alSndpSetPitch
Syntax#include <libaudio.h> void alSndpSetPitch(ALSndPlayer *sndp, f32 pitch);
Arguments
- sndp is the pointer to a sound player
- pitch is the pitch value (1 for the original pitch, fractional values for lower pitches (for example, use .5 for an octave lower than the original pitch), 2 for the maximum (an octave higher))
Explanation
It sets the pitch of the current target sound. If the sound is playing, the pitch will be adjusted. If the sound is not playing, this call will effect the pitch of the sound when it is played.
To set the target sound, call alSndpSetSound.
The maximum allowable pitch is 2.0. Values greater than 2.0 are clipped to 2.0 when the sound is played. The minimum allowable pitch is 0.0001. Values less than 0.0001 are clipped to 0.0001 when
the sound is played. Note that this value represents the
practical limit for pitch shifting because it causes a 20 kHz
sound to be played at 20 Hz.
