Ah I see. It is not uncommon to display complete audio files, much
more than 44100 samples. So all these samples are converted to text
and back to numbers, as they go over the network? (While in the end,
only a couple hundred values are displayed). And every character goes
through the loop in binbuf_text() with all it's cases... well that is
a bottleneck which should not be further aggravated. At least this
performance issue can be quickly tested, using Pd vs Pd-double. I'll
make a test patch for that.
