How MMAudio works

Turn silent AI video generations or descriptive prompts into finished, frame-locked audio tracks in seconds.

Input Video or Prompt

Provide a silent video clip to synchronize Foley against motion cues, or enter a text prompt describing the desired acoustic textures.

Adjust Acoustic Parameters

Set duration between 1 and 30 seconds, select sampling steps, and tune guidance scale to balance prompt fidelity and visual timing.

Export Synchronized Audio

Receive a full-fidelity 44.1kHz audio track or multiplexed video file with transient peaks aligned to on-screen motion.

What MMAudio is good at

A 157M flow matching audio synthesis engine built for frame-accurate Foley and tactile physical soundscapes.

Frame-Accurate Action Foley

Extract visual features at 24 fps to lock acoustic hits and transient peaks precisely onto visual impact frames in silent video clips.

Immersive Environmental Ambience

Generate high-density, multi-layered acoustic beds with natural environmental reverberation, from dripping industrial tunnels to storm-swept coastal winds.

Standalone Text-to-Sound Synthesis

Synthesize crisp physical friction and impact textures without needing video input, ideal for building bespoke SFX libraries directly from text descriptions.

High-Fidelity 44.1kHz Acoustic Output

Deliver clean 44.1kHz audio waveforms that preserve subtle high-frequency details, transient snap, and organic physical decays.

What people build with MMAudio

From film post-production to game asset design, creators rely on MMAudio to add physical acoustic weight to silent visuals.

Cinematic Film and Video Post-Production

Eliminate manual Foley spotting by generating frame-synchronized footsteps, body impacts, and atmospheric beds directly from silent video renders.

Game Sound Design and Asset Generation

Create tactile material sounds, UI feedback hits, and realistic object collision audio for interactive environments without field recording sessions.

Social Media and Short-Form Commercials

Pair social video reels and product showcases with hyper-tactile cooking, unboxing, or mechanical textures that heighten viewer engagement.

Documentary and Archival Media Soundscapes

Construct convincing outdoor and indoor soundscapes with natural acoustic reverberation for background beds in non-fiction media.

E-Commerce and Product Demonstration Video

Synthesize crisp product interaction sounds—like clicking switches, pouring liquids, and opening containers—to give e-commerce video tactile weight.

Frequently Asked Questions

The video-synchronized variant analyzes video frames at 24 fps to align acoustic energy peaks directly with on-screen visual motion, while the text-to-audio variant generates unprompted standalone sound effects and ambient soundscapes purely from your text description without requiring video footage.

Use video-synchronized mode whenever you have rendered silent footage and need exact frame-accurate hits like footsteps or collisions; use text-to-audio mode when building standalone sound libraries, Foley spot effects, or looping room-tone beds.

Yes, MMAudio V2 is the 157-million-parameter compact flow matching architecture developed by researchers at UIUC and Sony AI, built specifically to synthesize 44.1kHz Foley and soundscapes synchronized to video.

MMAudio generates audio tracks from 1 to 30 seconds in duration. It was natively trained on 8-second clips, making 5 to 12 seconds the ideal range for tight visual-to-audio synchronization without timing drift.

MMAudio is engineered for physical Foley and environmental ambience, making it weak at generating coherent human speech, singing vocals, and structured musical scores. For narrative speech or melodic soundtracks, combine MMAudio with dedicated voice or music models.
