Audio mixing in HyperFrames
/hyperframes-audio
/hyperframes-audio is a Claude Code skill in the Video & Motion section. It is maintained by heygen-com and published under the Apache-2.0 license. Mixes audio already placed in a composition: fades, volume, ducking music under a voiceover, effects such as EQ or reverb, and multi-track buses.
Author's description
Use when audio already placed in a HyperFrames composition needs to be mixed: fade-in/fade-out, crossfade, track gain or volume, volume automation, ducking, a music bed that fights a voiceover (voiceover carve), effects on a track (EQ, compressor, limiter, gate, saturation, delay, reverb, chorus, phaser, bitcrush), automation envelopes drawn on a track's volume or any effect parameter, or one submix bus carrying a chain, a fader and an automation clock for several tracks at once (`<hf-audio-group>`). Don't use for sourcing or generating audio — finding BGM, SFX, or making a voiceover is `/media-use`. Don't use for clip timing or track layout, which is `/hyperframes-core`.
How to ask for it
