This paper introduces a method addressing annotator subjectivity and class imbalance in audio chord estimation (ACE). It proposes a consonance-informed distance metric, consonance-based label smoothing, and a decomposed model estimating root, bass and note activations separately. :contentReference[oaicite:1]{index=1}

ChordSync: Conformer-Based Alignment of Chord Annotations to Music Audio

This website is a collection of resources, tools, and datasets for music research and development. It has been developed in Next.js, and most of the components were developed from scratch. Still a work in progress!
