Native Mac Audio Assistant

LTC chaos to clean timelines. Fast.

LTC Magic turns LTC chaos into clean timelines fast: it embeds timecode, detects LTC jumps, and builds DaVinci Resolve timelines from your audio and XML, saving hours of manual conforming.

Stop fighting import offsets.

Make every stem report the same clock the mix heard. Broadcast WAV–ready PCM workflows built directly into your Mac.

Byte-for-Byte Preservation

We stamp proper start timecode into outputs (including bext and iXML) while keeping the audio samples unchanged. You're not re-rendering the sound, you're fixing how NLEs interpret it.

Flexible Batching

Match stems via name tokens, regex patterns, or utilize LTC cut detection for segmenting discontinuities.

// Regex Match Group
(A[1-9])_.*?_STEM\.wav

Pro Timecode Support

Common frame rates locked in. Every batch generates a detailed CSV log for post supervisors to audit.

Automated Audit Trails

A comprehensive CSV log is generated after every run, establishing unshakeable traceability for post teams.

Bridge Resolve
and Final Cut Pro.

Don't become a human XML parser. Take a source XML from Resolve, a stereo mix, and a folder of synced audio, and auto-generate an editor-ready FCPXML with zero guesswork.

01

Inputs & Mapping

Provide the Resolve XML, your stereo bounce, and your pile of synced WAV stems.

02

Pre-Flight Validation

LTC Magic rapidly checks track layout, duration boundaries, and reports gaps automatically before generating.

Rebuild FCPXML

Get a perfect timeline with preview rows and a clean post-build report outlining any anomalies.

Polywav Splitter

One multichannel WAV in, one mono WAV per channel out. LTC Magic demuxes the file directly, so you keep the same PCM quality end to end with no re-encoding step.
