A comprehensive set of tools for analyzing and optimizing your Traktor DJ library. This suite includes a powerful library analyzer and a precision cue alignment tool.
Generates a comprehensive HTML report of your Traktor collection with interactive analytics, insights, and actionable recommendations for library optimization.
Aligns all cues in your Traktor NML file to the AutoGrid with 5ms precision, ensuring perfect beat synchronization for seamless mixing.
The analyzer provides deep insights into your Traktor collection:
- 📊 Interactive Analytics: Genre distribution, BPM analysis, key distribution, quality metrics
- 🎯 Smart Insights: Identifies tracks needing attention (missing genres, poor quality, alignment issues)
- 📈 Visual Charts: Beautiful Chart.js visualizations of your library statistics
- 🔧 Actionable Reports: Click insights to see specific tracks that need fixes
- ⚡ Library Tools: Built-in button to run cue alignment directly from the web interface
- 📱 Responsive Design: Works perfectly on desktop and mobile browsers
- Cue Point Analysis: Well-cued (6+ cues), moderately cued (3-5 cues), poorly cued (≤2 cues)
- Quality Assessment: Audio quality analysis with bitrate and format detection
- Alignment Detection: Identifies tracks with misaligned cues (5ms precision)
- Missing Data Detection: Finds tracks without genres, keys, or proper metadata
- Interactive Filtering: Click any insight to see the specific tracks involved
- Professional Reporting: Clean, modern HTML interface with export capabilities

The alignment tool analyzes each track in your Traktor collection and:
- Finds the AutoGrid cue and extracts the BPM information
- Calculates the nearest beat position for each hot cue
- Updates cue positions to align with the musical grid (5ms precision)
- Preserves the original file and creates a new aligned version
python3 align_cues_to_autogrid.py collection.nmlThis creates collection_aligned.nml with all cues aligned to the AutoGrid.
python3 align_cues_to_autogrid.py collection.nml my_aligned_collection.nmlpython3 align_cues_to_autogrid.py --help- Parses the NML file: Reads the XML structure of your Traktor collection
- Finds AutoGrid: For each track, locates the AutoGrid cue and extracts BPM and start time
- Calculates beat positions: Uses the formula
beat_duration = 60.0 / BPMto determine beat spacing - Aligns cues: Finds the nearest beat position for each hot cue and updates its position
- Preserves originals: Only updates cues that are more than 5ms off the grid to avoid unnecessary changes

📊 Analyze First: Run the analyzer to get comprehensive insights
python3 traktor_library_analyzer.py collection.nml
-
🔍 Review Issues: Open the HTML report and click through insights to identify problems
-
⚡ Fix Alignment: Use the built-in "Align Cues" button or run manually:
python3 align_cues_to_autogrid.py collection.nml collection_fixed.nml
-
✅ Verify Results: Re-analyze the aligned collection to confirm improvements
- 🎯 Cue Standards: Aim for 6+ cues per track for optimal DJ performance
- 🔧 Fix Priorities: Address poorly cued tracks first, then quality and metadata issues
- ⚡ Precision Mixing: 5ms alignment tolerance ensures beat-perfect transitions
- 📈 Regular Analysis: Run monthly analysis to maintain library health
- Time Complexity: O(n) linear processing of tracks
- Memory Usage: Efficient streaming parser for large collections
- Output Format: Modern responsive HTML with Chart.js visualizations
- Data Processing: Comprehensive metadata extraction and statistical analysis
- Precision: 5ms alignment tolerance for professional mixing
- Time Format: Handles Traktor's mixed time formats (AutoGrid in seconds, cues in milliseconds)
- Beat Calculation: Standard musical timing:
beat_duration = 60.0 / BPM - Grid Reference: Uses AutoGrid BPM when available, falls back to track BPM
- Safety: Only processes tracks with valid AutoGrid cues
- 🔒 Backup First: Always keep a backup of your original NML file
- 🎵 AutoGrid Required: Tracks without AutoGrid cues will be skipped in alignment
- 📊 Analysis Safe: The analyzer only reads your collection (no modifications)
- ⚡ Precision Focus: 5ms alignment tolerance balances accuracy with musical feel
- 🔄 Verification: Both tools use identical logic for perfect consistency
The track needs to be analyzed in Traktor first to create the AutoGrid.
Verify your NML file isn't corrupted by opening it in Traktor.
This indicates a bug - both tools should show consistent results. Please report this issue.
Ensure you're opening the HTML file in a modern web browser with JavaScript enabled.
