+ | Templates are constructed by taking the median spectrum of sections of audio with chord labels | ||
+ | {{:templates.png?400|templates.png}} | ||
+ | |||
+ | * Each column is a template for a specific chord | ||
+ | * For test songs, compute euclidian distance between all templates and current spectral frame | ||
+ | * Choose best match | ||
+ | * 24.59% accuracy for root only | ||
+ | * Trained on 40 songs, tested on 70 songs | ||
