Procedural Drawing Sound (Chalk / Marker / Pencil)

Problem:

Whiteboard animations feel unnaturally silent during drawing, and manually syncing sound effects is impractical.

Proposed Solution:

An optional procedural “draw sound” layer that automatically plays while the hand is drawing and pauses when it stops.

• Toggle on/off

• Volume control

• Sound types: chalk, marker, pencil, dry-erase

User Value:

Instant realism, improved viewer engagement, zero setup time.

Business Opportunity:

Low development effort, high perceived polish. Ideal as a one-time or bundled upsell.
