SoundBox stands out in the aescripts library for keeping sound-effect work inside After Effects — previewing, dropping and adjusting SFX from a single panel, with 90 effects included.
SoundBox is a script for After Effects that adds sound effects to projects without manually searching for and dragging audio files. It includes 90 exclusive sound effects — whooshes, hits, clicks, transitions and more — all categorized and ready to drop into any project.
Beyond the included library, you can add your own folders to build custom SFX libraries and turn SoundBox into a central hub for sound design inside After Effects. Sounds can be auditioned, then sent straight to the timeline from the panel with a single click. A playhead-based preview lets you test whole categories of sounds right where your animation is happening, without breaking your timing.
SoundBox also handles smart fades and pans using markers: add in and out fades, stereo pans and timing tweaks that stay easy to adjust later. It's built specifically for motion designers who need fast SFX placement and timing.
SoundBox is best for motion designers who want fast sound-effect placement and timing inside After Effects without digging through folders.
SoundBox is completely free to download and use.
SoundBox supports After Effects 2026, 2025, 2024 and 2023. It runs as a script inside After Effects, letting you preview, drop and adjust sound effects from the panel without leaving the application. If you work across several of these versions, SoundBox covers each of them, and you can confirm the current compatibility details on the developer's page before installing to make sure your specific build is listed.
SoundBox is listed as free in this catalog, but pricing and licensing can change over time. For the current terms, check the developer's page on aescripts before downloading. Once installed, you get 90 exclusive sound effects along with the option to add your own folders as custom SFX libraries, so the tool works with both its bundled sounds and any audio you already own.
SoundBox lets you add your own folders and turn the panel into a central hub for all your sound design inside After Effects. Alongside the 90 exclusive sounds it ships with, your custom SFX libraries appear in the same panel, so you can audition your own files and send them straight to the timeline with a single click, just like the included effects.
SoundBox adds fades and pans using markers, so you can apply in, out and in-out fades, stereo pans and timing tweaks that stay clean and easy to adjust later. It also offers a playhead-based preview for auditioning whole categories of sounds right where your animation is happening, without breaking your timing. These controls sit in the panel alongside the drop-to-timeline workflow, and because the adjustments use markers, revisiting the timing is straightforward.
