AI Voiceover — now audible in preview and baked into exports
AetherCut v1.5.9 shipped on with 5 updates to the private, browser-based video editor. Everything here is already included in the latest version. AetherCut edits on your own device, so your footage never has to be uploaded to a server.
What's new in v1.5.9
- Hidden <audio> element in the preview pipeline syncs voiceover playback with the main timeline (play/pause/seek, drift-corrected)
- Voiceover volume from the Audio panel now controls live playback in real time
- Export pipeline taps the voiceover AudioContext graph via MediaStreamDestination — voiceover is mixed into the exported WebM/MP4
- When a voiceover is present, export automatically uses the MediaRecorder path (WebCodecs can't capture audio elements); pure-video exports keep the faster WebCodecs path
- Known gap: clip-native audio + bgMusic still not included in export — follow-up work
