[MMAudio Multimodal Video Soundscape Directing Blueprint]
Model: ComfyUI-MMAudio / CLIP-ViT Visual Feature Extractor
Input: Silent 4K Generative Video Sequence (Wan / Hunyuan / Kling / MiniMax)
Audio Mode: Synchronized Foley + Diegetic Environmental Ambience (48kHz Stereo)

Acoustic Event Directives & Timestamps:
[0.00s – 1.20s]: Low rumbling subwoofer drone with heavy industrial factory reverberation. Faint metallic clinking in the distant background.
[1.25s]: Sudden crisp mechanical impact as a heavy hydraulic press slams shut; high-pressure pneumatic air hiss release echoing off concrete walls.
[2.40s – 3.80s]: High-frequency sparks scattering across steel floor with realistic crackling sizzle and stereo panning from center to right channel.
[3.85s – 5.00s]: Resonant bass decay settling into quiet ambient room tone with low-end rumble.

Acoustic Quality & Mixing Envelope:
Dynamic Range: Broadcast Standard -14 LUFS integrated
Stereo Width: 120% stereophonic field with realistic acoustic depth
Noise Floor: Zero hiss, studio-grade noise gating on transient decays.

Universal Negative Prompt Constraints:

muffled audio, distorted bass, clipped transients, out-of-sync sound effects, tinny noise, repetitive looping, silent dropouts, synthetic digital buzz.

❓ Frequently Asked Questions (Google Featured Snippet Reference)

How does MMAudio know when an impact occurs in the video?

MMAudio uses a CLIP vision encoder to analyze frame-by-frame visual changes. Sudden shifts in motion vectors trigger corresponding acoustic transients at that exact millisecond.

Can I direct what sounds are generated using a text prompt?

Yes. MMAudio accepts an optional text prompt alongside the video, allowing you to specify exact sound elements like ‘hydraulic press slam, pneumatic hiss, sparks crackle’.

What sample rate does MMAudio produce?

The large model produces 48kHz high-fidelity stereo audio ready for commercial video post-production.
