TTML Lyrics Studio v2.1.0 - WhisperX Alignment & Multi-Track Studio

TTML Lyrics Studio v2.1.0

Highlights & Fixes

• Robust Audio Alignment (Issue #1):
  • Fixed WhisperX alignment audio cutoffs on tracks longer than 5 minutes by using explicit batch chunking and tuned Voice Activity Detection (VAD).
  • Preserved verbatim user lyrics words in word-level and syllable-level alignments, preventing Whisper auto-corrections and hallucinations on regional languages, dialects, and Creole.
  • Added graceful Wav2Vec2 CTC fallback for languages without pre-trained phoneme alignment models.
• Python & CUDA Hardware Compatibility:
  • install.bat now verifies that Python is version 3.10 to 3.13 and blocks unsupported Python 3.14+.
  • Updated PyTorch to CUDA 12.6, providing out-of-the-box hardware acceleration for NVIDIA RTX 20xx, 30xx, 40xx, and 50xx series GPUs.
  • Automatically installs WhisperX in the isolated virtual environment (.venv).
• Dashboard & Autosave Recovery:
  • Recent Projects dashboard with one-click project reopening, recovery from project-bound autosaves, and direct .lrcproj drag-and-drop.
  • Multi-track status overview and album lane previews.
• Studio Documentation:
  • Complete overhaul of the README with high-resolution 1080p workspace screenshots and keyboard shortcut reference guide.
