Comment 4 for bug 1101281

The vast majority of analysis time is spent in audio decoding and BPM
detection. The waveform calculation is pretty lightweight because it uses
the same decoded audio that goes into BPM detection. It would make the
analysis run faster though, it's just not going to be a massive speed
improvement.
