Detailed Description

STK "singing" looped soundfile class.

This class loops a specified soundfile and modulates it both periodically and randomly to produce a pitched musical sound, like a simple voice or violin. In general, it is not be used alone because of "munchkinification" effects from pitch shifting. Within STK, it is used as an excitation source for other instruments.

Constructor & Destructor Documentation

stk::SingWave::SingWave ( std::string  fileName,
bool  raw = false 
)

Class constructor taking filename argument.

An StkError will be thrown if the file is not found, its format is unknown, or a read error occurs. If the soundfile has no header, the second argument should be true and the file data will be assumed to consist of 16-bit signed integers in big-endian byte order at a sample rate of 22050 Hz.


Member Function Documentation

StkFrames & stk::SingWave::tick ( StkFrames frames,
unsigned int  channel = 0 
) [inline, virtual]

Fill a channel of the StkFrames object with computed outputs.

The channel argument must be less than the number of channels in the StkFrames argument (the first channel is specified by 0). However, range checking is only performed if _STK_DEBUG_ is defined during compilation, in which case an out-of-range value will trigger an StkError exception.

Implements stk::Generator.
