SoundBox is an audio workflow script for Adobe After Effects by Eje in Motion. It combines an integrated sound-effects browser with practical audio-editing utilities, allowing motion designers to preview, place and modify SFX without leaving After Effects.

The script also includes 90 exclusive sound effects and supports custom user-created SFX libraries.

• CORE FEATURES

• Integrated SFX browser inside After Effects
• 90 exclusive sound effects included
• Custom SFX library support
• One-click sound placement
• Playhead-based audio preview
• Audio editing and timing utilities
• Audio-to-Keyframes workflow
• Designed specifically for motion-design workflows

• INCLUDED SOUND EFFECTS

SoundBox includes:

• 90 exclusive SFX

The official page specifically mentions categories such as:

• Whooshes
• Hits
• Clicks
• Transitions
• Additional categorized effects

The product page does not publish a complete item-by-item inventory of all 90 sounds.

• CUSTOM SFX LIBRARIES

SoundBox is not limited to the included sounds.

Users can:

• Add their own SFX folders
• Create custom sound packs
• Organize personal sound libraries
• Access those libraries directly inside After Effects

This allows SoundBox to function as a centralized sound-design hub rather than only as a fixed 90-sound pack.

• AUDIO PREVIEW WORKFLOW

Sounds can be auditioned directly from the SoundBox panel.

The workflow supports:

• Previewing individual sounds
• Browsing categorized SFX
• Previewing complete categories
• Listening relative to the current playhead position
• Sending selected sounds directly to the timeline

This reduces the need to repeatedly browse external folders and manually drag audio files into After Effects.

• AUDIO UTILITIES

SoundBox combines several audio-processing and timing tools in one panel:

• Reverse
• Delay
• Modulator
• Stereo Panning
• Fade In
• Fade Out
• Fade In / Out
• Volume Nudges
• Volume Step Controls
• Audio to Keyframes

• PANNING TOOLS

The script supports stereo movement such as:

• Left → Right
• Right → Left

Pans can be managed with markers, helping keep timing adjustments visible and editable in the composition.

• SMART FADES

SoundBox includes marker-based fade controls for:

• Fade In
• Fade Out
• Fade In + Out

These tools are intended to simplify common audio cleanup and transition tasks directly inside After Effects.

• REVERSE & TIMING TOOLS

Audio can be reversed directly through the SoundBox panel.

The workflow also includes transition markers and timing controls for aligning sound effects more precisely with animation.

• DELAY & MODULATOR

SoundBox includes Delay and Modulator tools for adding variation and space to sounds without requiring a separate workflow outside the panel.

These tools can be useful for:

• Stylized transitions
• Repeated effects
• Motion accents
• Experimental sound design

• AUDIO TO KEYFRAMES

SoundBox includes an improved Audio-to-Keyframes workflow.

This allows audio amplitude information to drive animation properties, making it useful for:

• Music-reactive animation
• Sound-reactive motion graphics
• Beat-driven effects
• Audio-synchronized visual elements

• MOTION DESIGN WORKFLOW

The script is specifically designed for fast SFX placement and timing in motion-design projects.

Typical workflow:

• Preview a sound
• Place it at the current timeline position
• Adjust volume
• Add fades
• Pan the sound
• Reverse or modify timing when needed
• Convert audio information to keyframes for reactive animation
