Sound Cues ​

The Sound Cues tab provides a traditional theatrical cue list:

Understanding Cues ​

Each cue entry includes:

FieldDescription
Cue NumberYour custom numbering (Q1, SQ 10, etc.)
SceneWhich scene the cue occurs in
Cue LineThe line or action that triggers the cue
DescriptionWhat the sound is (e.g., "Doorbell rings")
Sound ClipLink to a library clip (optional)
NotesAdditional details

Adding Cues ​

  1. Click "+ Add Cue"
  2. Fill in the cue details
  3. Optionally link to a sound clip from your library
  4. Click Save

AI-Extracted Cues (On-Demand) ​

Sound cues are not auto-extracted during initial script import. Instead, you trigger extraction when ready:

  1. Ensure you've imported a script (see Script Import)
  2. Go to Sound tool → Sound Cues tab
  3. Click "Extract from Script" in the Action Toolbar
  4. AI scans stage directions in your ScriptBlocks for sound cues
  5. A preview dialog shows detected cues with scene links
  6. Select which cues to add (or add all)
  7. Click "Import Selected"
  8. Link actual sound clips to complete each cue

Why on-demand? This approach:

  • Lets you focus on show structure first
  • Provides a dedicated review step for cues
  • Avoids cluttering the initial import
  • Allows re-extraction after ScriptBlock edits

Reordering Cues ​

  • Drag and drop to reorder within a scene
  • Use the sort order field for fine control

Triggering from Cue List ​

  • Click the Play button next to any linked cue
  • The associated sound clip plays immediately

Freesound Integration ​

Freesound.org provides millions of Creative Commons sounds:

Searching Freesound ​

  1. Go to Library tab
  2. Click "Search Freesound"
  3. Enter keywords (e.g., "glass breaking", "crowd murmur")
  4. Results appear with:
    • Preview button
    • Duration
    • License type
    • Download button

Downloading ​

  1. Click Preview to listen before downloading
  2. Click Download to add to your library
  3. The clip downloads and caches locally

License Information ​

Freesound clips are typically:

  • CC0: Public domain, no attribution required
  • CC-BY: Attribution required in credits

On Book Pro tracks license info for each downloaded clip.

Offline Support ​

Sounds work without internet:

How It Works ​

  • Downloaded sounds are cached in your browser's IndexedDB
  • Once cached, clips play even when offline
  • Perfect for venues without reliable WiFi

Storage Considerations ​

  • Sound files can be large
  • Monitor your storage usage in browser settings
  • Clear unused clips to free space

Mic Pack Assignments ​

The Mic Packs sub-tab helps A2s and Stage Managers track wireless mic pack assignments, battery status, and generate swap suggestions when packs are scarce.

Opening Mic Packs ​

  1. Navigate to Sound in the sidebar
  2. Click the Mic Packs sub-tab

Setup ​

  1. Set total packs — Enter the number of wireless packs available for the production
  2. Click "Generate Assignments" — The system assigns packs to mic-eligible actors sorted by first scene appearance
  3. If packs ≥ actors: everyone gets a dedicated pack
  4. If packs < actors: the first N actors get packs, and the swap algorithm runs for the rest

Lock State (Three-Way Cycle) ​

Each assignment has a lock state that you cycle by clicking the lock icon:

StateIconMeaning
NormalStandard assignment — available for sharing via swaps
LockedDedicated pack (e.g., mic sewn into a costume) — never shared
Low Priority⬇Preferred swap candidate — algorithm tries these packs first

Tip: Mark ensemble or minor-role packs as Low Priority to keep principal actors' packs stable.

Minimum Pack Recommendation ​

A recommendation badge shows:

  • Min: X — The absolute minimum packs needed (for rental budgeting)
  • Min: X · Y w/ locks — If you have locked packs, the practical minimum may differ

Click "Use Minimum" to auto-set the pack count to the practical minimum.

Swap Algorithm ​

When packs < actors, the system suggests swaps automatically:

  • Finds actors whose scenes don't overlap with a packed actor's scenes
  • Prefers Low Priority packs first, then normal packs; skips locked packs
  • Generates swap points at scene boundaries
  • Highlights any actors with no available swap window (⚠️)

Managing Swaps ​

  • Accept a swap → Mark as confirmed (✅)
  • Reject a swap → Remove the suggestion
  • Regenerate → Re-run the algorithm (preserves locks)

Scene Matrix ​

After generating assignments, a scrollable grid shows:

  • Rows = Pack numbers
  • Columns = Scenes in show order
  • Cells = Which actor has the pack in each scene
  • Highlighted cells = Swap points (actor changes)

Assignment Table Fields ​

ColumnDescription
Pack #Sequential pack number
ActorThe person wearing the mic
CharactersCharacters played by this actor
LockCycle: Normal → Locked → Low Priority
BatteryCycle: Fresh → Good → Low → Dead
FrequencyRF frequency (editable)
NotesFree text for the A2

Printing the Mic Plot ​

  1. Click Print in the Action Toolbar
  2. Select "Mic Plot" from the report list
  3. The report includes:
    • Assignment Table — Pack #, actor, characters, frequency, notes
    • Scene Matrix — Landscape grid showing who has each pack per scene
    • Swap Summary — All swaps sorted by pack and scene order
