Some user feedback I can point to is that pink and brown are too 
"similar". The Manual says that brown "has the most muffled, low 
pitched sound of the three types". I don't sense the muffled or 
"low pitched" very much compared to pink in the currently released
noise. Steve's previous brown noise samples were an improvement
IMO, but I have not tried his latest patch.  
  
Someone said "brown should be sensed as loud (bassy) enough
but still relaxing - it's the best noise for brainwave entrainment
(or should be). Think a loud waterfall."

Not seen any, though they may be implied by the comments 
about pink and brown being too similar. 

Other comments I've seen:

* Add Blue or Violet noise (4 votes)

* Make the peaks of brown and white what the user asked 
   for.  0.5 amplitude means that Amplify gives you + 6 dB
   and certainly the noise peaks should not get louder the 
   longer the noise (3 votes)
