What it does

...

A floating player interface appears on every Bandcamp page — feed, collections, albums, and tracks. It runs background audio analysis to estimate BPM with high accuracy and Key, so you can evaluate tracks in context without switching tabs or reaching for external tools.

Key Features

Accurate BPM analysis — powered by Essentia for reliable, real-time tempo readings
Manual tap tempo — tap out the BPM by hand when you want to double-check by ear
Key analysis — for harmonic mixing
Wishlist interaction — Add single tracks to your Bandcamp wishlist directly from the loaded playlist
Waveform visualization — see the shape of a track before you commit to it
Extended playlist controls — smarter navigation to make digging faster and more fun
Tempo Adjust — Change tempo of a track with high quality Key Lock (using SignalSmith Stretch)

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

Key analysis is an opt-in feature and not a fully objective measurement. Results will not always be the same as in Rekordbox or Mixed-in-Key.

⚡ Performance note: Analysis speed depends on your internet connection and CPU performance. Disable track pre-loading if you experience problems.
