AniChapters v2.0 — Core Engine Overhaul

What's New

🔧 Audio Matching Engine — Complete Rewrite

The audio matching engine has been fully replaced with a proven, battle-tested algorithm based on Auto Chap v4.2 (librosa + scipy signal correlation).

The previous engine used an NCC-FFT approach via ffmpeg that produced inconsistent results. The new engine uses:

  • librosa for accurate audio loading
  • scipy.signal.correlate for robust cross-correlation matching
  • A silence-prefix padding trick to correctly handle themes that appear at the very start of an episode
  • Parallel OP/ED processing via ThreadPoolExecutor

This results in significantly more accurate OP/ED detection across a wider range of shows.

🗂️ Theme Cache Location

Downloaded themes are now stored in a .themes folder next to your video files, making it easy to find and manage cached themes per series.

🧹 Clear Cache Improvement

The Clear Cache button now properly deletes downloaded theme files (.ogg) in addition to temporary processing files, and displays the total storage freed.

🚫 UI Cleanup

Removed an unnecessary internal log message that appeared during analysis.

Requirements

Make sure to install the new dependencies:

pip install librosa scipy audioread
