Feedback from Philip in http://lists.w3.org/Archives/Public/public-audio/2012AprJun/0433.html

«This is certainly an improvement! More feedback:

The sampling of k-rate parameters is not defined, the sensible options  
would seem to be either the average value over one working buffer (128  
samples) or picking the first, middle or last sample for that work buffer.  
In other words, if a signal oscillating between 0 and 1 at 20 KHz  
oscillator is used to control delayTime, will it be effectively a constant  
0.5 second delay or a "random" delay for each work buffer depending on the  
phase of the signal?

Editorial issues:

"Please note that the <code>frequency</code>, <code>Q</code>, and  
<code>gain</code> parameters are <em>k-rate</em>" can be replaced with  
"All parameters are <em>k-rate</em>".

Lowercase and uppercase MUSTs are now both used, presumably not  

Typo: coursely -> coarsely
