LyricsEditor v0.0.9

v0.0.9

Full Changelog: v0.0.8...v0.0.9

• Parentheses Background Vocal Sync Fix: Resolved an issue where adding or removing parentheses ( ) in the Edit Text modal did not update the background vocal role (x-bg) on the timeline track when words matched identical or LCS tokens.
• Isolated Row Drag Boundaries: Drag boundaries and sibling interactions are now isolated between main vocals and background vocals. Adjusting background vocal blocks no longer bumps into or is constrained by main vocal blocks, allowing them to freely overlap.
• Improved Multi-Row Overlap Editing: Any track containing both main and background vocal words now automatically displays in double rows when hovered or dragged (regardless of whether they already overlap), giving users the immediate visual space to align overlapping parts.

---

• If "Keep Word Timings" is UNCHECKED (Default): Swopping words will cause them to carry their custom durations to their new positions (e.g. one retains its original duration at its new place).
• If "Keep Word Timings" is CHECKED: Swapping words will keep the timeline slots completely static, only swapping the text labels at their respective slot indices.

LyricsEditor v0.0.8

What's New

Full Changelog: v0.0.7...v0.0.8

• Integrated Metadata Editor: Added a tag editor popup under the Tools dropdown. Allows editing global parameters (Title, Artist, Album, Language, Creator, Lyricist, Copyright, iTunes Timing Mode, Leading Silence, Agent list, and Songwriters).
• ID3 Tag & Lyrics Metadata Extraction: Supports extracting ID3v2 tags directly from loaded audio files (or using filename heuristics) and extracting lyrics headers from loaded LRC/TTML files. Includes a confirmation check to prevent accidental overwrites.
• Apple Music / iTunes TTML Support: Adds export options for Apple TTML (iTunes) and Apple TTML (Words) Karaoke, including songwriters metadata, agents definitions, and segment groupings.
• Interactive Multi-Row Overlap Layout: Resolves timing overlap editing blocks. Sequential words layout on one row, but overlapping main and background vocal blocks dynamically split into double rows on hover or drag to make editing boundary timestamps simple.
• Parentheses-Based Background Vocal Input: Typing words inside parentheses ( ) in the Edit Text modal automatically flags them as background vocals (ttm:role="x-bg").
• Line Attributes dialog: Added a tag icon button on timeline tracks to customize song parts (itunes:song-part) and vocal agents (ttm:agent). Includes option to automatically propagate parts to subsequent lines.
• Symmetrical Track Indicators: Redesigned left-hand track-info and right-hand track-end-time layouts into stacked double rows. Displays vocal agent and song part badges on the left, balanced by a purple BG indicator badge on the right, keeping layouts symmetrical and highly readable on narrow or portrait viewports.
• Bidirectional JSON Support: Fully exports and imports comprehensive song metadata (title, artist, album, language, agents list, songwriters, and duration) alongside explicit cue/word properties (vocal agents, song parts, background vocal roles, and exact timing ranges).

LyricsEditor v0.0.7

What's New

Full Changelog: v0.0.6...v0.0.7

• In-Browser AIFF Audio Support: Adds full client-side decoding and conversion of AIFF (.aif, .aiff) audio files.
  • Custom binary parser manually extracts AIFF FORM, COMM, and SSND chunks.
  • Supports converting 8-bit, 16-bit, 24-bit, and 32-bit big-endian PCM samples into standard 16-bit little-endian WAV format on the fly.
  • Decodes 80-bit IEEE 754 extended precision float structures for accurate sample rate conversion.
  • Enables natively unsupported AIFF files to play seamlessly and render precise waveforms.
• Improved Media Accessibility: Integrated .aif and .aiff file formats into the standard audio file inputs and drag-and-drop workspace detectors.
• Responsive Layout Optimization: Configured #btn-hotfix to hide its text label and transition to icon-only mode on medium screens (under 1280px), maximizing toolbar layout efficiency.
• Clean Source Formatting: Replaced corrupted separator characters (──) in code comments with clean, standardized comment formatting for improved code readability.

LyricsEditor v0.0.6

🌟 What's New

Full Changelog: v.0.0.5...v0.0.6

• Full Undo/Redo Session Persistence: The entire multi-step undo/redo history stack (history) and current pointer index (histIdx) are now securely serialized and persisted in localStorage alongside your session. Refreshing (F5) or reloading the page no longer wipes out your undo/redo history, letting you step back and forth through your changes seamlessly!
• Punctuation-Only Word-Block Merger: Solves the issue of floating punctuation word-blocks (like . or ,) by automatically merging them into their preceding word blocks (appending the text and extending the duration). This cleans up the alignment pool and prevents timing gaps or syllable-shift conflicts.
• Smart Tag-Aware Alignment: Automatically isolates bracketed or parenthesized tags (like [Music], (Instrumental)) in the primary timeline during alignment. Skipped tags keep their exact original timings and are neatly converted into clean timeline empty lines, ensuring they never shift or pull subsequent lyric words out of sync.
• Powerhouse Combined Smart Merge & Replace Tool: Added the "Smart Merge + Replace Text" tool to the global list, combining structural alignment of AI line breaks with advanced reference-based text replacement.
• Overlap-Free Timeline Structure: Updated both standard and combined reference-based merge engines to ignore empty reference lines, completely preventing redundant timing overlaps and keeping your editor layout perfectly compact.
• Direct Toolbar Shortcuts: Added a new direct-access shortcut button for Smart Replace Text in the header toolbar. Featuring a responsive desktop-only design, it automatically adjusts for tablet and mobile views.

• Shortcuts Refinement: Reassigned core shortcuts for better mnemonics (e.g., P for Fullscreen, O for sOOOOOng loop) and added keyboard shortcut tips to the initial placeholder screen.
• UI Polishing: Redesigned numeric input controls in modals to remove browser default spin buttons, replacing them with a custom premium vertical UI.
• Comprehensive Gap Filling: Expanded the gap-filling suite with "Fill Gap to Start of Audio" and "Fill All Gaps" (Start, Middle, and End). These tools ensure your lyrics cover the entire audio timeline perfectly, preventing unintended "blank screens" during playback.
• Audacity Labels Power-Suite: Full support for importing and exporting Audacity Label formats. Includes a specialized Word-Level Export mode that generates individual labels for every word in the timeline.
• Advanced Multi-Segment Import: Automatically detects multiple tracks or segments within VTT, SRT, and Audacity Labels files. New modal allows selecting specific tracks, joining all, or using Smart Import.
• Manual Smart Import (Integrated Smart Merge): Manually pick your "Primary" timing track and "Reference" phrasing track from a single multi-segment file. This feature leverages the Smart Merge logic to automatically fix AI-generated line breaks by realigning word timings to your preferred structure, featuring line-count validation and similarity checks.
• Real-Time Audio Waveform Background: Added professional-grade audio waveform visualization behind every line in the timeline. Features symmetric peaks, auto-normalization, and layout-safe rendering for high-precision synchronization.
• Intelligent Blank-Word Management:
  • Auto-Conversion: Empty lines automatically become "Ghost" blocks when merged into other lines to preserve silence.
  • Smart Normalization: Lines containing only blank words automatically revert to clean [Empty] placeholders after structural operations.
• Advanced Timeline Integrity Tools:
  • Upgraded Hot Fix: A one-click solution that now resolves word overlaps, fills timing gaps, and cleans up whitespace in a single pass.
  • Fix Jumps (Push Sequential): A new cascading shift tool that resolves line collisions by pushing subsequent lines forward, preserving original durations and phrasing.
  • Strict LRC Parsing: The engine now strictly enforces line boundaries during import, automatically clamping word timestamps to prevent "backward jumps."
• Edit Modal Enhancements:
  • Smarter Deletion: Deleting words or placeholders (\) in the text modal now automatically merges their duration into the preceding word to fill the gap.
  • Partial Joining: The "Join Words" tool now supports selected text ranges for granular syllable merging.
  • Refined Blank Removal: The "Remove Blanks" tool now rejoins syllables perfectly without leaving orphaned spaces.
  • Improved Tokenization: Special symbols (\, ") are now treated as independent tokens even when attached to words, preventing accidental word merging.
• UI/UX Refinements:
  • Scroll Preservation: Maintains scroll position during all structural operations (merge, split, edit).
  • Muted Ghost Visuals: Blank blocks now feature a muted background with a backdrop blur to make the background waveform less distracting.
• Performance Optimization: Waveform caching and 60fps rendering ensure a lag-free experience even on low-end devices.
