I'm just stating a worst case. No one would bother analysing a white
noise. But if I analyse speech that contains shhh sounds, or if I analyse
music that has a snare drum, the analyser might have trouble. Even if I
play a chord on a fuzz guitar, as fuzz greatly increases the number of
harmonics, especially if the pre-fuzz signal has low freqs. There are
plenty of interesting signals that contain lots of harmonics.

The hammer is a great analyser. It helps take things apart. I can use it
to analyse sounds. It's easy, I just have to threaten a music student with
it, and the music student will then produce the desired output.
