## Public Member Functions
unsigned int | channelsOut (void) const
| Return the number of audio channels in the data or stream.
const StkFrames & | lastFrame (void) const
| Return an StkFrames reference to the last computed sample frame.
virtual StkFloat | tick (unsigned int channel=0)=0
| Compute one sample frame and return the specified `channel` value.
virtual StkFrames & | tick (StkFrames &frames, unsigned int channel=0)=0
| Fill the StkFrames object with computed sample frames, starting at the specified channel and return the same reference.
Public Member Functions inherited from stk::Stk
void | ignoreSampleRateChange (bool ignore=true)

## Detailed Description

STK audio input abstract base class.

This class provides common functionality for a variety of audio data input subclasses.

## Member Function Documentation

## ◆ lastFrame()

const StkFrames & stk::WvIn::lastFrame | ( | void |  | ) | const
| inline

Return an StkFrames reference to the last computed sample frame.

If no file data is loaded, an empty container is returned.

29{ return lastFrame_; };
