Not P but DFW: Richterish-looking sound wave

[Mike Jing]

The following excerpt is from David Foster Wallace's *Host*:

NexGen (a Clear Channel product) displays a Richterish-looking sound wave,
of which all different sizes of individual bits can be highlighted and
erased in order to tighten the pacing and compress the sound bite.

It was suggested by a proofreader that the Richter here refers to Gerhard
Richter, a German painter, and the picture of the sound wave displayed by
the NexGen software looks like some of his abstract paintings. I've never
heard of the artist before but it does sound plausible, and the word
"Richterish" is similar to "Picassoesque". Does anyone care to confirm or
refute this?
