Detailed Description

Upsamples input by integer factor using chosen interpolation. Frame size is also increased by the same factor.

Upsamples a signal by a factor n so that `out[t]=in[n*t]`. Also runs some kind of interpolation to find out the value for unknown samples (see description of the **mrs_string/mode** control).

Controls:

• mrs_natural/factor [w] : Adjust the upsampling factor.
• mrs_string/mode [w] : Change the interpolation mode
  • "none": unknown samples are unchanged.
  • "repeat": unknown sample [t] equals known sample [t+1]
• mrs_float/default [w] : Unchanged values are set to this value.

MarSystem * clone

(

)

const [virtual]

Implements MarSystem.

Definition at line 35 of file Upsample.cpp.

void myProcess	(	realvec &	in,
		realvec &	out
	)		[virtual]

Processes data.

Parameters:

in	Input data to read.
out	Output data to write.

Implement this method in subclass to define specific data processing.

Implements MarSystem.

Definition at line 62 of file Upsample.cpp.

void myUpdate

(

MarControlPtr

sender

)

[virtual]

Updates internal state due to a control change.

Parameters:

sender

The control that triggered the update; more precisely, any control passed to the update() method - could be an invalid one.

Implement this method in subclass to define specific response to control changes.

Reimplemented from MarSystem.
