Description
PluralEyes is gone. Synfren syncs multicam footage on macOS by the sound the cameras already recorded, then writes a timeline for Final Cut Pro, Premiere Pro or DaVinci Resolve. Every clip says whether it was heard, carried by a camera clock, or needs your eyes - so you only check the ones it points at. macOS 14+, Apple silicon. Your video and audio never leave your Mac.

Could you build this?
No Audio-based multicam synchronization requires complex digital signal processing (cross-correlation, acoustic fingerprinting, drift correction) and exporting native NLE XML/FCPXML timeline formats.
What it would actually take: The core engine requires specialized DSP algorithms in C++ or Swift (using Apple Accelerate/vDSP) to perform high-performance cross-correlation and audio waveform fingerprinting across gigabytes of video audio tracks. In addition to clock-drift compensation, it requires deep understanding of Final Cut Pro XML (FCPXML), Premiere Pro XML, and DaVinci Resolve timeline exchange formats to reconstruct project timelines reliably.
