SubSync 1.0.2 (fork) · Tag: v1.0.2

A modernized fork of sc0ty/subsync by Michał Szymaniak.

This release makes the per-subtitle (piecewise) sync mode introduced in 1.0.1 actually reliable, and puts its controls in your hands.

What's new in 1.0.2

• Piecewise sync no longer chases noise. Correlation points are individually noisy (a mismatched word can be off by a second), and the old warp retimed every line to the local median of a few of them — injecting a spurious sub-second wobble on top of the correct timing. It now anchors on the global linear fit and applies a local correction only where the nearby points are dense and significantly, consistently off that line (a real cut/ad-break/mid-file resync), shrinking everything else back to the line. On a real test file this cut the lines landing more than 0.5s off from 46% to 13%, while still following genuine resyncs.
• Tunable from the GUI. Settings → Synchronization now exposes Piecewise window (s), Piecewise min local points, and Piecewise significance (σ), each with an info tooltip. Higher significance stays closer to a plain linear sync; lower follows the points more eagerly.
• Piecewise in batch processing. The batch window has a new "Sync method" dropdown (Linear / Per-subtitle piecewise).

SubSync 1.0.1 (fork)

A modernized fork of sc0ty/subsync by Michał Szymaniak.

What's new in this fork

• PocketSphinx 5.x — speech recognition ported from the removed sphinxbase/PocketSphinx API to a maintained release (endpointer-based VAD).
• FFmpeg 6.x support.
• New "per-subtitle (piecewise)" sync mode — warps timing per subtitle from the correlation points, fixing non-linear drift (cut scenes, ad breaks, mid-file resyncs) that a single offset+speed line can't. Selectable in the GUI ("Sync method") and CLI (--sync-mode piecewise).
• wxPython 4.2 compatibility fixes.

Downloads

• subsync-1.0.1-portable-amd64.exe — portable, no install (keeps config/models next to itself).
• subsync-1.0.1-amd64.msi — installer (Start-menu shortcut + uninstaller).
