TS frontend │ ├── App.tsx # main layout │ ├── components/ # ScannerControls, Filters, LibraryTree, │ │ # StatusBar, NostrPanel (stub), Section │ ├── lib/cn.ts # clsx + tailwind-merge helper │ └── lib/tauri.ts # typed wrappers around invoke() + events ├── src-tauri/ │ ├── src/lib.rs # scan_library / load_report / │ │ # save_report / open_folder │ ├── Cargo.toml │ └── tauri.conf.json ├── icon.svg # suite-style 128px tile ├── audio-flac-quality-check-tauri.desktop.in └── Makefile ## Notes on the Nostr slot The right-hand `NostrPanel` is a structural placeholder, matching the suite-wide layout used in `smpl-tool` and `ndisc`. Nothing is wired — the quality scanner has no obvious thing to publish yet. When a use case appears (e.g. publish a library-quality summary, or share a suspect-track list), copy `lib/nostr.ts` and the upload + publish flow from [`smpl-tool`](https://github.com/xjmzx/smpl-tool/blob/main/src/lib/nostr.ts). ## Caveats Spectral cutoff is a heuristic; pure drone / sub-bass / silent ambient tracks have no high-frequency content even when fully lossless and will show up as `PROBABLY-LOSSY`. Verify suspect tracks by listening, by checking metadata (encoder, source bitrate), or with a spectrum visualiser like Spek. ## Companion projects - [`audio-flac-quality-check`](https://github.com/xjmzx/audio-flac-quality-check) — the original Python + Tk version this is a port of. - [`smpl-tool`](https://github.com/xjmzx/smpl-tool) - [`ndisc`](https://github.com/xjmzx/ndisc) - [`bpm-tapper`](https://github.com/xjmzx/bpm-tapper)
