TTML Lyrics Studio v2.1.1

Bug Fixes & Improvements (Issue #2)

• Windows Setup & Batch Scripts (install.bat / start.bat):
  • Resolved a Windows CMD parser issue where unescaped parentheses and delayed expansion caused install.bat to close immediately on certain systems.
  • Restructured install.bat and start.bat with flat goto labels and English console output so errors and status messages always remain visible.
  • Made pip install --upgrade pip non-fatal so Windows file locks on pip.exe never abort the installation.
• One-Click Syllable Scan on Untimed Tracks:
  • Triggering Syllable Scan on untimed lyrics or tracks in the Line Pool now automatically executes the global Line Scan first before running syllable alignment.
• Line Scan & Fuzzy Matching Accuracy:
  • Restored WhisperX default VAD thresholds (0.500 / 0.363) and temperature fallback schedule for reliable vocal phrase detection.
  • Disabled SequenceMatcher autojunk heuristic (autojunk=False) so repeated chorus lines and words are never skipped.
  • Added sliding-window fuzzy similarity matching and boundary expansion so line start/end words are not truncated when slightly misheard by ASR.
• Server & Documentation:
  • Added a 204 No Content route for /favicon.ico to eliminate 404 Not Found console log noise.
  • Added Community & Integrations section in README.md featuring LRC-CheckEdGen (Issue #3).
