I think I have heard some popping with very fast transients, however.
The compander is quite on the fast side.
The worst case of companding noise reduction I've ever heard was when
I taped myself playing solo jazz guitar on a dBx-equipped cassette
deck. It was the neck pickup of my favorite guitar (a Rickenbacker

like that, right? Well, this recording sounded nothing like the
original performance -- the expanded noise added a little chiff at the
beginning of each note, and with so few highs in the original signal
that chiff was not only distracting, it competely covered up the
original syrupy transient of the guitar.
