What it does

...

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

Key Features
<ul><li><strong>Accurate BPM analysis</strong> — powered by <strong>Essentia</strong> for reliable, real-time tempo readings  </li><li><strong>Manual tap tempo</strong> — tap out the BPM by hand when you want to double-check by ear  </li><li><strong>Key analysis</strong> — for harmonic mixing </li><li><strong>Wishlist interaction</strong> — Add single tracks to your Bandcamp wishlist directly from the loaded playlist</li><li><strong>Waveform visualization</strong> — see the shape of a track before you commit to it  </li><li><strong>Extended playlist controls</strong> — smarter navigation to make digging faster and more fun  </li><li><strong>Tempo Adjust</strong> — Change tempo of a track with high quality Key Lock (using <strong>SignalSmith Stretch</strong>)</li></ul>
<strong>BPM handling</strong> is tuned for electronic music ranges to give you the most useful tempo interpretation in practice.  

<strong>Key analysis</strong> 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.

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