Audio for Video

AI audio generation and processing models specialized for video production — creating sound effects, ambient audio, dialogue, and synchronized audio tracks that bring video content to life. This collection includes audio generation models and video audio merging tools for adding AI-generated audio to video files, SAM Audio Large for audio understanding, and ElevenLabs audio isolation for separating voice from background noise. Adding professional audio is one of the last steps in video post-production, and AI is making it dramatically more accessible: generate a fitting ambient soundscape to match your video's setting, produce synchronized sound effects for actions in the video, add professional voiceover narration, or create custom music beds — all without recording studios or sound libraries. Models in this collection are particularly valuable for creators who generate video content at scale using AI (text-to-video or image-to-video) and need automated audio to match. Audio isolation tools are essential for post-production workflows where clean voice separation is needed before re-mixing. On Segmind, all audio-for-video tools are available as pay-per-use APIs. Chain them with video generation models and TTS in Segmind Workflows to build fully automated, audio-complete video production pipelines.
