All questionsDoes the key and BPM finder upload my file anywhere?
No. The file is opened and converted by your own browser, and the result is saved straight to your computer. Nothing is sent to us, so there is nothing for us to keep or delete.
How accurate is it?
It is an estimate, and it works best on songs with a steady beat and clear chords. The usual slips are the relative key (C major and A minor share the same notes) and half or double time, which is why both are shown. A song that changes key gets the key of most of its first 4 minutes.
What is the Camelot code?
A DJ’s shorthand for keys: 8A is A minor and 8B is C major. Keys with the same number, or a number one step away, mix smoothly into each other.
Why does it show no tempo?
When nothing keeps a steady beat, as in a solo voice, ambient music or speech, the finder says so rather than guess. Tap along with the song to count it yourself.
How big a file can the key and BPM finder open?
Up to 1 GB. Long files are fine; the time it takes depends on your computer, since nothing is uploaded. Closing the tab stops it.
