Introducing Timeline Studio Beta + Major Upgrades to Narration, Dialogue & Studio AI Voices

Creators today need more than just great text-to-speech—they need precision, multi-track control, and voices that understand direction. That’s why we’re excited to release one of the biggest updates to Unmixr AI to date, bringing new power to Timeline Studio, Narration Studio, Dialogue Studio, and our new Studio AI Voices (LLM-powered).

Whether you're a YouTuber, podcaster, filmmaker, educator, or audio storyteller, these updates will transform the way you produce content.

⭐ Timeline Studio (Beta): Multi-Track Audio, Video Syncing & MP4 Export

One of the most requested features is finally here—Timeline Studio (Beta) is live!

What’s new in Timeline Studio:

  • Create multi-track audio projects
  • Add TTS clips, uploaded audio, music, and sound effects
  • Sync your project with a reference video
  • Export your final output as MP4 (audio + video)

This means you can now:

  • Produce voiceovers for YouTube videos
  • Build documentary-style narration synced to video
  • Create audiograms, reels, explainers, and product demos
  • Record or import audio and place them on separate tracks for total control

Timeline Studio brings a DAW-like editing experience to the browser—simple, powerful, and built for creators who need fast turnaround.

🎙️ Narration & Dialogue Studio Upgrades: Smoother, Faster & More Intuitive


Both Narration Studio and Dialogue Studio received major improvements to help you create stories, voiceovers, and conversations more smoothly.

What’s improved:

  • Integrated multi-track timelines inside both studios
  • Faster, smoother generation flow
  • Improved stability for long scripts and complex edits
  • Cleaner UI for editing, adjusting, and regenerating audio
  • Better handling of character-based dialogue
  • Improved performance for large projects

Creators asked for more control without complexity—this update delivers exactly that.
