Member Function Documentation

virtual int FFTScope::bands  )  const [pure virtual]
 

the "width" of each scopeEvent

Implemented in StereoFFTScope, and MonoFFTScope.

float FFTScope::magic int  bands  )  [static]
 

returns the magic number that you can give to "setBands". For example:

 setBands(magic(50));
 bands()==50
 

virtual void FFTScope::setBands float  n  )  [pure virtual]
 

set the width combiner value. in theory, a value of 1.0 should give you exactly 1024 samples, greater values will decrease the amount quite rapidly. by default, 1.1 is used, which gives 50. You'll have to tweak this manually.

This will only return valid responses for values between 10 and 1024

This function is a terrible hack, and we apologize for it. The values of these magic numbers do occasionally change, so you must use magic

Implemented in StereoFFTScope, and MonoFFTScope.
