video-sound@1.0.7
VERIFIED· install onlyPublisher claims: "Make the sound of any video so it feels real: AI voices that don't sound fake (cast from candidates a person picks, directed with each model's documented tags), dialogue and narration written for the ear with pauses, breaths and small actions, sound effects on the right frame, music planned bar by bar with a quiet part, and a measured mix. Built from 480 sourced findings (Walter Murch, Randy Thom, Ben Burtt, trailer editors, NPR, voice directors, model docs, HyperFrames, earshot) plus paid tests. An agent can't hear, so every step writes numbers: a cue sheet, scripts that build and grade the mix (LUFS, true peak, voice over music, effects within a frame, cuts on the beat, dead air), a voice audition page and an audio LLM judge that shortlists takes. Use for "add sound", "voiceover", "sound design", "music for my video", "make the AI voice sound real", "pick the best take", "SFX", "mix", "launch video audio", "trailer sound", in HyperFrames, Remotion or AI films. Not for making a song as the product." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Nothing executable in the bundle ran; the trace covers the install step only.- Tested

- Not tested

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-13 and scored it 82/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
