Visualisers look bad when VisualNode's length is < 512

I honestly don't know if this is a bug or a problem with the audio streams from various shoutcast streams.

The end result is, that eg. the StereoScope and MonoScope visualisers only visualise on a 1/4th of their line, the rest is just flatline.

I traced it down to the VisualNode passed from AudioOutput having a length of 128, where most of the visualisers expect 512. BumpScope? seemed to work around it, but the rest looked pretty bad.

I'll attach a sample file (from SomaFM shoutcast, it might playback with strange noises every 1/2 second because of meta info) and a patch. The patch fixes it in two ways

  • it makes StereoScope, MonoScope and Goom work by duplicating bytes, just like BumpScope
  • make MainVisual: :add also do the replication and do the linear smoothening

Eskil, this doesn't seem to improve the situation any here.

Maybe you could look at this again?
