Electron tools workspace
Tools in the cloning sidebar or command search opens three utility panes:
- Directorial AI parses direction into instruction, translation hint, rate bias, tokens and taxonomy using the existing direction service.
- Speech-rate fit submits translated text, a positive time slot and target language to the existing fitting service. Invalid durations block submission.
- Probe file submits an absolute path to the existing ffprobe metadata endpoint.
Each operation starts only on explicit submission. Switching tools aborts the frontend request and prevents stale results from replacing another tool's content. LLM-backed operations follow the configured backend routing. Errors stay compact with expandable diagnostics. No new processing engine or network dependency is added.
The tools browser smoke verifies request fields and results with mocked responses. Settings > Audio tools exposes the existing app-managed media bundle installer, status/progress, system-copy selection, restore, and yt-dlp update/restore actions. Downloads start only through an explicit action. Custom executable selection still needs the Electron native path-authorization bridge.
The existing checksummed installer successfully installed ffprobe in the development app data directory. A real probe then read two streams and a four-second duration from an MP4 fixture. No system-wide binary or application version was changed.
Custom FFmpeg/FFprobe executables can be selected from Media tools in the desktop app. The native picker validates the selected executable with -version, then issues the same one-use path capability used by Tauri in the backend-advertised data directory. Cancelling leaves the current tool unchanged. Browser-only sessions do not expose the native picker.
The live Windows conversion smoke now exercises the complete Tools > Convert path with the selected Faster-Whisper and OmniVoice engines: upload, ASR, saved-profile conversion, returned waveform and Vidstack playback-clock advancement. The fixture uses an existing clone profile and does not change the user's engine selections.
Media-tool installation retries temporary filesystem locks for up to four seconds,
including Windows locks after the executable probe. It preserves the existing installation in a sibling backup
until publication succeeds and attempts to restore it if publication fails. If
rollback also fails, the previous installation remains in .media-backup-*/previous;
the error includes that recovery path. Persistent locks surface their original
error; no system binaries or user media are deleted. The same behavior applies to
yt-dlp overlay updates, and restoring the tested version reports failed cleanup.
Dubbing background preservation and long export filter graphs support both legacy
-filter_complex_script and modern FFmpeg -/filter_complex file arguments.
If FFmpeg rejects the legacy option before processing, VoiceStudio retries once
with the modern spelling; filter contents stay in a file to avoid Windows command
line limits. Actual decoding/filter errors are reported without retrying.
