Sets the pitch of the specified voice
#include <libaudio.h> /* libaudio.h */ void alSynSetPitch(ALSynth *drvr, ALVoice *voice, float pitch);#include <n_libaudio.h> /* n_libaudio.h */ void n_alSynSetPitch( N_ALVoice *voice, f32 pitch);
alSynSetPitch sets the rate that indicates how the synthesizer will play sound of a wavetable. The pitch can range from between 0 and 2.0 (but not 0). If the sample rate of the wavetable is the same as the output rate set by osAiSetFrequency, then: A value of 1.0 will play the sound with no pitch change. A value of 0.5 will play the sound pitch shifted down an octave. A value of 2.0 will play the pitch shifted up one octave. Negative pitch values are not supported (undefined). 0 for pitch value cannot be specified as division by 0 cannot be operated. Values greater than 2.0 will be automatically adjusted to 2.0.
