/**
* Change the frequency ratio of an audio stream.
*
* The frequency ratio is used to adjust the rate at which input data is consumed.
* Changing this effectively modifies the speed and pitch of the audio.
* A value greater than 1.0 will play the audio faster, and at a higher pitch.
* A value less than 1.0 will play the audio slower, and at a lower pitch.
*
* This is applied during SDL_GetAudioStreamData, and can be continuously changed
* to create various effects.
