How Fairlight Audio Core handles 2,000 tracks with real-time effects in DaVinci Resolve
DaVinci Resolve Fairlight Audio Core is a scalable audio engine supporting up to 2,000 tracks with real-time effects on a single system. This guide covers distributed processing, the PCIe accelerator card, and managing large track counts.
How does Fairlight Audio Core support large track counts in DaVinci Resolve?
Fairlight Audio Core is a scalable hybrid audio engine that distributes workload across your system's cores, threads, and optional PCIe audio accelerator cards. The combination of DaVinci Resolve with Fairlight Audio Core supports up to 2,000 tracks with real-time effects on a single system. This means sound elements can be split into as many tracks as needed without introducing unwanted latency.

How does distributed processing work in Fairlight Audio Core?
The engine intelligently distributes processing across available hardware resources. For example, it might use the PCIe accelerator card for mixing while the CPU handles plugin processing. This parallel architecture allows Fairlight to maintain low latency even with high track counts and complex plugin chains.
For systems without the PCIe accelerator, Audio Core uses all available CPU cores and threads. Modern multi-core processors handle 500-1,000 tracks with real-time effects using CPU alone. Adding the Fairlight PCIe Audio Accelerator card extends capacity to the full 2,000 tracks with lower latency.
How do you manage large track counts efficiently in Fairlight?
Use audio folders to group related tracks — dialogue, music, effects, Foley — and collapse them when not editing. Folders reduce visual clutter and make navigation faster in projects with hundreds of tracks. Use FlexBus routing to send groups of tracks to sub-mixes, reducing the number of individual tracks feeding the master bus.
For projects exceeding 500 tracks, organize your workflow by category. Keep dialogue tracks in one section of the mixer, music in another, and effects in a third. Use color coding for track headers to identify categories at a glance.
More tracks for complex projects
Pre-edit with Cutsio to tighten your timeline before the mixdown phase. Fewer clips to manage means your track count goes further.
