I’ve created a patch for imms 2.0.2a which allows you to disable the very cpu intensive BPM and frequenzy analyzer feature of imms. On my machine (AMD64 3000+) it takes almost 10 seconds to analyze a single track. While you could still install imms without sox and by
doing so disable this feature you would still need the fftw library installed for no reason. I’ve emailed the patch upstream, so I hope to see it in the next version of imms 🙂
