Sound Prompter is an AI-powered sound generation plugin developed by Blace Plugins for Adobe After Effects and Premiere Pro. It analyzes video footage or text descriptions to generate matching sound effects and music, streamlining the sound design workflow.

All processing runs locally using the blace.ai engine, without uploading footage or prompts to external servers.
