SetSoundFrequency(#Sound, Frequency [, Channel])概要
Set the new frequency, in real-time, for the sound. The new frequency value is saved for the sound, so it's not needed to call it every time.
参数

It's the value returned by PlaySound() when using the #PB_Sound_MultiChannel flag. If #PB_All is specified, all the channels of the sound are affected.
