Public Slots
virtual void	receiveTick (const GapeFloat *values, int numValues)
	If a function unit recieves a NULL tick it will emit a mono tick with the next sample in their waveform, otherwise it will add the next sample (scaled by the current gain) to as many channels of as it receives.
Public Methods

virtual void	fillBuffer ()
	Pure virtual function which fills the FunctionUnit's internal buffer with data representing one period of a waveform. More...

Detailed Description

Used to play a sample from a file, and have control over frequency, etc.

Essentially fills our wavetable buffer from a file. The file specified must be smaller than GAPE_FILE_SAMPLE_UNIT_MAX_SIZE (in samples) which right now is about 4 secs at 44khz. If the file is multichannel, it gets mixed down to mono.

Parameters:

parent	the parent widget for our controller
filename	the name of our file, which can be no larger than GAPE_FILE_SAMPLE_UNIT_MAX_SIZE (in samples)

Member Function Documentation

void GapeFileSampleUnit::fillBuffer ( ) [protected, virtual]

Pure virtual function which fills the FunctionUnit's internal buffer with data representing one period of a waveform. You must allocate storage for this buffer (which is designated by the sampleData pointer) and also set the length of the data (in samples) in the variable dataLength. Deallocation of the data is taken care of by the destructor. Reimplemented from GapeFunctionUnit. Definition at line 271 of file gapefunctionunit.cpp.
