v0.3 (build 5)

Current stable release

1 November 2026

BWF time-of-day fix: cut-segment BWF files now write the segment's true time-of-day to both bext and iXML, so imported segments line up correctly in your DAW.
Lower memory on long jobs: WAV and BWF work uses less peak memory, and stamped BWF files are written through a temporary file and published atomically.
Licence revalidation: active licences are checked with the licensing service at most once every 24 hours. Revoked, deleted or inactive licences lock the app; a network failure keeps the last locally verified licence.
Stable device identity: the app keeps a device-identity mirror in Application Support, so deleting only the Keychain item does not reset a trial or orphan an activation.
Third-party notices: available from Help, with the full Sparkle, pyaaf2, CPython and python-build-standalone licence texts. The private Python runtime no longer ships pip or bytecode caches.
Cleaner download: the release archive is free of AppleDouble metadata, caches, bytecode and .DS_Store files.
Includes optional AAF audio alignment, first shipped in build 4. Read the alignment guide.

Previous stable release

28 October 2026

Optional AAF audio alignment: find one fixed offset between an AAF and Stereo mix WAV exported from the same edit with different in points. Camera scratch audio can match a final mix when enough sound is shared.
Earlier alignment feedback: see the offset and confidence as soon as matching finishes during the input scan. The summary remains visible through Mapping, Validate and Report.
Manual control: adjust an automatic result or enter a manual offset. Uncertain matches keep the current alignment and add a warning; automatic matching remains off by default.
Matching in points: retain leading mix audio or trim AAF material before the WAV start, advancing crossing audio and picture source ranges together.
AAF importer packaging: keep the bundled Python standard library intact when resources are refreshed during an incremental build.
Audio matching runs locally and leaves source files unchanged. Read the alignment guide for setup, confidence, manual offsets and limitations.

Timecode Stamping: stamp bext and iXML start timecode from LTC without modifying audio samples.
Single and Grouped Batch: stamp one synchronised WAV set, or use Filename token or Regular expression matching to stamp grouped takes.
LTC Cut Splitter: detect LTC discontinuities and split a music WAV into timecode-stamped segments.
PolyWAV Splitter: split multichannel WAVs to mono, in linear PCM or 32-bit float, without re-encoding.
Timeline Builder: rebuild a multicam timeline from Timeline XML or chased-timecode AAF, a Synced audio folder and a Stereo mix WAV, and write FCPXML.
Build readiness validation, a readable build report, and CSV reports for post-run review.
Supported LTC frame rates: 23.976, 24, 25, 29.97 NDF, 29.97 DF and 30; Double LTC handles 50/60 fps picture.
Audio files are never uploaded. Licensing requests send a pseudonymous Keychain device identifier, your Mac’s sharing name and your licence key.
14-day full-featured trial and a one-time lifetime licence with 2 Mac activations and free updates through the v1.x lifecycle.
Universal build for Apple silicon and Intel, requiring macOS 14.6 or later. Distributed as a ZIP download (~47.8 MB).
Documentation hub covering installation, trial, activation, Timecode Stamping, LTC Cut Splitter, PolyWAV Splitter, Timeline Builder and troubleshooting.
