How Mirelo SFX works

Turn raw, silent video into fully produced soundscapes in three simple timeline steps.

Upload your silent video

Upload your silent video

Drop in any silent or AI-generated video clip up to 60 seconds with clear on-screen motion.

Set optional material prompt

Set optional material prompt

Add a concise material prompt like crunchy gravel, or leave it blank for autonomous pixel-guided foley.

Render synchronized audio track

Render synchronized audio track

Generate up to four audio variations with spatial reverb and download your synchronized video.

What Mirelo SFX is good at

From pixel-velocity tracking to spatial room acoustics, discover how deep visual analysis powers organic sound effect generation.

Pixel-Velocity Foley Sync

Pixel-Velocity Foley Sync

Directly tracks kinetic boundaries and visual acceleration to map impacts, scrapes, and collisions into frame-locked waveforms without drifting over time.

Spatial Acoustic Modeling

Spatial Acoustic Modeling

Infers visual depth to apply accurate acoustic filters, reverberation, and environmental room tone matched to on-screen geometry.

Material Texture Steering

Material Texture Steering

Direct desired material properties with concise 3-to-6 word cues, steering sound output toward specific textures like crunchy gravel or wet asphalt.

Multi-Sample Variations

Multi-Sample Variations

Generate between 1 and 4 sound-effect variations across clips up to 60 seconds long to audition varied acoustic dynamics before locking your seed.

Frequently Asked Questions

Mirelo SFX 1.6 is designed specifically for generating synchronized foley, spot sound effects, and ambient room tone directly from video footage. It excels at mapping visual velocity—such as footsteps, physical impacts, splashes, and mechanical movements—directly into precise audio waveforms with natural spatial acoustics.

No, Mirelo SFX 1.6 is strictly a sound effects and foley model. It does not generate instrumental music, melodic scores, character speech, or voiceover narration. For background soundtracks or dialogue, pair your footage with dedicated music generators and text-to-speech tools.

Keep text prompts brief and focused strictly on materials or environment details, ideally between three and six words like crunchy gravel or wet concrete. You can also leave the prompt completely empty on your first generation to let pixel-aware tracking generate natural foley autonomously.

The model supports video clips with durations ranging from 1 to 60 seconds, with clips under 10 seconds delivering the tightest synchronization. You can generate between 1 and 4 audio variations per run to audition different acoustic syncs before locking your seed.

Mirelo SFX 1.6 was developed by Mirelo AI, an AI research team based in Tübingen, Germany, and released on May 19, 2026.
