How to Get Best Results
🎯 Best Input
- ✓Clean recordings with clear harmony (piano, guitar, etc.)
- ✓Pop, rock, jazz, and folk songs with standard chord progressions
- ✓Isolated instrument stems (from Stem Separator) for highest accuracy
⚠️ Less Ideal
- ✗Heavy electronic/EDM with synthesized sounds
- ✗Drum-heavy tracks without clear pitch content
- ✗Complex orchestral arrangements with many layers
💡 Pro Tips: Use the Stem Separator to isolate the harmonic instruments first, then analyze that stem for much higher chord accuracy!
