This seems to be correct.
I just found out that once the track has been analyzed I am able to 'Fetch Spectrum'. This is good as I have a workaround for tracks that were not detected at the correct BPM.
Created attachment 17 [details] The defines file I used to compile Distribution: gentoo amd64, desktop profile, bpmdj compiled 64 bit defines file to compile is attached Steps to reproduce: 1. Open a new track from song selector 2. Go to Bpm tab, tap on the tempo and measure the BPM 3. Go to Beatgraph and set a cue point 4. Go to Spectrum tab and click on 'Fetch Spectrum' button Expected: The player will calculate the Spectrum Actual: Nothing happens Repro rate 100% There is no problem if I use an automatic analyzer
