## n_alSndpSetPitch

Syntax

    #include <n_libaudio.h>
    void n_alSndpSetPitch(f32 pitch);

Arguments

- 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
This function is available in the n_audio library. It sets the pitch of the current target sound. If the pitch argument is a fraction less than one, the pitch goes down; if it is greater than one, the pitch goes up. If the sound is playing, the pitch is adjusted immediately. If the sound is not playing, this call changes the pitch of the sound when it is played.
To set the target sound, call n_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.
