AutomixIQ
Overview
AutomixIQ is Tuned Global's AI-driven music mixing technology, originally developed by Pacemaker and now available as an SDK for any music streaming application. It analyses beats, loudness, vocals, and tempo to create seamless transitions between tracks — producing a continuous, professional DJ-like listening experience without creating derivative musical works.
AutomixIQ is delivered as a native SDK for Android and iOS.
What AutomixIQ Does
Unlike standard crossfades that simply overlap the end of one track with the start of the next, AutomixIQ intelligently mixes songs by analysing their musical properties:
- Beat matching — Aligns beats between outgoing and incoming tracks
- Tempo analysis — Adjusts transitions based on BPM differences
- Loudness normalisation — Ensures consistent volume across transitions
- Vocal detection — Avoids clashing vocals during the transition window
- Live mixing — Transitions are generated in real time during playback, never pre-rendered or saved
The result is a gapless, musically coherent listening experience that keeps users engaged for longer sessions.
Why It Matters
| Challenge | How AutomixIQ Solves It |
|---|---|
| Gaps between songs | Eliminates silence and abrupt changes that prompt users to stop listening |
| Jarring crossfades | Intelligent transitions maintain mood and rhythm across different tempos and keys |
| Competitive differentiation | A premium feature that most streaming services don't offer |
| Paid tier conversion | High-quality mixes give free users a reason to upgrade — mixes are hugely popular on YouTube but typically require professional DJ skills |
In a blind Turing test comparing AutomixIQ mixes to those by Steve Aoki using the same tracks, results were nearly indistinguishable — AutomixIQ scored within 1% of a professional DJ on transition quality.
AutomixIQ Studio
With Studio enabled, end users can interactively edit transitions:
- Adjust fade in/out points
- Zoom into transition regions
- Control volume curves
- Fine-tune the mix to their preference
This turns passive playlist listening into an active, creative experience — users become DJs of their own playlists.
Architecture
AutomixIQ is an SDK-based integration, not a REST API. The SDK handles:
- Real-time audio analysis of each track
- Transition computation and playback
- Optional Studio UI for user-editable transitions
- Integration with any music catalogue (not limited to Tuned Global)
The mixing happens live on the device during playback. No derivative audio files are created, stored, or transmitted.
Catalogue and Licensing
AutomixIQ is designed to be rightsholder-friendly:
- Uses only the licensed tracks already available in your streaming service
- Transitions are computed and played live — never saved to the device or recorded
- Does not create derivative musical works, eliminating remixing-related licensing issues
- Built on Pacemaker's patented technology with proven licensing compliance
Searching the Catalogue
AutomixIQ works with playlists — users select or build a playlist, and AutomixIQ handles the transitions. To power playlist discovery and track selection, integrate with Tuned Global's Metadata API.
