Function Documentation

generateSinWave()

void generateSinWave	(	short *	buffer,
		double	frequency,
		double	volume,
		int	sampleRate,
		int	numSamples )

Generate a sinusoidal wave with a specified frequency and duration.

This function generates a sinusoidal wave with the given frequency and duration. The waveform is stored in the provided buffer.

Parameters

buffer	Pointer to the buffer where the waveform will be stored.
frequency	The frequency of the sinusoidal wave in Hz.
volume	The volume of the waveform (scaled between 0 and 1).
sampleRate	The sample rate of the waveform (e.g., 44100 for CD quality).
numSamples	The number of samples in the waveform (likely, the length of buffer).

getFrequencyRelativeToFrequency()

double getFrequencyRelativeToFrequency	(	double	frequency,
		int	semitoneDistance )
