Detailed Description

An easy to use FFT scope, stereo version. You certainly want to reimplement scopeEvent()

Definition at line 208 of file plugin.h.


Member Function Documentation

virtual int StereoFFTScope::bands  )  const [virtual]
 

the "width" of each scopeEvent

Implements FFTScope.

void StereoFFTScope::scopeData std::vector< float > *&  left,
std::vector< float > *&  right
 

get the current data pass two vector<float>*, this will do the rest. do not allocate it beforehand. you must then delete the vectors

Returns:
the amount of elements for both left and right

virtual void StereoFFTScope::scopeEvent float *  left,
float *  right,
int  len
[inline, virtual]
 

called according to the timeout the two floats contain the data, with len items you override this yourself

Definition at line 219 of file plugin.h.

virtual void StereoFFTScope::setBands float  f  )  [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

Implements FFTScope.

virtual void StereoFFTScope::timeout  )  [virtual]
 

cause a rescoping to take effect immediately

Implements Visualization.
