SoundPitch sound_variable, hertz
Parameters:sound_variable = any valid sound variable previously created with the LoadSound command.
hertz = valid playback hertz speed (up to 44000 hertz).
Description:Alters the pitch of a sound previously loaded with the LoadSound command. By changing the pitch, you can often reuse sounds for different uses or to simulate a 'counting up/down' sound. To make the sound 'higher pitched', increase the hertz. Conversely, decreasing the hertz will 'lower' the pitch. Note: this is in relation to the original hertz frequency of the sound.
; Load the sound (11,000 hertz) snd1Up = LoadSound("audiooneup.wav") ; Play the sound normally PlaySound snd1Up ; Change the pitch UP and play it SoundPitch snd1Up, 11000*2 ;twice original frequency PlaySound snd1Up ; Change the pitch down and play it SoundPitch snd1Up, 11000/2 ;1/2 original frequency PlaySound snd1Up
up to 44000 hertz
I tried higher, and it worked.
If you want to change the pitch while the music/sound is playing, then use "ChannelPitch".
