What it does

A floating player interface appears on every Bandcamp page — feed, collections, albums, and tracks.

Built for real-world workflows

Whether you're crate-digging, comparing tracks, or building a set by tempo, Bandcamp Deck keeps everything in one place: play, inspect, and evaluate tracks right where you find them.

BPM handling is tuned for electronic music ranges to give you the most useful tempo interpretation in practice.

⚡ Performance note: Analysis speed depends on your internet connection and CPU performance.
