Settings

LmBox "Settings" (the sidebar and page title just say Settings) is where you configure appearance, notifications, transcoding and local models, audio waveforms, media library behavior, keyboard shortcuts and cache. The gear in the top bar opens Settings; you can also open it from the sidebar via (the route and menu value is setting). Each section is an accordion: click a title to expand it, and only one section stays open at a time.

Theme & appearance

Figure: theme color, day/night mode, interface size, language, simpler top bar and sidebar menu. The screenshot shows the Chinese interface.

Item	Description
Theme color	Click a color circle to switch the brand color
Theme mode	Day mode / Night mode
Interface size	Compact / Standard / Comfortable / Large
Language	For example, English
Simpler top bar	When on, the top bar is more compact
Sidebar menu	Grouped (frequent items collapse into a second level; clicking a first-level item jumps straight to the feature you used last, and hovering still lets you pick another) or Flat (everything listed); click again to customize

Notifications & prompts

Figure: interaction prompt sounds, footer display, system notifications, and webhook / Bark push. The screenshot shows the Chinese interface.

Item	Description
Interaction prompt sounds	Tick whether to play a sound for success / info / question / warning / error
Interaction prompt style	When on, result prompts are pinned to the footer bar (same as global messages)
System notifications	Whether to use system notifications
Webhook	Master switch; add chat-bot webhooks, Bark and similar targets, fill in the request URL, then use Send test

Configure the group bot or push address as described by each platform, and do not share screenshots that show secrets.

Local connections

Figure: nearby-computer discovery, starting LmBox / the Toolkit with the editing app, and external agents with the connection keyword. The screenshot shows the Chinese interface.

Turn on Allow nearby computers to find this one (used by local-network features).

Turn on Open LmBox when the editing app starts (off by default): when it is on, the LmBox extension inside your editing app launches the desktop app automatically on startup.

Turn on Open scaffolding floating toolbar when the editing app starts (off by default): when it is on, the extension also opens the Toolkit floating toolbar on startup (and starts the desktop app too).

External agents (on by default) is a single card: turn the switch on, click the connection keyword to copy a short introduction and prompt, paste it into the chat of an external agent such as Cursor or Claude, and let it run a health check to confirm the connection. Turn it off and no agent can connect.

Footer work tally

Figure: whether to show it in the footer, plus clock-in / clock-out times, refresh interval and text. The screenshot shows the Chinese interface.

A playful "work-hours earnings" readout: set the clock-in / clock-out times, refresh interval, prefix / range earnings / suffix and the off-hours text, then click Save work-hour settings.

External tools & media

Figure: transcoding tool paths, Browse / Check, and Download and install. The screenshot shows the Chinese interface.

Waveforms, some previews and screenshots depend on the transcoding tools on this computer. You can leave the paths empty and let the app find them; if they cannot be found, use Browse to point to them, or use Download and install. After setting them up, click Apply, and use Check to confirm.

You can also follow the step-by-step guide: LmBox desktop install · Configure the transcoding tools.

Local large models

Figure: resource-pack folder, GPU acceleration, and modules such as vocal separation, local subtitles, voice cloning and semantic search. The screenshot shows the Chinese interface.

1. Choose the folder for the resource pack and click Apply
2. When needed, use Download large models to get the whole pack
3. Click Download per module (a green dot means ready); you can turn on GPU acceleration

Common modules: runtime (required), vocal separation, local subtitles, script alignment, background cutout, local voice cloning, sound-effect / shot semantic search and more. They are large, so leave enough disk space.

Audio & waveforms

Figure: playback volume, waveform style with concurrent cache, and automatic sound-name translation. The screenshot shows the Chinese interface.

Options are saved immediately. You can adjust playback volume, list / preview waveform style, generation concurrency, cache count and expiry; you can turn on Auto-translate sound names and choose the extra translation method (such as the official golden key / Keychain). After you open a sound folder, waveforms and translated names finish in the background. See Sound library for details.

Media library

Figure: smaller-thumbnails-first, longest edge and list-preview concurrency. The screenshot shows the Chinese interface.

Item	Description
Prefer smaller thumbnails first	Prefer the preview image format that takes less space
Thumbnail longest edge	Pixel limit (for example 320)
List preview concurrency	How many list previews are generated at once; default 6, up to 16; changes are saved and take effect immediately

Media sidebar

Figure: remember folder, one-branch-at-a-time expand, default width and subfolder scan depth. The screenshot shows the Chinese interface.

Item	Description
Remember last opened folder	Next time you open the media page, go back to the last folder
Expand one folder branch at a time	Expanding one branch collapses the others
Default sidebar width	Width in pixels
Subfolder scan depth	Scan extra sub-levels when opening a folder; 0 lists only the current folder; a larger depth may be slower

Keyboard shortcuts

Figure: the list of global and in-app shortcuts (including audio editing). The screenshot shows the Chinese interface.

Each item is marked Global or In-app. Click a shortcut box to change the key. Common ones include showing the app window, opening search, the Toolkit toolbar, and audio-editing playback / selection. After changing a key, what the app saves is what applies.

Cache & storage

Figure: cache path, choose path, reset, statistics and cleanup. The screenshot shows the Chinese interface.

Use Choose path to move the cache folder, Reset to go back to the default, Cache statistics to see usage, and the trash icon to clean up. Pick a location that is writable on this computer and has enough space.

System permissions (macOS)

Figure: check Full Disk Access, Accessibility, Screen Recording, Microphone and other permissions. The screenshot shows the Chinese interface.

Click Check permissions to view them and jump to System Settings. This section only appears on macOS.

FAQ

Q: Waveforms or previews keep failing?
A: Go to External tools & media, check the transcoding tool paths and click Check; if it still fails, use Download and install and then Apply.

Q: Local subtitles / vocal separation say a model is missing?
A: Open Local large models, confirm the resource-pack path is applied and the module has a green dot; click Download for anything not downloaded yet.

Q: I can't see operation result prompts in the footer?
A: Turn on "Interaction prompt style (pinned to the footer)" in Notifications & prompts, and make sure the related prompt sound / notification switches are not turned off.

Q: Shortcuts do nothing?
A: Check whether the item is Global or In-app; in-app shortcuts need the LmBox window in front. Open Keyboard shortcuts to see whether the key was changed.
